SS tram no. 70 from 1913 with trailer 647 is driven in Oslo on Saturday 10th April 2010. We watch the ride from Biermanns gate to Olaf Ryes plass downhill through Birkelunden.
Note that the driver is handling 750 Volts directly in the controller. When turning the controller handle clockwise from nill, he's applying power. When turning the handle counter-clockwise, he's applying brake notches stepwise. He's not using the last brake notch as it applies the 750 Volts magnetic track brakes, only used in an emergency. We can also listen to the use of the foot bell to warn other people around the tram.
Giving the killing 750V directly through the controller seems to be the most unsafe way of controlling trams. But, this is 1913... Anyway - the driver does a good job... and what is the black wheel on the right hand side of the cab for?

@peteru18 It's perfectly safe in the hands of a skilled driver, but dangerous in the hands of a driver only used to modern controls. The black wheel on the right hand side of the driver is the handbrake, which is applied to halt the tram when the electric brake stops funtioning at very low speed.
