I know I'm at the risk of a lot of abuse here but there isn't a Rail Enthusiasts/Trainspotters forum anywhere. OK, my problem is that I've been asked by a friend to build a stand-alone Windows program for Rail Enthusiasts. It's proposed that it be similar in function to PC Tops but with refinements. I am not a Rail Enthusiast/Trainspotter so I've no inside knowledge and must therefore rely on help and input from those who are. My questions are: Is this a viable proposition? Would it sell? If this is your hobby what would you like to be incorporated? If you want to PM me fine, but I'm really in need of some encouragement before I spend a year of my time, and probably around £200, programming a product that is only of interest to one man.
