If their was a update for free to add a route from London Victoria to Brighton and even add water loo to Portsmouth and maybe have routes added
Free is out of the question. All of the research must be done and to get the licences for GTR and to for all the time and effort. If it were to be done, they would charge maybe £24.99 or £29.99. I would be happy with either.
It would be amazing to have free routes. I doubt the employees at Dovetail would stick around to make them when their bosses tell them they aren’t getting paid. Unless the magic content creation pixies (friends of the tooth fairy) make the routes you are just going to have to pay for them. London to Brighton is a very popular suggestion.
I wish we could get free routes but DLC's cost money so the employees can earn their pay also to pay the expensives of licensing & other things
