Why do train engines idle so long?

Even when switchyard locomotives are not moving trains, their diesel engines are usually kept running. This is done to charge batteries, warm engine fluids and meet other operational needs. This can amount to several thousand hours of idling per locomotive each year.

Traditionally, railroads have kept their locomotives running continuously whenever temperatures dip below 40 degrees because the engines can become extremely difficult to restart. Trains also idle when crews change shifts. “Because of past practice and housekeeping issues, they tend to run all the time,” Downing said.

A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.

Once a train has been idle for over four hours, or if any cars were removed or added while stopped, regulations require crew to perform an air brake test prior to proceeding to the next destination, a process that can take several minutes.

Idling switchers use between 3 and Il gallons of fuel per hour depending on the ambient temperature. If a switcher idles 12 hours a day in warm weather and burns 3 gallons of fuel per hour, it would consume 36 gallons of fuel per day.

These can be as low as 200 revolutions per minute (RPM), in contrast to earlier locomotives which typically idled at 315 RPM. Many of the earlier units have been retrofitted with available low idle speed modifications to reduce idle RPM as much as possible, limiting noise and air emissions.

A sandbox is a container on most locomotives, multiple units and trams that holds sand, which is dropped on the rail in front of the driving wheels in wet and slippery conditions and on steep grades to improve traction.

motorists often try to beat the train at crossings and if it's a tie you lose. for this reason locomotive engineers are legally. required to blow their horns at crossings at least 15 seconds before they reach a crossing.

Have you ever thought why trains blow their horns so often and so loudly? The truth is that they have to. And the main reason for that is safety. Locomotive engineers are required to honk every now and then, which is written down in the regulations called the Final Rule on the Use of Locomotive Horns.

Yes, locomotive engines typically have a toilet, also known as a lavatory or restroom, for the use of the crew members who operate the train.

Using rail is the most environmentally friendly way to move freight over land. Railroads are roughly four times more fuel efficient than trucks.
