according to an Iron Horse news from back in the day, the 3 way stub is supposedly from the west side of Alpine Tunnel. Bob & Co. went up in the 50's and dragged it out. Back then there was still a lot of track in place still up there. Now how much of the rail in Golden is actually from Alpine is a question that I'm not sure anybody can answer but that's the story

Tram driver here. We use exclusively flop switches (by your terminology) for points, for diverging and converging routes. The idea is if we ever have to run reverse, we don't need to pre-set the points - we're in mixed traffic with cars - and we can just drive the tram. Our flop switches are designed that they can have the returning spring biased, to make them a set of spring points. It's the same mechanism, just the bias in the spring is adjusted. We use them for terminii, so that trams always leave on the correct track. Diverging points often, but not always, have a hydraulic motor attached for automatic operation; all points have a manual throw, operated by a big metal bar operated by the driver. Pushing against the hydraulic motor is... work, but completely managable. Trying to manually throw a spring-loaded set of points is a great way to have 'a bad day at the office'. Frogs are all of the flange supporting variety, but our heaviest vehicles have around 7.5 ton axle loading. They still wear out over time.

Also, an awful lot of traditional tram switches have just a single point (plenty of examples here on the MBTA = Boston area Green Line). I have heard that a lot of modern off-the-shelf trams don't play well with these. (Then again, MBTA Type 8 trams don't play well with anything, including straight track, unless you grind the wheel profile to be really nonstandard, and even then it's a bit iffy.)

I don't know this for sure, but I think perhaps the frog in the railroad switch is named after the frog in a horse hoof, not after the amphibian. The frog is a bit of soft tissue that is up inside the hoof, it makes contact with the ground when the ground is soft and is basically like the single fingertip of the single digit of a horse's foot, whereas the hard part of the hoof is the fingernail that wraps around it. The shape of the piece is pretty evocative and I think that the smiths that were hand making the rail hardware in the early days would have a lot of familiarity with horse hooves.

It may even come from the clothing fastening called a frog. Each side of the gap to be fastened has a cord often shaped like a "Y" with the points at the gap to be closed. One point has a loop and the other has a knot like a ball that goes into the loop like a button to fasten. When it's fastened, it's shaped a lot like the railroad switch "frog". But again like "For a Minute" says, that name might come from its resemblance to the eponymous critter.

It's so interesting to me to see the differences in standards and terminology. I'm currently training to be a train driver (dont know the peoper term sorry) in Austria, and there isn't a single term that translates directly. What you call the guard rail we call Wheel Steerer (Radlenker) if translated directly. The frog, which you said is sort of the heart of the switch, we call switch heart (Weichenherz), and the points, the moving bits, we call switch tongue (Weichenzunge). Incredible is also your systom of switch signalling. We just have arrows that point in the direction the switch is set to take the train.
@thesteelrodent17963 ай бұрын
It's the same in Danish. The guard rail is "force rail" in Danish, but the rest is basically the same as German - tongues and heart piece, while the rails are outer or middle-rail. We use slanted lines instead of arrows to indicate the direction of the switch, but our track is normally made so the indicators work the same way as the American, so | means you're going down the line, and / means you're going off the line. The confusing part is that these flags were also used on double slip switches, so if the flag says |, then the switch is set to X, but if the flag is / (or \) then the switch is set to )(. Of course on automated switches there are no flags at all, so you just gotta hope it's set right. We only still have flags on switches that allow or require someone manually flipping it

One thing you didn’t get to cover since you talked mainly about historic switches but modern switches can get quite large to allow higher speeds through the diverging leg. For example there exists 2 switches in the US rated for 125mph on the diverging leg, one on the Northwest Corridor and one of the Orlando extension of Brightline in Florida. These 125mph switches are so large that they need 5 switch motors to throw the switch, 3 for the points and 2 for the Frog.

Any law in the world makes the vehicle that crosses any rails be liable to damages. The train or rail vehicle gets priority every time. The US seems to hate rail vehicles to the point of blaming them for the accident. Even common sense is hard for them. Famous trams in Europe gets the usual dose of vehicles trying to fight a tram on the road. The tram wins every time and the driver at fault also gets the intense stare from the passengers of the tram for making them late.

@@kimpatz2189 Not true at all. Sorry but that's completely idiotic to say that. If its a level crossing for example, where the lights, and or gates fail to operate, or if the driver of the train passes a red, then its no fault of the road user. Not every collision with a rail and road vehicle is the road users fault. In fact just up the road from me, (Kent) the train crew are responsible for operating the level crossing gates, so they are responsible for stopping to make sure the line is clear, before proceeding across the road. Not everything is black a white bud.

