One of the toughest carriage sections I've found is where your platform jumping rotating blocks , dodging mines etc and a pirate ships targeting and shooting through the train at you. It can be pretty frustrating.
A little trick I think I've found is that you can avoid being targeted by the ship by using a character that has a stealth ability. E.g. Stealth elf , stink bomb
Just use their stealth abilities constantly in between jumping platforms and the ship doesn't seem to be able to target you
