Was wondering if there are any merges for these two routes and if so, 1. Which is the best and 2. Where it can be obtained from? I would prefer not to have to pay a subscription, i.e. ATS etc. Thanks in advance.
I'm sure there's one which includes Edinburgh-Glasgow. No knowledge other than that but have you asked Google?
I’ve done a bit of Googling and saw something about the Edinburgh merge but not one that lets you run from Preston to Glasgow.
WEST COAST MAINLINE – NORTH WEST AND SCOTLAND – V1.2 (03 AUG 2018) https://xcroute.com/extended/?page_id=5833 This route is a direct merge of WCML North, WCML Over Shap and the DPS Edinburgh to Glasgow scenery extension to Carstairs > https://www.dpsimulation.org.uk/edinburghglasgow.html I googled WCML Merge and this was the first result
