Mega Vehicle Underpass

Mega Vehicle Underpass
This design was originally inspired by the Calen version.
However, after trying it out, I felt like the setup took way too many steps. So, I raised the tracks just a little bit. It might sacrifice a tiny bit of train speed, but it makes building it a total breeze! All you need to do is plop it down (just remember to snap it to the terrain grid) and dig out a tunnel.

The lowest point in the middle is 3 terrain tiles wide, meaning it can actually fit up to a 6-track railway. I mainly designed it this way to buffer any alignment errors with existing 4-track lines, especially since those older tracks probably weren't built to snap perfectly to the grid anyway!
