Blink and you'll miss it! Previously I had tried to calculate the speed of this monster, but my methodology was dubious at best, and led to the (incorrect) assertion that this train was moving over 67 mph. Although this train isn't nearly pushing seventy, it's still moving at a very good clip. I would still assert that it was cheating the 60 mph track speed just a little.

It never ceases to amaze me how deceptively fast a train seems to be going looking at it either head on or as it's going away. I guess that's why so many people think they can beat a train at a crossing. They just can't get it through their heads that the train wins every single time, with possibly passengers paying the price for the stupidity of the driver.

A stretch on NS through Camden Ohio is about a 6 or 7 miles long downhill grade of maybe 1%. not steep but no uphills and I've witnessed many crews getting back on schedule cause there's no way 60mph was the limit back in the day. Counted 93 cars galloping by in a minute and 19 seconds once 💨

How do you calculate the speed by counting frames?
@NickyDsTrains
@NickyDsTrains 5 жыл бұрын
It's all to do with the length of whatever passes through the frame. I tend to use locomotives -- anyway, the way to do this is by seeing how many frames a certain object takes to pass. Once you're done counting, divide the amount of frames the passing object took to pass into your total frames per second (for example, if something takes 45 frames to pass and you're recording at 60 frames per second, you would divide 45 by 60). The decimal you get here is the total amount of time the object took to pass. Copy this number to your clipboard (or something). It is vital that you know the length of the passing object, as it is used in the next step. Now, take the length of the object, in feet (remember, 3 inches is 0.25 of a foot, etc.), hit the divide button and paste the time decimal you got earlier. The number you're getting now is the object's speed in feet/second. Once you have this number, simply convert it to mph by multiplying by 0.682 to get your speed in miles per hour.

Three significant figures could be justified based on the use of the three-figure "conversion factor" mentioned in the reply to "TrainBrain107" below.

On the NS, it's 60MPH max for Intermodal. That's it, Never higher. The train in this video is going 62MPH at best accounting for speed adjustment. Counting frame rates is not an accurate enough way to calculate the speeds. A properly calculated professional radar or LIDAR gun is the only way to accurately tell these speeds without talking to the crew. Nobody has ever produced a video showing that.

@@northernpennrailproduction3373 not sure what your time frame is for “back in the day”. But it certainly wasn’t the last decade. The only place you would ever see an NS freight (or locomotive(s) running above 60 would be on another railroad. NS has a systemwide MAS for intermodal of 60MPH. They also have no trackage rated higher for freight. That’s why nobody has ever produced any proof of it. “Clocking” trains in videos is not accurate nor is pacing in vehicles on nearby roads. Had countless buffs insist they witnessed these occurrences with someone with a radar gun yet miraculously they all forgot the camera that day🤔 Still waiting for someone to produce a video with a radar speed showing one of these freights speeding. Quite a few buffs with radar guns AND cameras over on the NEC. But nobody seems to catch any of these freights.

Assuming that a line is Class 5 rated, it will allow a freight to travel at up to 80 mph. However, there are also factors to consider such as where a train is passing through, (is it through a town, street running like at La grange, Kentucky), how tight the curves are, the number of crossings it has to go over, weather conditions, etc. It seems to me, and this is strictly my opinion, the average speed of a freight train on any given day is between 30 to 40 mph.

Depends on the railroad and the division. The fastest freight speeds in the country are 70MPH for Intermodal trains. But the vast majority of that territory is the Midwest and points west of there. CSX has some 70MPH territory down south on the line to Fl. NS system wide has a max of 60MPH for Intermodal trains. CSX, BNSF and UP allow up to 70. Mixed freight on most railroads is 30-40. With 55MPH typically being the fastest. But all these maximum authorized speeds (MAS) are dependent on the division the train is on and the cars in the train. Their are a lot of types of cars and loads that require speed restrictions. So don't assume that if you are railfanning a division that (for example) has a 50MPH MAS for mixed freight that every mixed freight train you see is going 50MPH. Weather, track and signal work, traction, etc can all impact speeds.

Very very soon, we'll be seeing freight trains just like this one routinely cruising between 90-105 mph. The goal by 2025-2027 is to have developed the proper technology for locomotives of the SD70ACE T4 and the ET44AC T4 to have a top speed similar to the Siemens Charger, of nearly 120 mph. The current SD70ACE T3.5 and ES44AC are more than capable of 85-90 mph, but by law, they are only allowed to go up to 74.9, and 95% of the time, even intermodals go only up to 69.9 or 71 mph. In Europe, the DB electric freight trains can travel up to 95 mph. Our diesels have better motors than they do, but are geared towards torque rather than speed.

Not sure where you are getting your info from, but much of what you said is totally false. Their is absolutely no US goal of having freight travel 90-105 by 2025. In fact, some freight lines are dropping their speeds. Their is absolutely no goal to have freight locomotives reach a top speed of 120. They could attain that speed now with a simple motor change and software reprogramming. Their is absolutely no "law" that says freight locomotives can only go 74.9MPH🤣. Freight locomotive top speed is dictated by what the railroads want and the fastest speeds the tracks they run allow. Most freight cars have restrictions that wont allow speeds much higher than 75 anyhow. Any railroad could order an ET44 tomorrow with a 90MPH top speed, but why would they? Their is no freight equipment rated for it. And nothing that says Intermodals can only go "69.9 or 71 mph" by law. It's a choice by the railroads.

