Kassel streetcar number 218 was used in Amsterdam for a while as a heritage tram, but then it was brought over here and renovated by the HSM.
The bulky vehicle on the left-hand side was used on the Esslingen-Nellingen-Denkendorf (END) interurban tramway line, which was closed in 1978. Next to it: a tower car for overhead maintenance works, equipped with a diesel generator, so that it can move without "live wire" (originally Kassel 722, built in 1898 and rebuilt in 1965).
A 4-axle Talbot tramcar built for the Aachen system, which was closed in 1974.
A "two rooms and a bath"-type articulated car from Munich...
.. built onto two 3-axle chassis. The company Rathgeber has built only two such trams for the bavarian capital as an experiment.
A 1912 coach (half of a train to be exact - a trailer) of the Wuppertal suspended railway.
There were plenty of streetcars just standing around and waiting for better times.
A 1950 "Aufbauwagen" built for Hannover by D▄WAG. This was one of the vehicles that participated on the tram parade held in the afternoon.
Trams everywhere. The blue cars in the middle are type M/m trams (motor and trailer) from Munich, and behind it...
... there was this D▄WAG "Breitraumwagen" (=wide-bodied car) from Hannover. It was interesting because of...
... the widening "love handles" with folding stairs at the doors. These cars were rebuilt so they can be used on the subway tram lines with high platforms and normal lines with low platforms. I understand this wasn't really successful, and the cars were quickly nick-named "window-box".
The first "Grossraumwagen"-trailer ever built.
D▄WAG heaven: in the middle in the back: a classic D▄WAG TW4 "Grossraumwagen" from 1955. To the left-hand side: a six-axle GT6 with a four-axle trailer. On the left-hand side in the front: another 4-axle "Grossraumwagen" rebuilt as a works car.
The articulated GT6 was the base of a whole variety of trams in and around Europe.
Also a "classic" is this D▄WAG, originally built for Hannover's line 11 to Hildesheim in a bidirectional manner with doors on both sides. After the service was abandoned, it was converted to a unidirectional vehicle, but the color scheme was restored by musuem members recently.
Another "driving school" tram: a bidirectional D▄WAG GT4 from DŘsseldorf.
A Westwaggon 3-axle car from Bremerhaven, a city which had a tram system until 1982.
"Sisters" of this 1964 Stuttgart "two rooms and a bath" tram can still be seen in Stuttgart as works cars.
This might look like an average CKD Tatra T4D...
... but its an odd one: it has driver's cabs on both ends! It was used like this in Magdeburg.
A "Gothawagen" works car from Postdam...
... towing this wagon, which was built onto Tatra (PCC) trucks in Magdeburg.
A couple of buses - like this "one-and-a-half-decker" were also on display.
A look from the back of the museum yard, where the museum circle line leaves the visitor's area.
