How are train engines cooled?

A locomotive radiator system primarily cools air, water, and oil. The air is used in the combustion process; the water for cooling the engine and turbo (if equipped); and oil for lubricating the engine components. Electro-Motive Diesel and General Electric differ in radiator system design.

Are train engines air conditioned?

Modern locomotives are air conditioned but many older ones are not. Individual freight cars may be refrigerated or heated, depending on the needs of what they carry. Cars that need temperature control have self-contained refrigeration or heating units.

Can a train engine overheat?

The last factor to consider is weight — if the locomotive is too heavy, no matter how good the mechanism or motor, the motor will overheat.

How does a locomotive diesel engine work?

The ignition of diesel fuel pushes pistons connected to an electric generator. The resulting electricity powers motors connected to the wheels of the locomotive. A “diesel” internal combustion engine uses the heat generated from the compression of air during the upward cycles of the stroke to ignite the fuel.

Why do train engines idle?

Why Do Locomotives Idle? Train engines generate thousands of horsepower and take an hour or more to warm up before they can start pulling rail cars. Engines are also kept running to provide air conditioning or heat for the crew, which may be aboard even if the train is idling in a yard.

How are locomotives powered?

How do locomotives cool the engine?

The engine is cooled by radiators and fans mounted above the engine. Cool air is also ducted to the traction motors for cooling. The locomotive also has electrical braking where by the traction motors become generators causing the wheels to produce work causing retardation of movement of the train.

How does a trains engine work?

Trains use a diesel engine that drive a generator attached directly to it which manufactures electric current to operate motors mounted on each axel for propulsion. The current is directed differently through the traction motor for reverse operation as the engine and generator always turn in the same direction.

How does an engine cool itself?

Air, water and oil directly cool an engine. In most engines, most of the heat goes to water, about 10\% goes to oil, and a few percent goes to air directly. In most engines, the water is then cooled by air, and the oil is cooled by air or the water.

How do internal combustion locomotives work?

Internal combustion locomotives use an internal combustion engine, connected to the driving wheels by a transmission. Typically they keep the engine running at a near-constant speed whether the locomotive is stationary or moving.
