The North Downs line is an interesting route that runs through beautiful Surrey Hills scenery for about 30 miles. The line runs from Reading on the GWML through Guildford on the PDL and Dorking on the Mole Valley Lines to Redhill on the Brighton Main Line. A lot of trains reverse here and carry on to Gatwick Airport. In the modern day, trains consist of 165/166 turbos (I will get to this later). The interesting thing about it is that it is a non-electrified branch route deep in third rail territory, and a GWR route in the middle of Southern and South Western territory. In the future, Tri-Mode Class 769s (converted from 319s) will operate the route. There is a daily cross country service operated by voyagers that runs as far as Guildford. Sections of the route are third rail electrified and shared with SWR, these include Reading to Wokingham and Ash and Wanborough to Guildford. The Reading section in recent years has been operated by 455s, 450s and 458s, and the Guildford section by 450s and 456s. In the past, even more interestingly, the line was originally operated by the South Eastern Railway. During the steam era, operation was transferred to the GWR and in the later years it was operated by first-gen DMUs and Moguls. The Route in TS I think the route would be a nice one for TS. It is relatively short, which fits what DTG have been doing recently quite well, and I think the main advantage it could bring is an updated 165/166 to TS. The only networker turbo we have in game now is nigh on 15 years old from the original railworks, so I think it is high time for a new one. I think it would be great if the branch line from Ash and Wanborough to Farnham could be included, which would greatly increase the run-ability of the route, to simulate the SWR Guildford - Farnham services. In terms of stock, I think a networker turbo, a 450 desire for the SWR sections, and maybe even the return of the XC voyager, albeit unbranded, for the once-a-day service. Perhaps an AI only 377 for the Redhill - Gatwick Airport section as well.
