@learmoia -I wish the Double Track concrete tie curves were available in black ties to match the traditional track. (it has broader curves than single track..)
A paint pen is your friend here . Mike
I was planning that but the overall geometry of the superelevated curve was limited by 45 degree curves, so you can only do 45 (using just the 22.5 easements) then 90 - 135 - 180 deg increments and it didn't work where I wanted to use it.
Selling the Super elevated track in two or four piece packs of 22.5 degree segments would have been easier to work with.

or my 90 degree curves I ended up using using
718-15>481-15>381-30>481-15>718-15 for the outer curve
718-15>481-15>348-30>481-15>718-15 for the inner curve
For the big S-Curve east (right) of Lockport yard, I used 718-481-718 combination.
I ended up using the double track concrete curves on the 90 degree curves in the utility room.
