I think London used the TIM right up to the end of conductors. Before the Setright Speed, Midland Red used a machine with buttons on the top for the different fares and the conductor then moved a lever across the front of the machine to print and issue the tickets. No idea what that was called. I am talking about 1950 when my mother used to ask for a penny ha'penny and a penny child's to take me home from school. Couldn't understand why half fare wasn't three farthings!
