This original device lets trains go back without the necessity to change the engine from the top to the bottom of the train. It is a folding chair which is placed in the last hook, in the bottom of the train. The worker sitting in the seat handles the train brakes. Unless the rail worker does not push the pedal, the train does not go on.

So this action is important when there is any problem with the worker. If he falls to the railroad track, the train stops immediately. The small and light chair has a seat belt, a light and a whistle that both run on train compressed air. You can setup the device very fast, in about one minute.
