Known as a transformer, this units role is to reduce high mains electricity to a safe voltage to use on your train set. Because of the low voltage used on your train set, you can put your hands across the track and not feel the electricity.
The transformer is a static device, which transform power from one AC circuit to another AC circuit at same frequency but having different characteristics. This variation of applied voltage can be carried out easily by the use of transformer along with tap changer provided in the locomotive.
Will Model Train tracks shock you?
Short answer at the top for those wondering; probably not! Since the train tracks are made of a longer length, the amount of electricity that passes through your body is very low when you accidentally touch the track while the model trains engine is powered on.
Prewar Lionel transformers can deliver up to 24 volts to accommodate large Standard Gauge trains; postwar Lionel transformers intended for the slightly smaller O gauge trains top out closer to 19 volts. Marx and American Flyer trains are intended to run on no more than about 15 volts.
Which motor is used for traction purpose?
Many single phase ac motors have been developed for traction purposes but only compensated series type commutator motor is found to be best suited for traction. Single phase induction motors have been abandoned as they are not capable of developing high starting torque.
EMCO manufactures Traction Power Transformers for the Indian Railways upto 42 MVA, 220 kV class. These transformers are single phase double limb wound construction and are specially designed and tested to withstand frequent short-circuits and overloading .Type:Single Phase A.C.

What happens if you stand on train tracks?
– Whenever youre on the track youre at risk of serious injury or death from trains and high voltage electricity. – Putting objects on the track (like stones or shopping trolleys) could cause an accident which may hurt or kill other people. Even a small object can derail a train.
How many volts are Lionel trains?
LIONEL Electric Trains operate on low voltage, usually 8 to 18 volts depending upon the locomotive and the number of cars used.
What are the requirements of traction motor?
General requirements of Traction motors / traction systemHigh starting torque. A traction motor must have high starting torque. Simple speed control – Suitable speed Torque Characteristics – Parallel Running – Overload Capacity – Size of Motor – high Efficiency. Braking –More items •Jul 21, 2014
Are diesel locomotives AC or DC?
In a diesel–electric locomotive, the diesel engine drives either an electrical DC generator (generally, less than 3,000 horsepower (2,200 kW) net for traction), or an electrical AC alternator-rectifier (generally 3,000 horsepower (2,200 kW) net or more for traction), the output of which provides power to the traction
The copper loss depends on the current (ampere) flows through the windings of the transformer while the iron loss depends on the voltage (volts). i.e., the rating of the transformer is in kVA.
Which motor is used in train?
DC motors 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.
Is sitting on railroad tracks illegal?
Trespassing onto railroad property, including tracks, bridges, buildings and signal towers, is illegal. Violators are subject to a citation for trespassing.
Why you shouldnt walk on train tracks?
Railroad tracks are private property, not public trails. Its illegal to walk on the tracks unless youre at a designated crossing. Trains cant stop quickly to avoid people or vehicles on the tracks. An optical illusion makes it hard to determine a trains distance from you - and its speed.
Is it illegal to trespass on railway?
Vandalism and trespass on the railway is reckless and causes delays. Trespassing on the railway is illegal and dangerous. Vandalism includes graffiti, litter, fly-tipping, overhead powerline and cable theft, and damage to fences, signs and tracks.
