Hey, if we already own the NWC will we get the extension for free or will we have to buy it again? thanks
If you read the information about the Holyhead Extension you Need To Own NWC for it to work. And you will probably find it will install another route in your folder so you will have Crewe - Llandudno & Crewe - Holyhead Peter
They'll probably put it out as an expansion pack for which you need the original to run. Hopefully they won't do another South Wales coastal and end up with two different routes
DTG WILL release it as two Separate routes Even though it would make sense to bring it out as a proper extension. Mannheim - Karlsruhe is now Frankfurt - Mannheim - Karlsruhe Chatham Main Line is now Chatham and Medway Valley Line And South Wales Coastal as you said
