I would like to suggest this commuter line for TS2018. It's a fairly self contained line, formed from the remnants of the Manchester section of the Woodhead Line. It's run by Northern using Class 323s, although Class 319s are likely to appear in the future. It serves 13 stations, the final two - Glossop and Hadfield - are on seperate branch lines, meaning that trains switch directions in order to serve both stations. The 13 stations on the line are as follows: Manchester Piccadilly Ashburys Gorton Guide Bridge Flowery Field Newton for Hyde Godley Hattersley Broadbottom Dinting Glossop Hadfield. A visualisation of the Line can be seen below courtesy of Wikipedia: The Class 323s have served the line since 1997, originally in GMPTE livery, followed by First North Western, and then finally Northern Rail.