@@bossnaz7845 That actually has nothing to do with it. The overspeed governor doesn't limit the locomotives power output. It simply cuts the power off and applies the brakes to protect the traction motors and in turn, the MAS (Max Authorized Speed) on many Class 1's. The traction control system (AKA: Wheel Slip Control) on modern locomotives will limit power to each axle if it detects the wheels slipping, the same way ABS on a car limits braking when it detects slipping. Wheel slip is the single biggest limiting factor in the HP ratings on locomotives. Take as an example the GE EVO series. They have cranked out 4,400 out of a V12. They could easily get 5,000+ out of a V16. So why don't they? Because HP means nothing if you can't get that power to the rail. The technology does not exist at this time with the weight limits of locomotives to get the tractive and starting effort any higher than it is. It's like putting a 1,000 supercharged engine in a honda civic with stock tires. What good is 1,000 HP if when you can't get any traction and just spin the tires when you floor it? The MAS of a diesel locomotive is governed due to gear ratios. Freight locomotives are designed to pull heavy trains and even more important, get them started. Because of this they are geared (pinion gear on traction motor and axle gear) for tractive effort and starting force. Much like switching to low gear on a truck when getting started for added torque. Because of this; motors have RPM ratings. If you kept power applied on a motor geared for 70MPH MAS as speed increased the motor armature would swell and ultimately come apart destroying the motor and potentially locking the axle. Either way, major damage. So that's why you see MAS ratings on loco's. It's also why you may see NS loco's with 70MPH MAS despite NS not allowing speeds on their RR above 60, their loco's can still end up on other railroads who do run 70. Passenger loco's don't need the starting force and tractive effort freight locomotives do. Most passenger trains are not that heavy and acceleration and speed are more important. So they are instead geared for speed rather then overall pulling force. So sure, BNSF could order a 6 axle EMD or GE rated for 110MPH. The locomotive's diesel engine RPM and power output would remain unchanged. The gearing would be what allowed the increase in speed. Not anything you are doing with internal power output. However with such a gearing change the locomotive would drastically lose it's starting effort and overall tractive effort as a compromise for the higher speed. Freight railroads are happy with 60-70 as an MAS for intermodal. It's plenty fast and keeps wear and tear on everything much lower than going 80-90 would. Curves take a beating when 10,000+ tons ride into them at high speeds. It's why NS prefers 60MPH to limit wear even more. It's also why you never see passenger railroads even considering 6 axle power. More maintenance and more wear is not something railroads that are more concerned with speed want to deal with.

@@FFred-us9tw No the overspeed doesn't limit the power, it activates the brakes once an engine exceeds 73 mph, but the power is not fully distributed towards speed as it is pulling.

@@bossnaz7845 Read my first paragraph above again. I never said the Overspeed limits the power. You did. I said when a locomotive hits the overspeed limit, which varies by locomotive (GS ES series are mostly rated for 75, EMD's 70) the locomotive PCS opens and the locomotive drops it's power and the it goes into a Penalty application of the brakes. As for the power "not fully distributed towards speed as it's pulling", of course it's not. If it was the wheels would spin freely and you'd never start moving. The traction control systems in these locomotives are designed to only apply as much power as adhesion allows. If the wheels get good traction and hold it you will get the max power for that throttle position. But if you go straight to Notch 8 from a standstill on a heavy train you are will never get the full HP the locomotive is rated for. That's not how they work.

Looks like 69 MPH; the 79 MPH videos look slightly faster than this. Edit: Stupid me... I didn't see the description.

The speed on this division (and on ALL NS trackage) is 60 MPH max for intermodal. You will not see any NS intermodal trains going above 60 MPH on NS tracks. Don't listen to the buffs who insist through some sort of flawed logic that they are going faster.

@@FFred-us9tw Do they use speed control? If not, it is conceivable that they could be going a few mph over. I was pretty close just by using the ol' peepers to measure this train's speed, but that is not very remarkable at all given that I used to live in Mentmore, USA with a Class V ATSF trunk in my backyard (79 MPH IMs/coal units and 89 MPH Southwest Chief leaving downtown Gallup).

No zooming please. It's distracting. The train looks slower with long focal lengths, though it can be an interesting view in the distance. Suggest cutting from long to normal FL.

#NicholasLD YOU CANNOT BE THAT CLOSE TO THE TRAIN!! RAILROAD EMPLOYEES FIND IT ILLEGAL AND DANGEROUS! YOU COULD HAVE GOTTEN KNOCKED OVER BY THAT TRAIN!! THIS IS THE REAL POLICY BY ALL RAILROADS STAND BACK AT LEAST 10 OR 30 FEET TO PREVENT AN ACCIDENT OR ANY INJURIES. DO NOT STAND ON THE GRAVEL EITHER. MAKE SURE YOU ARE A SAFE DISTANCE AWAY FROM THE TRAIN AT ALL TIMES AND DO NOT FILM THAT CLOSE TO RAILROAD PROPERTY
