The track may be, but any tunnelling doesn't have to be, although the more precise it is the less jiggering and time spent actually aligning the track for the railway and desired tolerances. Same goes for the tunnels for this proposed accelerator. Doesn't matter if those tunnels are curved or straight.
Granted, with this accelerator (whether it be for leptons or railroad cars), they're not going to have Maintenance Of Way equipment come down and lift up the accelerator tubes, shove some new ballast and ties under it, and then tamp it down to the point it meets desired tolerances, like they do with normal railroad tracks.
