I disagree with the Locomotive removal.
It could be made either a bit more fuel efficient, more supply efficient or carry more ships, the fact that is stuck at burn 8 is already a big disadvantage (already in "old" SS+ having 4 Oxen was always better than a single Locomotive in all fronts but fleet space)
Also the supply/month cap is a bit iffy to me, wouldn't a fleet that is so big that it is economically unfeasible to sustain be already a limit (ie: you're burning through more supplies and fuel than you can make money)?
I however want the Parrot now that i see it, how difficult would it be to bring it back?
