It's that time again! Ask me about trains.
What kind of maintenance do the rails themselves need? About how often do they need to be replaced, and do frequency or weight per wheel of trains have anything to do with this?
A guess based on a Google search suggests a rail lifespan anywhere between 5-99 years. Lightly used industrial spurs could easily have rails that are 90 years old or more, whereas a curved piece of track with high frequency, fast, heavy trains might only last 3-4 years. In terms of maintenance, rail grinding is used to keep to track smooth, and maintenance teams inspect the track periodically (obviously not enough in North America). If I recall correctly in Japan the Shinkansen tracks get inspected every night for safety and upkeep, a great way of keeping high-speed trains safe and fast.
When metros start/stop, I hear what sounds like gears shifting. Are there actually gears in the average metro? Take Berlin for example. I did some casual Googling and it doesn’t seem like they have gears. They do have several motors though. Maybe it’s motors turning on sequentially?
Sincerely, Guy who knows almost nothing about trains but knows some about cars
I love that inverter sound so much. Electric trains should sound like spaceships.
This fast-talking Brit has the answers, and it's pretty complicated. The short answer is that it uses variable-frequency inverters to accelerate, not gears, and those inverters make super cool sounds when that happens.
I am amazed by the mere existence of such a specific and in-depth video on this question. Going to give it a watch. Thank you!
There are entire channels on Youtube dedicated to inverter sounds. If you want to hear more trains sound like spaceships, look up GTO-VVVF for the good stuff.
Cabeese were abolished in the 1980s by FRED, or Flashing Rear End Device, a device that records various data about the train. It also has a little flashing light of course. I feel like this is adequate if you have like 30 car trains but with the multi-mile long trains today I do think there should be a caboose requirement for trains over a certain length. I wonder if the East Palestine derailment might have been prevented if there was a caboose on the train to watch for smoky axles. Plus, two more people in an emergency.
Now that I think about it, a caboose probably wouldn't have been enough to stop the derailment because the train was so long, but it might have helped a little.
How hard is it to produce a train?
- What kind of geological reserves are needed?
- What kind of assets/capital in machines etc. infrastructure are needed?
- What amount of knowledge/patents is/are needed?
uh uh uhhhhh IDK
What I can say is that American manufacturers are not doing well because the buy-American policy combined with the lack of rolling stock being built means that there are several cases where an entire locomotive plant is built that only produces a few trains and is then shut down again, because most of the domestic rail manufacturers have gone out of business (RIP the Budd Company).
AES countries also give us a hint into how they might work. Cuba does not seem to be able to build new rolling stock thanks to the embargo, and struggles to maintain its railway network. Basically all of the trains are either pre-revolution or an eclectic mix of old rolling stock from around the world. The DPRK does produce its own subway trains but they look a little outdated. China, with its vast industry and large amounts of steel, excels at building trains and has built many over the past decade.
Edit: Actually I take that comment about the Pyongyang Metro back. The new trains look very comfortable on the inside, are clean, modern, seem to have modern inverter propulsion, and most importantly have nice cushy seats, something lacking on Chinese metros.

This and Mali/Angola are why I thought about what is needed to set up train (and maybe rail) production.
If you had to marry a train which train would it be and why?
You know I was thinking I would go for the PRR S1 because it's sexy, but then I though that what I really want in a long-term relationship is low maintenance so I'm going with the EMD AEM-7 for high reliability, clean electricity power, and good speed for that nice whooshing action as it passes by. You think you want that sexy train, but what you really want is a stable marriage that always makes the both of you happy consistently.
AEM-7spouse is bound to ask that I take down the S1 pinup that I have on my wall though
They were always cool. In terms of usage, probably making them relevant to war again. Hopefully that never comes to pass unless in class war.
The loading gauge is too small. British trains have a very small loading gauge (the space a train can fit in) so tunnels and bridges wouldn't allow it. They did try to fit the trains in the loading gauge anyway, leading to a strange train in the 40s that had many issues and never went beyond two train prototypes
Loading gauges have been heightened on several US railways to accommodate double-stack container trains, so it's certainly not impossible. However I don't think the neoliberal economics line up for Britain anytime soon, and even under socialist economics it has questionable value.
Just to add insult to injury, here's an entire wikipedia article dedicated to just how wrong you are https://en.wikipedia.org/wiki/Bilevel_rail_car 😈
First off I love the profile pic, wasn't that the anti-whale article guy?
Secondly best train is subjective (obviously). I can't really say, but one thing I do kinda want to talk about are trains ahead of their time. The Rocket achieved 30mph in 1829 and was cutting-edge at the time.
Also of note was the AEG Experimental three-phase railcar which achieved 130mph in 1903, only 100 years after Trevithick's first steam locomotive in 1803. 210km/h is what the Shinkansen was scheduled at in the 60s, and contemporary trains rarely went above 80mph on the fastest expresses.
There's so many good options but one that came to mind was the Minneapolis Airport C concourse people mover, because it has cable-hauled automated trains with a passing loop and a bizarre determination to only have doors on one side of the train, so there are two platforms for the center station on the same side dedicated to different directions.

Yes, now do every tram/city car that ever served in Pittsburg.
Battery electric is dumb, don't do that ever, unless you are gigachad enough to do it with lead-acid batteries on branch lines only. Overhead is objectively the best form of electrification, although I like the aesthetics of third rail better. Third rail can only be DC, as AC is too dangerous, but overhead wire can be DC or AC. One little detail I think should be in consideration for overhead electrification is putting the poles in between the two tracks so the scenic views don't get blocked.
Ok I got to go right now but keep asking questions and when I get back I'll try my best to answer
I don't really have a question, I just want to say electric-steam locomotives are the coolest and I want more of them, practicality be damned
How do those new chinese trains work that seem to not be touching the tracks?
What's your solution to the London Underground heat sink problem?
This one's not really a question but a plug. Did you know about the Soviet travelling film trains?
That's maglev technology that you see them using. Maglevs use electromagnets to levitate above the track and achieve high speeds.
The London Underground could really use some air conditioning both in stations and on trains. The proper solution to the problem I think would be to build more ventilation shafts to let out hot air. One of my favorite Youtube channels is Jago Hazzard, a Youtuber who makes short little videos about London trains. He's made a video on hot underground trains before.
I did know of the Soviet traveling film trains, they are cool as hell. Bring back doing literally everything with trains.
