OpenSite Designer for Railway Stations?

Came across this planning application for a small railway station outside Torbay, UK.

The design is pretty modest but what was intriguing is the sloping terrain that the station has to fit into. It reminded me of OpenSite's cut-fill optimisation functions.

Just wondering if anyone has used OpenSite for railway jobs. I imagine that it would be good to understand if tweaking the track alignment can reduce the earthworks costs, which is a big carbon emitter.

Looking at the station design, the roadway, parking, ramps and fencing all have react to the terrain. I.e. carve into or bank onto the existing terrain. This would be quite labourious to do manually. A good opportunity for OpenSite Designers tool set to shine?

You almost want to be able to slide the station platforms along the track alignment in 5m intervals and compare the excavation costs.... :-)
