HELLO
YOUR ANSWER IS
We all have observed many times that diesel locomotives are kept idle in the yards and also when waiting for too long in the yards or station especially for goods train. Loco pilots can switch off the diesel engine and save fuel instead of running in idle condition but they don't do.
Here are some technical reasons -
1- The brake pipe pressure reduces due to the leakages and it takes longer time to build up working pressure .it is very curcial when waiting for the signal on the grade.
2- A proper checklist have to followed to recrank the engine. It takes 10-15 min to do so when starting after a long shutdown.
3- To keep the compressor running , engine must not be switched off as it is coupled with the engine.
4- As the diesel engine contains usually 16 cylinders (each cylinder has capacity of 200 HP) and are also big in size , so it is quite difficult to achieve ignition temperature.There are many auxiliary components running so if one fails or some technical parameter changes may cause problem in starting.
