not being ungrateful especially if it turns out to be free, but old trains, yes people appreciate them for sentimental purposes, but me personally i want whats current and i love it because i love realism and authenticity. So why not Waterloo mainlines, or Liverpool Street lines? Euston or Kings Cross?
Nothing is going to be free. It will likely be $25. And WSR allows you run the real life full route. If DTG did a Mainline out of London it would not even be close to the full route. The longest Mainline I see DTG doing is like King’s Cross to Peterborough if that. Not to mention WSR provides future opportunities for a steam loco dlc.
