Technical details

The ABDeh 4/10 class is part of the Stadler GTW family of articulated railcars. It has an aluminium frame, semi panoramic low floor bodies, and air suspension. The first class compartment has 47 seats, and there are 141 second class seats.

Service history

The class is used for regional train services on the Brig–Visp–Zermatt line.

gollark: And the government funding means we still get that, so it seems fine.
gollark: Intel and TSMC and whoever else are producing new semiconductor manufacturing processes, tech companies frequently work on new somewhat crazy ideas, pharmaceuticals companies do drug discovery.
gollark: ... companies have research departments, you know, for stuff which will eventually be profitable.
gollark: They're genetically programmed that way. They have the same genomes or something.
gollark: An important recentish discovery: blue LEDs. Those require exotic materials of some kind, as far as I know, and like all semiconductory stuff large amounts of complex machinery to produce them.
