I used these train BPs with Cybersyn to get as far as Production science (still ongoing). I currently run 2000+ stations on 160 trains.
I used the 16x10 chunk block blueprint from the start of the game so that I wouldn't have to move parts of the factory later.
2pm corner block (NE corner) can be rotated to serve as a SW corner. 8pm corner (NW) can also serve as a SE corner.
The C and S stack stations can support two 1-1 trains at a time. By default the stations themselves are set to limit 1.
"Wet unload" will unload one filtered liquid. Use "Wet unload another" to add a second fluid at the same station, which will also make sure the wire is not forgotten.
