would be interesting, but remember than cannons of any kind on a train is not allowed
so small changes must be made to T-arty and tanks to do this

But yes, a vehicle hauler would be neat

trains already are able to haul other vehicles sans weapons

Just remove the tripwhirehooks from all the cannons and place them back after you arrived to your destination

You can haul other vehicles? Don't see that in the wiki and don't think its as easy as the landing craft hauls vehicles.

there's no such thing as actually hauling vehicles in movecraft due to the fact that unpiloted vehicles are just piles of blocks, which can be repiloted as anything they fit the size and block requirements of

build a train that has the right size and buffer blocks and it can have a tank or truck or any other craft type that is small enough attached to it anywhere in any way

it's a matter of creativity with movecraft stuff in getting things to work how you want them to

To add to Oreo's comment, this is an excerpt from the Movecraft page on our wiki:
"All connected and allowed blocks compose the ship that you are building."

Your craft doesn't care what you name the things on them, as long as they are within the requirements of the craft class you are building your craft as. In any case, if you can do this go for it, but I find hauling vehicles a weird use for Trains lol
