I don't know what the problem is, but many have, and I have it too. In the Quick Drive menu I actually have 90 routes, divided into 8 to 9 pages. But now only 3 pages are displayed, but if you go to the Editor, you see the list of routes and all routes are still in the game. And I tried to search the routes with a diesel train, but only 3 Pages are still shown.
Verify your game files mate. TS could do with a truly sensible system for people with lots of DLC. Odd that it's never been sorted out.
This worked for me when I lost QD routes. Go to your Contents folder in Railworks. Delete SDBC Cache Bin Delete SDBC Cache Bin MD5 Fire up TS and you've got your QD routes back. IIRC a File Verify didn't work.
Do you have the right loco set? If you select an electric loco for instance, the non-electrified routes will not be present in the quick drive menu.
OP said they used a diesel but still QD routes were missing. I've lost QD routes a couple of times, a search on the Steam forum gave me the solution I posted above. It works.
No worries. It does seem a common occurrence, the solution should be pinned somewhere accessible. (Along with a link to the Manuals).
I wonder if DTG could place all the Manuals on a page that anyone could access? That way you could have a read before a purchase Peter
Also remember that not all routes have quick drives, so unless you have seen more quick drives before there is probably no issue
Helps if you read the first post that says "In the Quick Drive menu I actually have 90 routes, divided into 8 to 9 pages. But now only 3 pages are displayed" So if he had 8 to 9 pages of Quick Drive and now only 3 there might be a problem
