Made a third version, been playing a wipe now that its updated! And been having a ton of fun hitting those tunnels and riding the rails, I really like the Red variant of cart i reckon It matches the tunnel dwellers outfit, doors and architecture better than the yellow cart. Both are cool but the red ones faster :P I also updated the train symbol to match the tram sign. The new variant i think hits any parts of the style I missed in the initial too hope you all like it. its last one i promise AKA no lights on version of red door unless really requested I don't really like them on to begin with.

Work cart wreckage in the tunnel leaves a good amount of bits and bobs to use, why not use a broken cart to make a sheet door? good strong stuff init! it don’t matter if you are a tunnel dweller, train spotter or avid recycler this is the door for you! i’m so hyped for the work cart update!!! and got just the door for it.

yellow cart from pre update:
