I still remember getting really excited about this Kuju route released with Rail Simulator...and my unending disappointment about how it looked. The reason for my excitement was (and now is again) because I live only 4 miles outside Bath and about a mile from Midford Station, just off the old Camerton line that passed under Midford Viaduct and was used for the filming of The Titfield Thunderbolt*.
Sad to say I arrived here far too late to see either line working...but this does not look like it will disappoint

On an aside, all of Golden Age's routes and assets are worth a good look - top quality.
