What is the power supply for trams?

Most light rail or tram systems get their power from overhead catenary systems. Typical voltages range from 600V–750V DC, with more recent installations tending towards higher voltages. These voltages are lower than those used by traditional electrified railways, which use much higher AC voltages up to 25 kV.

Today, most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used.

Over the years various refinements have been made, such as replacement of series-parallel controllers with modern solid state control systems, and the substitution of trolley poles with pantographs. However, in the majority of tramways the electricity supply is still between 600 and 750 volts DC [1].

Alstom's APS ground-level power supply system is a proven alternative with equivalent performance which is currently operating in seven cities on three continents and offers safe, reliable power to trams whether in short catenary-free sections or along the entire line.

Tramlink in line with most tramways is powered at a nominal 750 vdc. Peak Power Consumption is 1MW in any section.

MORE DETAILS

DC voltages between 600 V and 800 V are used by most tramways, trolleybus networks and underground (subway) systems as the traction motors accept this voltage without the weight of an on-board transformer.

An extensive tram network covered large parts of London for several decades during the first half of the twentieth century. By the 1950s, however, trams were seen as old fashioned and were gradually phased out to create more room for buses and cars.

Trams running on solar power A unique connection between the eco solar park 't Oor in the Dutch city The Hague and the power grid of regional operator HTM allows trams of Randstadrail 3 and 4 to run on solar power. There are 4,700 solar panels installed, producing over 1.4 Gigawatt hours per year for the trams.

Trams draw their power from a single overhead wire at about 500 to 750 V DC. Trolleybuses draw from two overhead wires at a similar voltage, and at least one of the trolleybus wires must be insulated from tram wires.

Trams cannot go around obstacles, they don't mix well with bikes, they take up too much space and “they cost a fortune,” as Washington DC can tell you.

The Environmental Reasons For Trams And Trains In Europe Rail systems are so popular in Europe because they can get loads of passengers to their respective destinations en masse — with much less of an impact on the environment.

MORE DETAILS

DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.

MORE DETAILS

The Metrolink system can achieve low pollution levels because the trams are powered by electricity produced from modern, cleaner, greener sources – around 70% of a tram's power comes from wind or solar / photovoltaic sources as does the power on stop.

If there are only two rails on the line (the ones the trains wheels run on) and there are no overhead lines then, yes, you're correct that the line isn't electrified. There is a very small electric current running through the running rails, used for signalling.
