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 long does a train engine last?

Although commonly called “diesels,” the locomotives actually are electrically driven. The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive’s axles.

Why are diesel locomotives not shut down during a train journey?

How does a diesel train engine work?

A train’s diesel engine is a large unit, with around 16 cylinders. Diesel engines work on compression ignition and do not have an external ignition agent (spark plugs) as in petrol engines. So, in order to start a diesel engine, it has to attain its optimal working temperature by air-fuel compression alone.

Why do electric trains make smoke?

The amount of fuel-dependency and the maintenance issues which come along with diesel engines are the primary reason for this. Though electric trains are far more efficient than conventional diesel engines, some still love the nostalgia factor which comes with trains making smoke. Get The Best Drivespark Stories!
