My copy of MSTS always took ages to find (at least 45 minutes) when I wanted to reinstall it. But fortunately, it's sitting in my pile of games now.
I am slowly gathering information on a route I was interested in doing years ago, and I am around halfway laying the track. It includes a 56 kilometre long straight, and some sections of the line include stations that are more than 20 kilometres apart from others. It also features some interesting hairpin curves around some hills. At the moment, I'm waiting for the National Archives to find the second half of the gradient chart to the selected end point. There is no guarantee or promise of it being released. It's mainly something I'm working on just for the hell of it.
However, version 1 of the Northern Narrow Gauge is close to release now, due to the VM metre gauge being approved to be hosted on Steam4me.
