Trams And Trolley Buses
I watched the programme on trams the other night, and some old questions stirred in my mind.
Sheffield kept its trams longer than most places, but did it ever have trolley buses, or even try them out?
Were trams and trolley buses used alongside each other anywhere, and if so did they use the same power lines?
I understand trolley buses were more manouverable than trams, but was their main advantage that they didn't need tracks laying?
And one that I've wondered about for
From memory I think that there was only a main circuit breaker at one end of the tram and if the driver was using that cab then I think he could have re-set the thing himself. There would be no point in having two in series as either or both would trip on an overload. Perhaps there were two and only one closed at a time to set the driving end.
Normally the breaker would only trip if he was a bit too quick swinging the controller handle across the notches.
