Well, the original post was posted in 2008. Lack of updates suggests maybe it's not getting anywhere fast :-(
I'm a complete newbie in model train land, but I do have engineering degrees. I'm totally not up on kitbashing yet :-( but with a bit of help I might yet get there (I hope).
I also need to remodel my garden to deal with where tunnels and cuttings need to go, and where bridges need to be put to deal with the obvious floods that don't drain away quickly enough. (Reinforcing of tunnels will be done with GPRF tubes, I hope, if the company didn't go bust yesterday).
