They were called cattle docks, more commonly in England. England is a strange place. They have MPDs, like we did, but they are loco sheds, not railcars on the Larne line.
They also have loco depots, which are also loco sheds.
They have DMUs instead of railcars.
MPDs and DMUs are both railcars. They aren't aware of this.
They have signal boxes instead of signal cabins.
Everything is narrow gauge.
They call carriages TSOs, GHSs, BSKs, JHBs (well, maybe not that;) KSX, NHG, HTR, GGT... or whatever; instead of "open thirds", "corridor seconds", "Mk 1 standards" and "dining cars"....
and the innards of what they call a snack car is to us, a dining car (or maybe it's vice versa...)!
But, diversity adds interest to our rainy world, doesn't it...
