Do the "latest-greatest" Trainz versions require the Steam program to work?  I see that Trainz apparently uses Steam to download Trainz 2019, but when some of the later versions were being developed it was said that you would have to have a Steam connection to operate these later versions.  If so, for those of you who have the latest versions how is that working for you?  TS-12 is my latest version to date .  I ask because my grandsons play Steam games on my PC.  Steam is constantly verifying files and/or downloading and installing updates, usually to each bootup.  These can take a long time and slow the PC very much for any other use.  Right now I am looking at one such download/update that has been running for over and hour and a half and still has not finished.  And, I don't even know what it is installing.  I think it must be related to the Steam infrastructure rather than a game, but I don't know because all it says is "Updating Steam, Insatalling Update".  Does anyone else have this problem?
