T1 Video Memories of Pennsy Steam

Brought to you by The T1 Trust a Non-Profit Organization formed with the express purpose of constructing T1 5550, one of the first main-line steam locomotives constructed in over 50 years. Here is a fantastic video of T1 action from Mark I Video Productions one of our gracious sponsors.

[@gtrfraner]

3:58 well i've never seen a T1 go that fast.

[@gundamwarrior]

Yep, its easily pushing 110+ mph there. It takes just 3 seconds to pass 4 poles which have by my best guess at least 120+ feet distance between each pole given how it looks like each one is around the length of the locomotive itself? So doing some math it passes by all 4 within the course of 3 seconds. Thats pushing 110 miles an hour at the minimal. Depends how far the distance between each pole is. They do say the T1 is capable of pushing into the 140 range given the right conditions and some unverified runs back in the day claiming to having done so. But thats what the recommissioning of the T1 trusts T1 is all about, breaking that record.

[@mcfc_lads1894]

Nothing compared to the s1. it was rumored that one had reached 156 mphs. dwarfing this and basically t-bagging on mallards speed record of ‘125 mphs’. Personally, I believe this theory because they were honestly pretty fast steam engines. And their streamlining probably gave them better aerodynamics and and more speed.

[@rayhankazianga6817]

@@mcfc_lads1894 How in the heck would a locomotive so long that it could only be used on one route and had catastrophic wheelslip issues, along with a complete inability to tilt reach 156 MPH?

[@tomstradetable6940]

There is a new one in the works

[@PrekiFromPoland]

I don't find that hard to believe though. Maintenance of this behemoth costed a lot both in funds and manpower and their design couldn't be improved any further. More power meant higher axle loads, bigger boilers (and thus reduced visibility) and in the end, operational complexity that was overly expensive when compared to diesels. It would be nice to see one T1 preserved, but the post-steam era in the US was a time when lots of unique locomotives were scrapped without second thought. These steam locomotives make their European counterparts look like toys.

[@tomstradetable6940]

Yeah, the main problem is the stupid 4-4-4-4 wheel set on a fused axle....just removed any value of using sets of 4, causing low traction and bad turn radius. The other problem is the drain of pressure those two sets of pistons had, leading to fast speeds, then slow low pressured running with wheel slip and grinding.

[@AndrewHager02]

TomsTradeTable And the fact that the people behind this project think they can beat LNER A4 Mallard’s speed record with such a locomotive as this is embarrassing. A locomotive for heavy passenger and freight trains, sure, but to break the top speed record? No. Just no.

[@TheMasterClue]

a vast majority of the T1's issues were do to abuse from engineers who were used to running underpowered K class locomotives. The Norfolk and Western tested T1 5511, and noted that it did have a higher fuel and water consumption per horsepower than an N&W J, and it required more maintenance than they thought a modern steamer should require. They even made the suggestion to the PRR to change the valve gear over to Baker valve gear like they used on the J to lower maintenance cost. T1 5511 did have trouble starting a train on a grade the J class had no issues with, but that was due to its tall drivers (80" vs. 70" on the J class). In the end, PRR's pride and ignorance killed the T1, and led to its short career.

[@TheT1Trust]

The T1 was designed to operate anywhere on the PRR mainline circa 1942. With the original lateral motion configuration, the T1 could negotiate 16 degree curves, and according to the timetable, could operate in areas where even the M1 was restricted. Based on the lateral motion increases of 1946 and the overall dimensions, we're confident that the T1 can operate anywhere on the current mainline network that the N&W J class can. For more information: prrt1steamlocomotivetrust.org/faq.php

[@hiawathabeast]

Dan Fitzgerald ok, that's just hogwash. this engine is NOT a poor choice to build from scratch, with all the myths surrounding this class finally being debunked, 5550 would, if built, finally address them all. as for a poor choice, HA, choosing to recreate Illinois central no.1 is a poor choice. at least the T1 had SOME success, IC no.1 was a terrible choice for freight. also, saw your comment about how this loco couldn't be driven anywhere unless articulated, I already said on here T1 5511 was tested on the Norfolk and Western, if a T1 can go on the same tracks as N&W 611, it doesn't need articulating.

[@Thunderbolt_1000_Siren]

Dan Fitzgerald funny enough they are actually beginning to build her

[@daylightbigboy]

+hiawathabeast You said it! I found that the wheel slippage was caused by spring equilization. The bogie trucks held the same weight as the engine trucks which means that the adhesion was terrible. The 6900 horsepower in a loco the size of a northern didn't help either. The excessive wheel slip wore the poppets much quicker than they should have. Basically, fix the adhesion and all the other problems will be fine.

