Here's a replica of a very early railway car (1829). Its design owes much to the stagecoach -- the only mass transport device known at that time. It ran on the Liverpool-Manchester line, the first intercity steam passenger line.
Below is the seat used by the guard. One per train in a green uniform.
The steps below were required as elevated train platforms were not created until later -- so passengers had to climb from the ground.
The replica was built in 1930 to commemorate the centenary of the Liverpool-Manchester Railway.
