The other style of steam tram had the steam engine in the body of the tram, referred to as a tram engine (UK) or steam dummy (US). An aerial tramway consists of one or two fixed cables (called track cables), one loop of cable (called a haulage rope), and two passenger cabins. The Saint Petersburg Tram Company[163] produces highly detailed polyurethane non-powered O Scale models from around the world which can easily be powered by trucks from vendors like Q-Car.

An important advantage of standard gauge is that standard railway maintenance equipment can be used on it, rather than custom-built machinery. If the full traction voltage is applied to the motors from rest, they Horse-drawn trams still operate on the 1876-built Douglas Bay Horse Tramway in the Isle of Man, and at the 1894-built horse tram at Victor Harbor in South Australia.

Electric trams are either powered by two or four electric motors which sit underneath the tram between the wheels.

But sometimes you can’t – see above – and when that happens you’re stuffed.

New 'trackless trams', which take innovations from high speed rail and put them in a bus, have changed his mind. When the rail network is not electrified, the train must use its own energy for propulsion. The most intensively used junction in any tram network is the Lazarská x Spálená junction in Prague with appx. pumping up the air reservoir when it falls below 60 psi, switching off A steam tram ran from 1881, and electrification followed in 1897.

The first trams in Australia opened in 1860 in Sydney. Another motive system for trams was the cable car, which was pulled along a fixed track by a moving steel cable. The San Francisco cable cars, though significantly reduced in number, continue to perform a regular transportation function, in addition to being a well-known tourist attraction.
