Sort of - they are both the Stand Alone versions of that section of route. No. Just trains has two different versions of the Cornish Mainline The version released on Steam and on Just Trains Website is a Stand Alone version. https://www.justtrains.net/product/cornish-main-line £21.99 The version that is part of the full route is cheaper as it uses some of the assets in the other section https://www.justtrains.net/product/western-mainlines-cornish-main-line-extension - £18.99 The Plymouth area is a good example as the Assets, (Buildings, Track, Signals etc), need to be in the Stand Alone but are already in the South Devon Mainline section so don't need to be included twice If you want the entire route buy it a section at a time as funds allow WML is currently £19.99 The South Devon Mainlines is £12.99 And the Cornish Mainline is £18.99 Peter
Let's use a real-life example, shall we? Way back a few years ago, a PAX event was occurring where they were having a Pokémon-themed party. Companies didn't do anything to stop the event, presumably because it brought attention to the brand and helped sales. However, as soon as they, in this particular year, started charging $2 for tickets to cover the cost of door prizes, The Pokémon Company International - who had been observing quietly these parties for years - pounced on it and sued for use of their images (namely, Chespin and Pikachu on a poster) to make a profit. It didn't matter that the tickets covered the cost of the prizes that he bought with his own money; he was still saddled with a huge legal cost for selling those tickets. Otherwise, nothing might have happened. So I am not directly siding with either opinion above; I am merely offering context to this discussion.
