TL;DR

Train schedule option for Fuel (Any Locomotive / All Locomotive) to provided total fuel energy value (MJ) or total fuel item count independent of fuel type.

What?

Implantation of additional unsorted filters to provided total energy contained in locomotive (example: Mod: Inventory Sensor) and/or count of all contained fuel independent of type.

Why?

With the implementation train fuel interrupts and the vastly increased number of available fuels, their is no clean way (I have found) to implement the fuel depot interrupt (especially if you have different types of fuel depots or manually fill the train with a type of fuel other than the depot). If only the Fuel Parameter wild card is used, as soon as the first inventory fuel (which differs from that provided by the depot) drops below the threshold, the train will enter a continues loop of visiting the depot until it either depletes the said fuel or it is manually removed. This is also complicated by the changing of train fuel with research is unlocks (I never bother removing old fuel when I start using new).

I included my current solution below, but I have to manually replicate it for depot stations of different train formats (L_L, LL_, L__L, etc) and gets overly verbose as more types of fuels are handled. By introducing either option (item count or MJ) it becomes possible to interrupt the train only when it is actually low on fuel and not low on one type of fuel. I personally would love to see the implementation of total energy (and for other buildings).
