Electric train engines operate all over the world. They transport travellers quickly and efficiently, and they are cleaner than the diesel locomotives that serve as their main competitors.
Model trains provide hours of entertainment for children and adults alike. The electric trains that make-up most HO sets work on the same principle as the modern lectric trains that transport passengers in the world's largest cities.
The larger passenger trains are in many ways just much larger versions than the HO and O scale trains that have been enjoyed by hobbyist for over one hundred years. While steam and diesel powered model trains are also available, focus will be kept on the electric engines that power most modern model train sets and real electric trains. Trains that operate solely on steam power are sadly not for indoor use.
How Most Model Trains Complete a Circuit
Most model locomotives use the track as an uncompleted circuit. Electrical current passes through the metal rails. When the locomotive engine is placed on the track, the circuit is completed and the motor generates the power needed to move the train. The operator controls the speed from an electrical power supply attached to the track. The would-be engineer controls the speed of the vehicle by adjusting the amount of power through the circuit.
Passenger Trains Operate on a Third Rail
Passenger trains and a few select model trains supply the power along a third rail. The generation of the electrical energy can be achieved by any number of methods, including nuclear and coal power. Most passenger trains are controlled by computer in a distant control. Such computer control centres would excessively raise the price for the hobby model railroad builder, but they help ensure the safety of the passengers and ensure that the trains arrive on time.
