What voltage did trolley buses run on?
Power is most commonly supplied as 600-volt direct current, but there are exceptions.
Are trolleys AC or DC?
As I understand, streetcar (and trolley bus) power is DC current. But DC is very poorly transmitted over distances, meaning that the trolley wire would quickly lose sufficient voltage to power the vehicles as distance increases from the source.

“The main reasons for getting rid of the trolley buses were the lack of flexibility with routes and the lower running costs of diesel. … “At the same time advances in battery technology now mean that trolley buses can run away from their overhead wires for considerable distances if required.
Which motor is used in trolley bus?
The traction motors may be compound or series motors. Compound traction motors are used in Soviet trolleybuses; such motors operate well both as a traction system and as a generator. Compound motors are suitable for regenerative braking, in which electrical energy is returned to the contact system.
How fast can a trolley go?
New light rail systems average 17.2 miles per hour, and the fastest at-grade system operates at 18.2 miles per hour. This same “slow speed” Old Wives’ Tale is picked up and re-articulated in a variety of forms by anti-rail zealots across the country.
How do trolleys get power?
