B4Ctom1 posted:watching this makes me queezy This is without question the dumbest thing I have ever seen someone do in YouTube video. I'm betting he crawled under when the train was moving more slowly but lost his nerve when he went to crawl out. By the time this guy started telling him he could make it he was probably so high on adrenalin he wasn't thinking straight. Saying he should have waited seems obvious but if there was a pusher (unlikely on an intermodal but possible) or a piece of low hanging air line or something he would have almost certainly been killed.

This started an argument on IRC. Without mains power, could the train apply dynamic brakes? My argument was that they'd need live power to drive the fans to cool the resistor banks.

But surely they'd design it to take account of such an obvious issue? Dealing with power failure in an electric train has to be in the specs somewhere?

Modern electric MUs have two circuits - High voltage (600v, or whatever the wire/third rail is powered at), and low voltage. The low voltage circuit is fed through an inverter (or sometimes a motor-generator) coming off the high voltage circuit and varies depending on the car's design. In the cars I work on, it's usually between 32v and 40vDC. What the low-voltage inverter (or M-G) does is feed a bank of batteries under the car, which themselves supply the power for non-propulsion systems within the car. The purpose of having the low-V circuit tied in with batteries is to give the operator control when the high-V has no electricity in it, for a short while after the feed from the high-V circuit stops. This is accomplished by powering the propulsion control system with low voltage, but the actual motors run off of whatever voltage the wire is. Basically everything in the control stand on an EMU is low-voltage (which is the best way to do it anyway, because in the old days, with hi-V control stands, operators would periodically get "bit" by line voltage, via frayed wiring). bytebark fucked around with this message at 06:28 on Oct 3, 2012 |

The pantograph arm broke off the top of a LRT train as I was riding on it a few years ago (the "U2" style listed here). After the loud smashing sound and loss of lights in our car, the operator hit the brakes and stopped just after a major level crossing. Braking seemed normal, except perhaps the other 2 cars were the ones doing all the work. Public transit authority had absolutely no idea what was going on and took forever to get us onto emergency buses and on our way from there - ended up late to a final exam as a result. A few weeks later it happened again with a different train. Seat Safety Switch fucked around with this message at 06:29 on Oct 3, 2012 |

Cooling of the resistor stack becomes moot. I'm certain that electric trains still use pneumatic brakes, so stopping the trainset is independent of electical supply.

From what I have seen transporting the new Metro North cars from Lincoln NE to points east, they still use regular old air brakes. Plus the main air tank still holds air for some time, so there is redundancy.

ijustam posted:What a mess. How do they clean that up? Just... pick them up with a crane, put em back on the rails and hope they move again? They put them back on the rails, check to see that they roll, and then gently, using another locomotive, haul them someplace as nearby as possible, where people can fiddle and inspect all over them. After that they are sometimes put into another train and hauled dead, other times they load them onto specially made cars to be hauled like lading. example

gently caress me, man, I'm amazed that I haven't found this thread already. I've worked for two railroads (Dallas, TX and Williams, AZ), and I absolutely love these machines. As someone who has operated the old F40s several times, I can safely say that all the rumors you hear about how awesome they are are understated. They're better when they're left in the original EMD specs.

The only reason I know about this thread is because B4Ctom1's post about the derailment/collision a few pages ago was recently linked in the SA Quotes thread a while back. Anyway I was idly browsing imgur tonight and saw this, and I thought this might be the one place that appreciates it.

Doesn't Tri-Rail operate F40Cs too? I remember riding it when they still had their green and white liveries instead of that Palm Beach photo wrap thing they have going now. It looks like the SunRail service for the farther north areas of Florida is using the same push-pull system too.

It looks like the SunRail service for the farther north areas of Florida is using the same push-pull system too. Tri-Rail has some funny F40PH copy (built by Morrison-Knudsen), which appears to be comprised of F45 parts grafted onto a GP40 frame. So it shares the same cab as an F40C, but isn't a six-axle locomotive. Until they were mothballed a couple weeks ago, Metra's last two F40Cs were the only six-axle passenger units still in regular service in the lower 48.

ijustam posted:Is that why Amtrak seems to always have 2 locomotives on long-distance routes? One for moving power and another for HEP? I'm sure HEP is part of it. Running HEP sets the engine of a Genesis locomotive to 900 RPM and doesn't allow it higher or lower (cutting maximum power output by 500kW) and then can take 10-30% of the reduced power output to feed the train cars. Even still I think that has more to do with needing the extra power from the second engine to give reasonable acceleration out of stations and maintain 50-80mph speeds up grades. Some long distance routes like the Texas Eagle run a single locomotive but it is a pretty darn flat route. From when I lived in Virginia you could certainly tell that the Crescent and Cardinal would pull out of the station much faster than the Northeast Regional and VRE. The things you notice when waiting for the drat Metro to finally show up... I also read somewhere that CSX requires Amtrak to run two engines on the long routes so that if one craps itself the train can still proceed. That could be BS though.

Amtrak runs quite a few trains on CSX's Albany Division, but the only one I've seen with two engines is #48 running between NYC, Albany & Chicago. The regional trains running between NYC and Toronto, Albany & Boston only run a single engine, though they're only pulling about half the cars of #48. A regional breaking down on the main would pose just as big a headache as a long-haul, so I don't think it could be that. Brother Jonathan posted:Ah, CSX.
