So tsw 2020 base edition has rapid transit great Western railway and long island railroad. If you go on the xbox store and click on tsw 2020 and click on view editions it will show you the other bundles for the game
Rapid transit is wrong. The standard version of TSW2020 has Northern Trans Pennine, Main Spessart Bahn, Long Island Railroad and Great Western Express
I recently saw the exceptional TSW2020 collector's edition at base.com for £14. For that you get 6 routes which will migrate into TSW2 (you need to send a photo of the disc to customer support and they will email you the activation codes). The advantage being that you have a physical copy to hold and to keep (my preferred choice)...or, should you feel the need, the option to sell on once you've obtained the activation codes. So, depending on your moral stance you get either 6 routes (GWE, NTP, LIRR and some German stuff - I forget which) for £2.50 each or 6 routes for maybe £1.00 each