So the frog number is the arccotangent of the acute angle between the tracks. Cool to see some of these "weird" trig functions in practical use! It sounds complex, but it makes it *really* easy to lay down where the rails need to go when your most reliable tools are measuring tape and a square angle. #10 is 5.71° and #8 is 7.12°, and establishing a 2° difference with just a protractor would be a nightmare to do in steel.

It’s easier to think of the switch no. as run over off-set. The ‘measuring unit’ is not important. Just that the the same units are used. Grab a stick (or use your shoes), measure out from frog point as many sticks (shoes heal to toe) as required until the rails are one stick (shoe) apart. Instant switch number. 👍

There are two kinds of "harp" switch stands, depending on the positions of the pivot and the link to the rails. If the pivot is below the link, the indicator arm & flag indicate the thrown route as expected. If the pivot is above the link, then it's opposite: the flag is to the left if the throw is to the right. A flag straight up&down is for the straight route, for either kind.

@@reverse_engineered If the flag is straight (up), then the switch is lined for the straight branch. If it's to the side, (either side), then it's for the diverging route.

You would be able to see how it's lined, if you were unfamiliar with this switch or what that railroad's normal practice is.

Something common on the rail lines in my area are spring frogs. The frog has a movable point that makes the through route a solid rail, and the only gap is for the diverging route that the flange shoves open. These frogs don’t allow light speeders track equipment and hyrails to pass through the diverging route so crews have to drive a spike in to temporarily open the frog. A different line in my area has 70 lb switches with NO heal blocks. They worked fine in the 1910’s when the RR was built. These days with heaver equipment…. Not so much.

6:00 I had heard a long time ago that the FROG was an acronym for Flange Roll Over Guide/Groove. Some engineer (the construction kind, not the train kind) came up with this thing and likely named it for it's function as engineers often times do, to allow the flange to roll over where the rail would be if groove or guide wasn't there as cleanly and controlled as possible, which to me anyway, makes a lot more sense than trying to pull an abstract visual of a smashed amphibian or some other animal part as a reason why it is called that. Now it really could be because it didn't actually have a name and someone thought it looked like a smashed frog or something else and everyone ran with it, but that story just seems like something that MOW crews would always tell the new guy to get a cheap laugh when they heard him tell the next new guy some time later and now it's less a running gag and more of a legend. We do things like that for the laughs in the industry I work in all of the time too.

TM 2.1.3 from CAHSR goes over a bunch of the physics behind making switches comfortable to traverse at high speeds. 110 or 150mph diverging is not common here. RR06-10 from the FRA goes over some interesting changes that could be made without changing stuff like frog profile to increase the diverging speed.

There was one time on a shortline I threw one of those more "ergonomic" switches in a BNSF yard for interchange. It must have been out of adjustment, because even with my full weight on it (admittedly not much at the time) I couldn't make it close, and my engineer had to come help me. Regarding the future diamond...if I'm seeing that right, you're going to have a bunch of curved frogs in there (that is, one or both rails is curved within the frog and past it). Sounds like a pain. Then again, streetcars and light rail often have to deal with curved frogs too. One more note: There was apparently a type of switch stand out there known as an "E-Z Throw" switch. Don't know how the linkage works exactly, but you spun a larger wheel in order to throw the switch. For some reason, one of those was installed at McEwen a couple years ago, so you'll have to come to the SVRy to check it out. I guess that would make it a "steering wheel" of sorts?

Using "green = main, red = secondary" on switch targets is such a terrible idea. That way, every crew has to remember whether the main route is the straight or diverging track for every single switch on the railroad. That gives so much opportunity for mistakes. Imagine what a mess the roads would be if traffic lights used "green = main route goes, red = side route goes" instead of "green = go, red = stop". Switch targets are a safety system, and consistency is so important in safety systems.

Interesting to see these manual switches being secured by a simple padlock. I've been a switchman for two years, working at a coach yard (or more precisely EMU depot) in Warsaw and most of the switches aren't secured at all, aside from one that's linked to a derailer via a set of dedicated keys. There's a special lock that keeps the point aligned to the stock rail, making it physically impossible to throw the switch unless you opened it with a key sitting in the derailer's lock, which in turn has to be opened with a key that's located in the switchman's post. This dependency is a simple yet effective safety measure preventing from operating these devices separately. Also what's interesting about these US manual switches is that the connecting rod itself lacks some kind of locking mechanism that secures position of the switch, like on most European railroads where it's either a rotating hook or a set of sliders that lock between each other when the switch is thrown to either side. And the switch stands themselves feature a large circular counterweight on the lever which makes operating a switch safe and easy.

