There aren't many freight only lines in the UK but the Dudding Hill Line is one. The line isn't particularly long but it meets with 4 mainlines (GWML, WCML, CLML, MML). It also shares the NNL, and passes the Piccadilly, District, Central, Jubilee and Metropolitan lines. As is with freight lines, this line isn't too busy but promises loads of Ai traffic, so has a one-up over in-game American freight routes. Why this line is unique: The actual freight only section is unique for still using semaphore signaling and still having signal boxes still present and active at Acton Canal Wharf, Neasden Jn and Dudding Hill Jn. The freight only section also has a speed limit of just 30mph. Locations: With no spurs anywhere, this line is just 8.5 miles long so to make up for linearity, these spurs should be included: from Acton Wells Junction to Acton Yard, Wembley yard, Willesden Freightliner Terminal, from Neasden Junction to the nearby sidings adjacent to the Chiltern Mainline, and the both lines from Dudding Hill Junction to Cricklewood and Brent Cross West. With those spurs included, these are all the locations (including passenger stations) (from South to North): Kew Bridge station Kew East Junction South Acton Junction South Acton station Acton Central station Acton Main line station Acton East Junction Acton Wells Junction South West Sidings West London Junction Willesedn Jn High Level Junction Willesden Jn station Willesden Freightliner Terminal Harlesdon Junction Willesden Brent Sidings Brent New Junction Wembley Receptions 1-7 Neasden Junction Neasden Down Sidings Dudding Hill Junction Cricklewood Curve Junction Cricklewood station Cricklewood South Sidings Cricklewood Depot Junction Brent Cross West station Motive Power: Being a freight only line, I think it's sensible to include two locomtives, namley the Class 66 and Class 60 in Colas Rail colours (assuming a license can be made). The class 66 would require alterations to the model, most notably different headlight clusters and a removed buckeye coupler, considering how many time the 66 has been included in an add-on, it's genuninley ridiculous that we only have 1 model, I'm not counting Engineering Express considering there are multiple inaccuracies with 66587 and the DRS model. The class 60 is a much requested locomotive that was infuriatingly emitted from Cargo Line Vol.1, which was so annoying because these were the dedicated locomotives on Oil trains in set time period on the MML and GWE, the routes that the pack was primarily made for. Timetable Layers: Driveable: Class 378 between South Acton and Willesden Jn Class 700/0 between Cricklewood and Brent Cross West Class 70 on suitable freight services from the Class 66 or 60. Ai only: Windsor Line traffic (SWT Class 350/450 mock-up) GWML traffic (Class 43 HST, Class 166, Class 165, Class 360/2 mock-up) WCML traffic (Class 390, unbranded LM Class 350, Class 377/2 in 8car consists (because it's 2017)) Watford DC line traffic (Class 378, 1972 tube stock/Class 499/2) MML traffic (Class 43 HST, Class 700/0) LU traffic (1972 tube stock, LU Class 484)
