Here is a rail extension using highway corridor methods NO CANT approach. It works well enough just start with the super wizard to populate the alignment super table then make edits so the existing spirals have 100% of the super from the existing mainline track. For some reason some railways want the new siding extension to be 5-10 cm lower then the existing mainline. Other railways want the tracks to be level to each other = easier to plow snow etc.
The subassembly shoulderextendall does a excellent job of draining the sub grade and
keeping ballast 30 cm thick and thus ballast quantities down.
The approach used the Planar corridor lane method with tangent X fall at 0.00%
Take a look at the assembly's im no pro and
a corridor guru would most likely do it way different.
The track main line grade is 0.3%-0.4% east
to west so all that is left is some ditch design
to send water to the nearest gully / ravine
to the west.
