What are the logistics required for transporting diesel with big mode operation or is there sufficient I the tanks to last a days operating cycle?

One assumes that as bi modes are generally replacing diesel stock they will be filled the same as the current stock is.

The exceptions will be the ‘emrgenct backup diesel engines’ on stock on lines that have been electric only but they should all share depots with bi mode or diesel stock anyway

assume you me bi-mode :)

my worry is with the trains coming off and back on electric power, the diesels will suffer from thermal stresses as they heat up and cool down. Going from cold to full output suddenly will kill engines. Ir will they have electric oil pumps and heaters to keep the engines a bit warm, and keep the turbos lubricated.

We all know about 'binary driving'* on HST's causing big ranges in engine/coolant temperature and resulting in thermal stress cracking.

Diesels are good for situations where they bang out the same output hour after hour continuously.

* this is the driver taking full power, then coasting. on off on off...

They have been designed with this in mind by people who design bi mode trains.
