Mixed refuel station
The stations for 1 or 2 locomotives will provide your trains with the best 3 same stacks of quality rocket fuel or nuclear fuel available. It currently selects nuclear fuel over rocket fuel - and ascending quality. Any left-over fuel will be removed when the train enters the station.
The train station is setup to serve only if it has at least 3 full stacks of fuel - no mixes. If a station gets stuck - unable to serve for more than 5 minutes an alarm will be raised.
Various indicators try to indicate its current state - e.g. unloading, loading, which fuel has at least 3 stacks and which fuel it determines the best.
It requires the mod Inventory sensor to function - as individual rocket fuel cannot be detected within vanilla game boundaries.
Advantages:
- easy refueling of trains
- lots of status effects
disadvantages:
- requires a mod
- refueling condition is limited to <=1 - as rocket fuel and nuclear fuel have so different stack sizes. Meaning there is a risk that your train might run out of fuel to the station with rocket fuel. You can increase the limit to 10 if you do not use nuclear fuel.
