Our employees must step from the ground to the inside of a train, a height of approximately two feet with the use of a handrail located inside the train. They pull themselves up into the train. In the shop, we have obtained ramps for them to access the trains. In the field this is not feasible. nor are ladders, stools etc.
I am looking for ergonomic tips and suggestions on how to physically (without devices) protect their knees when pulling themselves up into a train. I have suggested sitting on the train edge and clambering on this way. Any other ideas?
