i think the Mersey rail network would be good. so Chester to Southport and other places that they go to. the Wirral line+ northern line . The reason i request this route is because it is a beautiful railway, and i think plenty of people will purchase it. The unit's that are operated on this line is the class 507+508 with the new class 777 coming this year.
