Mini trains that can run on regular rails! Ik little logistics exists but it's so finicky cause the ai is full stupid and doesn't follow checkpoint order properly. Using train schedual logistics and train station direction would be sooooooo much help!
#mini trains
indigo thunder

Honestly the closest you'll get to this is probably just using narrow gauge rails and even then
uneven dagger
Or minecart contraptions, I guess
upbeat igloo
Or maybe try Little logistics mod
