I don't believe Sodor Island will appear in TSW because it's a fictional island, so it doesn't exist. It's from Thomas the Tank Engine. If you really want something like this, please give more description and details, along with some pictures, of what it should look like and how it should be put together. What exactly do you want?
Excuse me, he doesn't have enough information, and he's coming up with something that doesn't even exist in the real world. If he really wants his thing released so badly, even though it's not entirely clear, then he really should write and post more in this post. Below is a link for you if you want to know more about his little island and what it is. https://en.wikipedia.org/wiki/Island_of_Sodor
If that were the right question, isn't it possible that multiple players would enjoy this? And the next question is, do you think the game developers would actually make this?
Well a lot of forum users said a Sodor route would have been preferable to inserting Thomas on the WSR.
Yes there are Thomas locos in the game So it can possible be combined with the route. Excuse me for that, I forgot.
OP certainly needs to elaborate including how or where DTG could look to find terrain that might emulate Sodor, given the editor keys off real world DEM and LiDAR data. (One of the Scottish islands, perhaps). Or maybe some sort of expanded model... However despite the fireside chats and pink headphone presentations, Thomas and its reskin seems to have shared the fate of all the rest of the DLC - five minutes of fame then quietly dropped, never to be touched again.
Yeah what I meant is TSW doesn't need any fictional route, or content whatsoever. I formulated it in a sarcastic way, but it's just my opinion and everyone is free to think the opposite.