Another thing to touch on is modern switches, electric and hand throw, have a connecting rod that locks them in position. That "lock rod" has a bend in it so if the switch is run, the energy isn't pushed into the switch itself, but just bends the lock rod more. It almost looks like an offset bend in electrical conduit. I work on Alstom model 5 and model 6 switches and they all have these offset lock rods installed.

about running the switch wrong: it's a common thing to have spring loaded switches in trams for that very reason. Trams are lightweight and take switches at rather slow speeds, so its feasible to have their switches spring-loaded. Also in denser tram systems (like in my hometown of Heidelberg, Germany) you just have so many switches that it'd take ages if they all had to be explicitly set every time a tram runs them the wrong way, so it's more convenient to have them spring loaded

I watched a car pick a switch as I was standing by the lead verifying the manifest. The car actually picked the points, and before I turned to walk quickly away I saw the points lift up under the car. Run-through switches were not uncommon when I worked for the RR. The part that broke was called the hub, and was designed to be the part that would fail during a run-through. Replacement took a few minutes, and it was a simple procedure. When I was 15 I rode with my dad as he ran an E8 with about 9 cars into Washington. The train was wye'd and backed into the terminal. After the locomotives were uncoupled I sat in the engineers seat, and when the signal at the end of the platform track turned yellow he instructed me how to release the engine brake and open the throttle a notch at a time until we started to move. A number of RRs shared DC Union Station, the B&O, PRR, SOU. With 24 tracks converging then diverging the interlocking was, and still is complex.

At the Museum I volunteer at we have a interesting ground throw switch. The lever is set in side between the points. This is only because of the location. road is on one side and the rest of the yard tracks are to the other. there is no safe place besides the center to place a stand or normal ground throw.

in Germany we have totally different names for the switch: Switch: Weiche (Switch) stock rail: Backenschiene (cheek rail) points: anliegende/abliegende Zunge (adjacent / distant tounge) heel block: zungenende (tounge end) connecting rods: Weichenstellvorrichtung (Switch setting device) switch stand: Weichenantrieb (Switch drive), Rotary switch stand: Handweiche (Hand switch) the frog: Herzstück (Centerpiece/ Heartpiece) Guardrail: Radlenker (Wheel handlebars) We also differentiate between the direction the train is going onto the switch: Guardrail side: Stumpfe seite (Blunt side) point side: Spitze seite (pointed side) This is mainly for safety reasons as you know that you can you can drive up a switch from the blunt side which can damage the switch, and if you drive onto the switch from the pointed side and the switch isn't set correctly... well you can derail.

Good job there Mark! Another interesting bit of basket weaving in iron is the frogs in that 3 way. The first frog is longer than the next two which are usually side by side - 3 frogs in all. About the only effective switch stand for a 3 way is a harp switch stand. Also, the short silver spring switch at the end you said was weird - we used those type at Lakeside. They are good for mining and trams. Easy to throw and you can run through them through the trailing point side and they spring over. Did it several times with the diesel on the way to fires when the steam train was running.

I hadn't heard about those switch numbers before. The (European) model railroad brands I know only mention the angle of the switch and the length of the straight track. Roco (H0 scale) for example has 15° (length: 230 mm) and 10° (length: 345 mm) switches in their program.

The last stub switch I knew connected to the US rail (Standard gauge) network was in Corydon IN, it was near the end of the line into the old shop they had. They were not allowed to run occupied passenger cars over it and it had a, well go as slow as possible restriction on it. It was a point of pride with the railroad and it got a modern frog on it.

Great video. Very interesting, too. I heard that modern day frogs have special steel alloys at the point of the frog. The alloy is there to reduce the breakdown of the frog where the wheels impact as they cross over.

An old railroad called the Raritan River Railroad ran behind a apple orchard across from where I grew up in New Jersey. I use to walk back to see the train and ended up getting to know the guys that ran it. They had several switches and when they had to get on a spur they would let me help move the switch. I was maybe 8 at the time and I thought this was great.

