Creating paths around L4D subwaytrack models

I’m guessing this will involve the arch tool but I can’t work it out, I’ve not used Hammer in years.

Basically trying to create a brush that follows the track around. Also I notice the track doesn’t end on a right angle, and the only way to fix this is by adding more tracks which makes it more of an S shape and therefore more complicated to create a path around. Any suggestions?

Arch tool, clip tool, vertex manipulation.

Yeah I figured it would involve the arch tool, but I can’t get the angles right.

Try using a protractor.

Thanks FP.
