Let's get rid of the bike fag infestation. Imma post pics from work. Pic related - did a site visit to a station built in 1926 and they wanted to demolish the station and upgrade it. Look at that antique interlocks!
Thermit welding bitches !
Is it a train ? Is it a truck ? No ! It's a Unimog !
Ballast sucks. Concrete rulez.

Steam trains are dead or in museums. They're fun, but let's stop referring to all trains as museum relics. They are outdated and pollute the environment.

I meant train engineers in general >_>
Or even engineers working on tracks (like me)
>all these black people
are you from SA too?
Not that i mind the pictures, but how do you imagine this will get rid of the bike fags?

>You need a tamper on it nearly every month.
Given the re-bar underneath it, imma gonna guess they're pouring a slab right under & around those sleepers. Ain't nobody tamping it.
Also glued ballast.

Yeah it's a metro so maximum tonne/axle probably 16-20?
Anyways we mostly flashbutt our short rails but thermit weld every long welded rails. Will check out gas welding

Even 16 for a subway is heavy. You're looking at like 6-8 unloaded for some systems (maybe 9-12 full under non Japanese conditions).

You can do it in the field, but as you see the equipment is kind of bulky. You can't get the weld done in some tricky places like switches.
It's a very strong weld and the kind they make in the factory. That's how they manufacture those big 1400 ft. sticks of rail.
Too ridged of a foundation will cause structural failure. The whole thing has to float and remain flexible. Henry Ford experimented with concrete ties on a ridged base when he was in control of the Detroit Toledo and Ironton railroad. Didn't work back then. Need to see completed track photos.

This.
Wooden ties are great not just because they're cheap, but they're also flexible while still holding gauge.
People think of track as a fixed stucture, but it's actually a very fluid, almost living, thing.

That's pretty interesting.

never knew nespresso machines used to look like that
