Last vacation I visited the Train de l'Ardeche. A hertage railway.
Most of the photo's are from there.
The locking mechanism for the turnrable was intersting. When the lever (hold by the man with the handgloves in the previous photo) was above the flat plate they dropped it. It hit the block onthe other flat plate (seen on the next photo) and that stopped the turning. It also aligned the table in the correct position.
I think this could be a good idea for a model turntable, also handpowered of course.
Some very small bogie trucks. It think it is for transport at the station area only. Despite the small size the wheels are still kinda spoked.
