A suggestion
There are several operational terminal stations on the DLS. But if you are not so much concerned about the buildings, I say scratch build it yourself using AJS invisible stations (there are up to either 6 and 8 track versions either built in or on the DLS).
As long as you extend track beyond the midpoint so trainz can fit and unload/load properly, and also install track-end bumper track objects, combined with platforms, platform roofs, including barrel-vault roofs on the DLS, you can get exactly what you want. You will have much more flexibility than using someone else's vision, which may not be bad but doesn't meet your needs.
