Hi here would like to see the Wherry Lines as I know the WCML be big as but small size project I know this route wont take that long to make if you don't know about the Wherry Lines it runs from Norwich to Great Yarmouth and Lowestoft it got 14 Stations it around 25 miles
Not sure how you arrived at 25 miles here, I think it's closer to 42 miles if you count all branches. It sounds like a nice route network, have fun with it and keep us posted
Also be careful not to underestimate the amount of time and work it would take to produce a high quality route. Even the “smaller” routes take a lot of time if you want them to be as accurate and detailed as possible
Making something in the Editor is hard work. It's very unlikely that anyone will make something based on a suggestion from a stranger online, rather than because of some reason that's important to them personally.
