Just noticed something though... that's a very old version of that route. You may want to download the latest one. Blackpool North actually looks like Blackpool North on V2.0.
No... That's Northern Lines Electric. Dutchess's screen shot has the old North Station and canopy models though, so it's an earlier version of "Northern Lines". Latest version is here.... https://www.ontracksimulation.com/northernlines.html
It's an old screenshot taken before v2 was released (might actually be the very first release). I already have v2 installed.
I had to go looking to see where my screenshot of a few years ago was made and there are a number of stations next to a bridge But not many that go to Single Line
So between Stranraer and Castle Douglas (the part of the route I'm least familiar with). Won't get a chance to go on PC until this evening so I imagine somebody else will have got it by then.