Nice and informative video. I've only seen the stub switch once before. Quite cool and interesting. There are two other types of frogs. There is the self-protecting frog, with no guard rails and the movable frog. You've seen self-protecting frog on many rail lines, with the 'guard' rails, which are built into and stick up on either side of the frog, for lack of a better term. The movable point frog is spring loaded and moves as the flange hits what is basically a lever to push the movable part over. This has no permanent, or defined flangeway for the industry lead, which is usually where these switches are found, although there are some found on hand-throw sidings and the like. When lined for the main, there is no flangeway on the diverging route for the wheels to run over, making a very smooth and quiet switch to traverse. I wish that I could explain these things a bit better. Great video.

I got a lot out of this video and it showed some great scenes of well care for railway and its grounds! The 3-way stub switch I thought was interesting because it allows a true 3-way route selection. That would be about the only reason a stub switch would be used today and only for long term storage track use with almost no traffic. I think railroad museum should display track geometry's of various forms though history and in current use in interesting ways. The thinking behind them is educational for abstract mechanisms. Running on rail wheel flange circumference as normal practice is a little unclear if it is really intended. It allows track work to lift the rail wheel up and support it continuously when the rail head has gaps in it.

One reason railroads are less dependent on lamps backing up signs is the advent of retroreflective materials. The sign can return the headlight beam to the locomotive. I bet you can find the interim technology around the museum: glass "cat eye" dot reflectors. The 3M material actually has the same optical behavior on a microscopic scale. If you want to see if material is retroreflective, take a camera phone picture with the flash on. 4:09

Depends on the switch. A stub switch, no. You'll absolutely derail. A "split" switch with sprung points, yes. If those points aren't sprung, you may derail, booger up the switch, or both. A "tongue" switch, as often used for streetcar lines, probably not... but I wouldn't.

I actually didn't know a little bit of the information you provided. Excellent work. I have to say, though I have seen a few switches that you didn't include because of how rare they are. The single point switch, I thought you'd put in from when you go from 4-track to 3-track dual-gauge. The other one I remember is from a magazine on railroad models from the 70s that has a point against the main stock rail, a sliding rail for the diverging stock rail, and a turntable for the frog, as the diverging side was a dual-flanged wheel (a flange on each side of the tread. Used for a rail crane at an industry/port. If I find it, I can send you an image). Keep up the good work...and wish me luck: I'm going to apply for csx as a conductor and see how that goes.

It's amazing seeing the differences in rail and switches over time. It's especially funny to me because a lot of what you said isn't used much anymore seems to be quite common where I live! I'm in Saskatchewan, Canada, and there are trains everywhere carrying grains and oil across the country. Every little town and city is build around a railroad. This area was originally settled to make it cheaper to build the rail between the East and West coasts! I used to live by a grain elevator in a small town and now I live near a switching station in the middle of a busy city. In both cases, I still see those vertical rotary stands used everywhere. Some parts of the system are operated remotely now, but a lot of it is still using these old hand-cracked switches. If it ain't broke, right? :)

as far as I know, the reason switch frogs are called that is due to the similar structure of the same name on the bottom of a horses hoof, best understanding I have for that is because the structure looks kinda like a frog's pelvis, but the frog of a horses hoof is a V shaped structure that looks quite similar to a switch frog, and from what I understand it's from there that early train crews saw the resemblance between a switch frog and the frog of a hoof, and the name just never changed because railroads

the most common location where Wheelsets will derail at Switches is at the points on a switch that is out of adjustment or excessively loose allowing a worn Flange to pry itself between the point and Stock Rail "Picking" the switch. most switch stands have a connecting bar made of soft iron designed to sheer off if the points are forced over by an incorrect movement of traffic. this spares damage to the stand proper by breaking at an easily accessible location with a piece intended to break and easy to replace. often designed as a double ended item with a Center pin attached to the stand proper and a socket on either end attached to the connecting Rod.

Did you get to walk down through the yard while you were at the East Broad Top? There's a 3-way stub switch near the south end of the shops. It and the one you guys have at the Colorado Railroad Museum are the only surviving 3' gauge 3-way stubs in the US (and the EBT's is the only one in its originally installed location). There's also a pair of standard gauge 3-way stub switches in the EBT Mount Union yard (which not Foundation property, sadly) on either side of the standard gauge scale. Loaded hoppers were gravity switched from the North Standard Gauge Yard, which converged on one 3-way stub at the north end of the scale, weighed, and sorted into the South Standard Gauge Yard by the other 3-way stub switch immediately opposite the scale (come to think of it, that'd make a neat model).
