Long Routes

[Doblodiesel]

I have not been on this site for quite a while and have got out of touch with things but I am looking for a long circuit route with double tracks for TRS2006.
I seem to remember a route called "The big one" can anyone give recommendations please?

Are you looking for a UK route? If so, I think Rosworth Vale fits the ticket (sure it was in TRS06). There is an I-portal at one end, and a lengthy loop at the other. If you wanted to get rid of the I-portals, I'm sure you could put in a tunnel loop.

Cheers.
