Jon,I know Tim stated the route was based around the jubilee year (1977), however it always appeared to me more based around 1986/7, but without the previously mentioned electrification of course.
I think its the trackwork thats based on the late 80's in the original. The stock is based on the jubilee year. To some extent we have the same problem in PLUS as its very difficult to get hold of actual old track plans. Some parts though are based on real older trackwork, where I do have info, and some is just guesswork where the Beeching Cuts have been reinstated.
Three examples of real pre 70's/80's track:
Skegness,
Stow (near Lincoln),
Hunstanton.
