Having the option to run one (or multiple (maybe lvl1/2/3 capable)) Conveyor lines near ground level through train platform that have a certain length without having to build all the way over a platform would be pretty neat.
The idea would be something like the empty platform, serving the same purpose within stations, only with adjustable conveyor I/Os on either side, as said, maybe even one extra per level.
This way people could run a train through a factory easier, without having the trouble of building and rebuilding kilometers of conveyor lines up and down and up and down again.
Just a small suggestion,
Thanks for reading and have a nice day!
