Food / Fuel Tips
Don’t make specialized food dishes. That just wastes food that could be used for eating.
Do invest in a Kitchen car and start making Soup. Being able to use 10 Food and 20 Herbs to make 20 Food is a good use for those Herbs.
You should also invest in upgrades for your Engine that improve its speed and fuel use. Increased speed means more ground covered, and better fuel efficiency means less fuel used. Having BOTH means you travel faster AND use less fuel at the same time.
Also, for the Stokers and Conductors, select Workers and Engineers who have the highest skill percentages; if they have over 100% that actually improves the operation of the train itself.
You gotta Min/Max a little.
