Hi, The Captain.
Actually, I've been a developer of Train Simulator add-on routes, timetables and scenery for many years. I have a "working" name, but I won't revela it. If you've ever bought an MSTS add-on, you've probably put some money in my pocket.
And I also do a bit of layout work on Trainz, although not much as I prefer MSTS (only because I've been doing it for longer).
And no, I don't want to work on any projects. I am always a lone worker! But thanks in advance.
