As a children's railway is called a portable, electrically operated normally as railway ride for children at local fairs.
The power supply is depending on the system with 12 or 24 volts DC or 38 volts AC, mostly above the rails. Children railways should be the only personenbefördernden webs which are supplied with current via the running rails nowadays.
Because the distances often are very short (typically more than 50 meters) and the rails have a large cross section, transmission losses are small, despite the high currents. If the transmission losses still be too high, a second power supply, either via a route along the laid cable or via a second " sub-station ".
The vehicles for DC operation are often like old trams via series resistors controlled with a tap changer. On some vehicles, there is only a simple on - off switch or as the only way of speed regulation, the ability to switch the motors in series or parallel. In vehicles for AC operation, the voltage is transformed up on board to about 70 volts, and then supplied to the motors. Some newer children railways for AC operation, use a phase control using thyristors.
