S-Bahn Berlin Baureihe 875

N gauge model of a class 875 train from Berlin; the cab car part of the iconic "Stadtbahner", in its last incarnation from 1997. The corresponding powered car is also under construction, but I first want to check whether this works as it should.

Couplers, wheels and kingpins for the trucks are not included. I'll be using Micro-Trains products for all of them. It may also need some ballast to run perfectly.
