A complete bi-level trainset from the former east german Reichsbahn at the Magdeburg central station.
The locomotive is a BR143.
Those old DR bi-level cars were of course refurbished several times.
The last stage was a new cab design to match the current generation of bi-level cars
The original cabs had a flat front: [link]
They also seem to have a lot issues with the front destination indicators on those, no train I saw had them working properly.
