Hey everyone I have a pretty good suggestion since I love the London underground / Overground network so much I would like to suggest adding the Circle and District line as I would love to drive the S Stock as well as the amazing historic D78 Stock trains too I think this would be an amazing addition to Train Sim World 2 I would also be more than happy to pay for a DLC such as this expanding upon the London Underground Network in the Future. S Stock London Underground Train: The London Underground S7 and S8 Stock, commonly referred to as S Stock, is a type of passenger train running on the London Underground's subsurface lines since 2010. Manufactured by Bombardier Transportation's Derby Litchurch Lane Works, the S Stock was ordered to replace the A60, A62, C69, C77 and D78 stock on the Metropolitan, District, Hammersmith & City, and Circle lines, which all dated from the 1960s and 1970s. The order was for a total of 192 trains (1,403 cars), and consisted of two types, S7 Stock for the Circle, District and Hammersmith & City lines, and S8 Stock for the Metropolitan line, with differences in the arrangement of seating and number of cars. Both types have air-conditioning and low floors to ease accessibility for disabled people, and also have open gangways to allow passengers to move from one car to another whilst the train is moving. D78 Stock London Underground Train: The London Underground D78 Stock, commonly referred to as D Stock, was a type of sub-surface rolling stock which operated on the District line of the London Underground, except on the Wimbledon to Edgware Road service. The first units were withdrawn in January 2015 with the last withdrawn on 21 April 2017. A60 Stock London Underground train: The A stock is a full-size subsurface-stock train which was built in the early 1960s by Cravens of Sheffield in two batches, designated as A60 and A62. It is used on the Metropolitan Line, from Aldgate and Baker Street to Amersham, Chesham, Watford and Uxbridge; it used also to operate on the East London Line, until LUL service was withdrawn in 2007. The A subsurface stock is the oldest type of train in passenger service on London Underground, and the only one old enough that it has separate controls in the cab for motoring and for braking. Feel Free to have a read on the brief history and background of the trains and it would mean the world to me if this amazing community considers my suggestion and I would like to say a massive thank you to everyone for having a look if your just visiting or voting for my idea and stay safe everyone.
