I've no idea if this has been done before but it might be interesting if people shared their 'fantasy' preserved railway - which British line you'd choose to reinstate if you had the power, money or support. It could be one which is disused or was lifted decades ago, or perhaps one which now operated by National Rail. Would you be fairly faithful and use locomotives from the company who used to run the railway in question, or would you be a bit more eclectic? What would set it apart from the many other preserved lines out there etc? I'll answer all that when I've had a bit of time to think about it but I'm quite intrigued to see what other people would do!
