One of the few sites with authoritative information ceased to function because the host Google no longer supports the format. https://sites.google.com/a/railsimdev.com/ Apparently the site didn't get automatically migrated to the new platform? https://support.google.com/a/answer/9958187 Is somebody (at DTG?) in charge of this information? Have I overlooked something, or not searched correctly? Indeed, I didn't search correctly on this board. The new site has been found here http://tscdevdocs.co.uk/ I updated my bookmark, you got yours updated?
Yeah, TrainSim-Steve had announced it somewhere... https://forums.dovetailgames.com/threads/developer-documentation-unavailable.70268/#post-654851
