I would like to have more control on what my fleet looks like. Instead of a white roof and 1 type colour body work, it would be great if there where patterns for our vehicles and at least 2 colours to choose for the body of our vehicles. Also when I start my metro network passenger intake is low, so it would be great if we could customise the trains example min of 3 carriages (For the very beginning of a of line or unpopular lines) to the Max of 6 carriages for the popular lines
