Railbus 772 007-1, door. When it was modernized in the early 1990s, it received red
buttons to request stops as in a bus and automatic door opening/closing (operated
with the green buttons). The door handle is still there, but now without function.
The door is folding to the left. And despite this, the railbus can still depart 
with open doors - after departure in Dürrröhrsdorf (line Pirna - Neustadt (Sachsen)) 
on 2001-02-16, I noticed that the driver forgot to close a door, so I closed it with 
the button .... Quite a difference to the complicated door control systems of modern 
trains!
Note also the grammatical error on the sign "Nicht öffnen[,] bevor der Wagen hält".