[@russellgxy2905]

This is why I don't get why people are so upset about you guys building a T1 instead of a Q2. The Q2s might've had the highest recorder horsepower for a rigid steamer, but they were extremely heavy (less route availability than a J1) and had standard Baker valve gear; must've cause a ton of hammer blow. Sure the T1s cost a lot of time to maintain, but they were the ultimate passenger engines. Two sets of drivers and they didn't need to go through the complexity of being articulated. Besides, with a T1, there's a guarantee that you can actually run it somewhere. Where would you run a Q2 exactly? Maybe out west, but most of the Western steamers are oil burners.

[@frederickmiles327]

Some say they are the fastest steam engines that ever ran an up to 125mph might actually have been achieved in their 4/5 years of actual service. Most would go for a Chapeleon Pacific or the NW J which was designed to be stable at 145mph on the Pennsylvania main line and was probably a more realistic idea for the last steam but the NW line at the time was steep and ran through nowhere the deepest Apalachia, so only the first 100 miles out of Norfolk Virginia the great US Navy port would see them fly. Thats what I se those NW express engines as the transport to the US Navy at Norfolk, connecting with the Penn at Cincinati. That Navy passenger traffic is what probably made the NW passenger service plus the US Mail until 1970 and the Amtrak takeover.

If I'm gonna be honest, I can totally see the looming oil crisis causing us to end up returning to using something along the lines of a T1 for getting around long distances. Though probably it'd be best to follow modern steam practices (GPCS, water treatment, Lempor, internal streamlining). Also these things look dieselpunk as hell. I really like the duplex wheel configuration, I'm glad to see it getting a comeback at a very crucial time.

[@stlrfn3190]

Steam locomotives would never pass the noise and pollution levels in effect today. It would require major changes in technology.

[@lepidotos]

@@stlrfn3190 Kinda. Like GPCS, Lempor (both of which we've had since the '70s), and just not running it like a tourist operation that cares about photo shoots. Research done in the 90s suggests between comparable diesel and steam locomotives built in 1992, the released carbon monoxide is half the amount per kilowatt-hour of steam, the NOx is like 5% of diesel's, and the sulphur dioxide is maybe 3x diesel's, 2 g/kWh (on par with NOx). The only GHG steam produces a significant amount more of is, well, steam, but that's not really a big deal since it doesn't last long and isn't that potent compared to the other three. A lot of the image of steam having thick exhaust is it being run wastefully for photo ops, clean stacks were definitely what the railways wanted in the first steam era and you could get officially punished for intentionally being wasteful of company fuel. Training firemen to be efficiency-first and just ignoring the people complaining about not getting their black plumes to get off to is probably 75% of the solution on its own. There's also stuff like biofuels that should make things carbon-neutral, which doesn't help as much for the othet GHGs but it's better than present so it's a win. Plus, that would eat into kudzu and water hyacinth and tumbleweed growth. I couldn't tell you about noise, but it doesn't seem noise is being clamped down on too hard since I live right next to BNSF trackage and can hear horns going well past midnight. KZbin doesn't like links so I'll just tell you to look up the Advanced Steam Traction's website and read through it. Present steam designs get at best around 8% thermal efficiency but right now no research required you could get up to about 14% or 15%, and with a bit more looking into you could probably break the 20% barrier to be competitive with diesel on that front. There's also that you only need one steam locomotive for the work of four or five diesels, meaning that effectively those numbers from the first paragraph are quad or quintupled.

It passes by 120+ feet of distance between each pole, passing by 4 poles in only 3 some seconds. Giving you a min potential 110 mph.

By far my favorite locomotive! And, I'm happy people in this comment section will get my username!

Yeah! Broadway Limited over 20th Century any day! High Five!

[@ddkoda]

March of the articulateds. Good sound on the exhaust notes. Sadly with all their strength unable to escape the cutter's torch.

In these times, many railroads tried coming up with a rival for the Union Pacific Big Boy and Challenger

Would love to know the year these photo's were shot in St. Louis.

is everyone excited to se T1 5550.

I would’ve loved to seen a pair of those double headed!

The Municipal Bridge is called the MacArthur Bridge.

[@CarmenFiala]

3:58 that thing is HAULING. anyone know how fast that might've been going?

[@gundamwarrior]

If I had to guess, over 110 MPH. It passes by 4 poles in the matter of 3 some odd seconds watching the video and the timer. The distance between each pole is around the length of the engine itself, so you can easily rough estimate the speed it was traveling at. The T1 engine is 122 feet long not including the tender. So 122 x 4 / 3 = 162.6 feet per second. A mile is 5280 feet meaning 5280 / 162.6 = 32.4+ seconds to travel an entire mile at that speed. An hour is made up of 3600 seconds, 3600 / 32.4 = 111.1 mph.

​@@gundamwarriorI may be wrong but that's some SERIOUS dedication. You ain't a nerd, you're smart and I respect you for that.

[@kylestrasbourg4885]

8 years and the 5550 is completed.

