The STANDARD license generally allows you to save the game state, so you can continue to play at a later time. The EDITOR license allows you to create and save your own territories as well as any PREMIUM version of any territory. Both standard and editor licences are valid for the installation of CTC for which the licenses were purchased for.
The PREMIUM licences, which are valid only for the territory it is assigned to, may give access to features not available otherwise. Examples may include the permissive stop feature (after stopping the train may proceed on red without having to get permission from you first), switching routes, or future features like helper function or the requirement of crew changes if the crew time expires. As already mentioned, this licence allows you to modify the territory if you also have the editor license.

As for more territories - it has been a little bit quiet in the last couple of years, but we have received just recently a bunch of territories that we are working on right now for the purposes on publishing on our website. There are at least a dozen of them in the loop.
