i’m gonna tweak out after making tunnels
the shape tracks are just so cooked in some plaes, idk who designed this IRL (they probably had a reason to do it like this, but i wasn’t alive during those times lol)

fully connected Kálvin tér > Kőbánya-Kispest (the other direction)

quickly made some cube-like tunnels for M3 in blender

i’ll have to fill in the gaps in some places, the 2nd image shows that only one half of the tunnel is there (there will be a separate floor and ceiling “tunnel” that connects the left and right pieces)

the last image is the completed line Kőbánya-Kispest <-> Kálvin tér (gotta test track continuity later)

the 3rd image shows a goofy ahh descent as i was beginning to adjust elevation

polished up some stations, double platform stations now have signs

also connected the two platforms of KöKi
