this would be a good line to simulate because there are both hourly greater anglia services and freight services. The lines run from Ipswich- Lowestoft and Felixstowe, plus freight terminals along the Felixstowe section and a small spur of track from Saxmundham to size well nuclear power station. Class 755/3, 755/4, 66, 70 and formerly class 156, 153 and 170’s operated passenger services. As well as that, the line should be simulated because of its quirky ness - there are multiple passing loops and landmarks. https://en.m.wikipedia.org/wiki/East_Suffolk_line https://en.m.wikipedia.org/wiki/Felixstowe_branch_line https://en.m.wikipedia.org/wiki/Aldeburgh_branch_line
So around a year ago, I think, I proposed a wherry lines add on. I think this is a good suggestion as I live near Lowestoft and it would overall be an excellent route for tsw2. Thanks
