Why are train engines never turned off?

Trains, being large and heavy, need the optimal brake line pressure for its efficient stopping. For obvious reasons, loco pilots never compromise on brake line pressure. Another reason for not turning off diesel train engines, lies in the engine itself. A train’s diesel engine is a large unit, with around 16 cylinders.

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.

Why do diesel locomotives consume more fuel when idling than moving?

This is extremely difficult to do in a large diesel engine like as in a train. It is also interesting to know that while diesel locomotives are idling, fuel consumption is more than when the train is moving. This is because, while idling, the batteries are being charged, and the air compression is in operation.

Why don’t diesel train engines turn off?

Another reason for not turning off diesel train engines, lies in the engine itself. If the engine hasn’t been started since long (or, if the engine is cold), it takes quite an effort to restart it. Depending on the size and construction of the engine, it can take 10 to 20 minutes just to start it.

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!

Why are diesel locomotives disappearing from Indian Railways?

Diesel locomotives are slowly disappearing from the Indian Railway scene. The amount of fuel-dependency and the maintenance issues which come along with diesel engines are the primary reason for this.
