This route would start at London kings cross and go to Peterborough completing a 72 miles route along with the 3 mile route to moorgate adding up to 75 miles of track, there is a possibility of going to Cambridge or including the loop line around Gordon Hill and Enfield chase. This route would be set in 2018-2025 for simplicity sake. Layers/already made DLC Great northern Class 313 PEPs The class 313 would run moorgate to welwyn garden city/Stevenage services along with some services heading out of kings cross This train would be in first capital connect livery with Great northern branding. This would be nothing but a relivery and adding some functions along with a pantograph. Class 387 electrostars These trains would also go up to Stevenage from kings cross and turn off as AI going to Cambridge/kings lynn/ely I believe some of these go Peterborough but I am be wrong. Mainly fast or semi fast services This again would be nothing but a reskin LNER Class 43 HST These would run intercity services to and form kings cross to Peterborough stopping at Stevenage time to time The class 43 would be a reskin of the one we already have. Thameslink Desiro citys Class 700 Thameslink run class 700 between King's Cross and St Pancras International(Coming from Horsham/three Bridges/Brighton) to Peterborough and Cambridge they mainly run semi fast services up and down the line Class 801 azumas/at300s Again the LNER class 801 would run intercity services between King's X and Peterborough Potential addons Great northern class 365 networkers The class 365 would run London to Peterborough/Cambridge commuter services alongside the 387 or 700 (321s for earlier periods) depending on year set. These would be in the all white livery or the purple slash on the top which they had near the end of there time. Potential to layer onto a back-dated southeastern or a scotrail route(a few were with scotrail for a brief period) LNER Class 800 azumas/at300 Would take the base model of the 801 and require a few adjustments. Would layer onto other routes Class 91/225s Between these and the 365s they are definitely fan favourites they would run services along side the HSTs or Azumas Class 717s Replacing class 313 services Less likely but worthy mentions Class 379s electrostars Recently acquired by Great northern to run alongside the 387s Hull trains We would see the class 180 if the route was set anytime before late 2019 And the 802 if the route was set from late 2019 But I believe the 2 ran along together at some point. The 802 could be implemented but would only be playable between King's X and Stevenage. The 802 could also layer onto the other ecml route but this train would most likely come as a layer from a route made for this train. Grand central Class 180s These would run to and from kings cross stopping at Peterborough around 4 times per day meaning these might come as a layer rather then dlc - could be used on a EMR MML route or a FGW/GWR route aswell. EMT 158s could layer at Peterborough Extra bits Over the years we've seen many different operators and trains LNER VTEC GNER , East coast, National express east coast, Thameslink, Great northern, FCC, Lumo, GC, HT Loads of liverys , trains , eras , I could see at least 20 different timetables in order to fit these in as the operators and rolling stock was always changing.
