Tram du Littoral,

SNCV SO motor car

N°. 10054

—  ligne 2

The photo shows the typical composition of those years. The older trailers were only used in last position when there was a lot of traffic. There were several reasons for this: most passengers used the first vehicles anyway (which were therefore more comfortable) and the last vehicle (which was the oldest) could therefore easily be uncoupled once the rush was over.