[@crystalrock18]

It’s really to see video of what Saint Louis looked like before union station got turned into a giant parking lot. If time travel were possible I would to see that station back in 1945.

[@motormouth2472]

3:00 that must be what a T-1 whistle sounds like

[@iron1349]

What are you going to do with 5550 when it's done? Steam-hauled excursions are quite hard to pull off nowadays. Maybe 5550 will have less restrictions since it's a new build, or the Strasburg railroad could provide it a permanent home. But it will be great to see a new steamer in the States either way.

[@mychemicalbromance97]

iron 13 the hard part is insurance. Until recently, they could get insurance with Amtrak etc which is how 4449 and others were able to operate by meeting Amtrak standards. UP can ignore all of it since they own and insure all of their own equipment and track. And of course, running at high speeds is even harder since most tracks are rated for 60mph hour or less unless they are used by passenger trains and even then most don't operate above 60. Hopefully building with these goals in mind from the ground up means they'll be able to make it more insurable than a historic engine

[@whiteknightcat]

Amazing footage. I never even knew the T1's were operated all the way down to St. Louis, or was this a special occasion?

[@stlrfn3190]

Both the Pennsylvania and New York Central terminated in St. Louis. Pennsylvania had at least 4 crack passenger trains daily between New York City and StL.

[@zuiderzee9141]

One would imagine that training a crew (even one comprised of guys who are familiar with steam) to run this new T1 is going to be a bit tricky. From what I've read about them, wheelslip (and associated hammerblow) was a pretty big issue due to some crew's inexperience with the duplex-drive system.

[@hiawathabeast]

I've read about that too, however, you need experience with either a slippery engine (say an atlantic) or an articulated engine to drive a T1. sadly, PRR hated articulateds more than the duplexes (minus the Q2) and the crews that can drive them properly had cut their teeth on the atlantics, especially the E6. under a more modern RR's care, say the Norfolk & Western, but still working the Fort Wayne Division, the T1 would've been at their best. from what I've read the duplex behaved similarly to articulateds and trying to just yank on the throttle is asking for trouble, which is what many idiots on the pennsy kept doing because PRR didn't give them proper training.

[@absolutelyrandomful]

hiawathabeast While it's true that Pennsy didn't give them the right training, what kind of training can we give crews now in 2015? I honestly don't think if you run an Atlantic you're ready to run a duplex. An articulated, maybe, but's that's another problem. The only people who were trained directly by the guys from the 40s and 50s who are still alive with experience on articulateds on the mainlines, either the 3985 or the 1218, who could handle a duplex will probably be tied up with the Big Boy and the J coming back. A few years ago when things were quiet MAYBE you could pull them away but the UP and NS steam programs probably don't want those extra guys leaving now. While I believe NS will probably let them run a duplex if they had one, and while I believe with computers and models we MIGHT be able to fix all of their problems. who knows how to even run it? Also you gotta find a guy to fire, which I think you guys are overlooking. Even if an engine has a stoker, even an engine that runs on oil, there's a special way of doing that, too. And I can only imagine the firing needs of a duplex are vastly different than pretty much anything else out there.

[@hiawathabeast]

Random etc the atlantic comment came from finding out that some of the crews that tamed the T1 used to drive the E6, another slippery loco. the T1 isn't that hard to control, you just need a light hand on the throttle. one thing I found out from reading T1 researcher Dave Stephenson's posts, these locos respond instantly thanks to their front end throttles, give a light pull on the throttle and ease her up, no trouble. if you just yank on it like a monkey, it's gonna slip. concerning any firing needs, they're actually very easy to fire, and I think they do have a stoker, basically many coal-fired super power locos are equipped with them. I don't believe firing a duplex is vastly different to other locos. as far as who could drive them these days, well, I'm sure the trust will teach anyone who's willing to learn how to drive a T1 properly. I can't remember who said it, either Mr.Stephenson or a PRR fan, but, according to either one, articulateds and duplexes exhibit similar behavior. if that really is the case, then there's nothing to be worried about

[@manga12]

Random etc for one at the npk 765 open house one of the enginers for her is the technical adviser to the T-1 project so they are not as tied up as you think buissy yes but dont worry there are still folks that know the craft and how the steamers work, just not masses of them like used to be when they were the main pullers. the t1 was and certainly will be a power house when it gets finished, even if slow and steady wins the race, I will support her some how even if not right now.

[@manga12]

the poppets are a more effecient delivery design though, and they will likely only take it up that high just the one time to try for the record, the q2 is neat but its not a symetrical configuration 4-4-6-4 its an odd configuration.

[@quinnmattern2665]

Bet that will be running before 1361😉

[@thomastsangthomas1616]

These mighty T1 iron workhorses can actually hit a tremendous speed of 140 mph(224 km/h) and haul heavy passenger trains!😃 Capable to beaten some diesel locos at physical strength💪🏼and speed!🏃🏼‍♂️🏎️
