Indeed, Brandypatch and you are the only UK shots I could see.
I'm not counting them and have actually been helping with some of their beta testing in recent months, but the like of tmz06003, warbo, nexusdj, masontaylor, fudginator, greeni, and several others, all of whom were prolific in their UK output. I realise real life can often put the scud on things such as Trainz, it's just a shame to see them go.
I've noticed that the TS fanboys don't usually approve too much of the 'fantasy' routes that have been released and I certainly haven't bought any. I thought multiplayer surveyor would make it a lot easier to collaborate but it doesn't really as it is a bit limiting.
