OK -- I bought TS 12 (download). Downloaded all 6 files and went thru setup. The initial setup automatically applied patches to bring the build up to 49922. Program ran fine, but after I exited the program I was unable to get it to run again. I deleted the install and ran the install again...
Always glad to see BH - it is fun and NOT so easy as they say -- besides the "score" at the end has no relation to how well one drives.
In any case, in Trainz 2009 one cannot complete the scenario as a yellow signal after the first stop is coded as a red and so the game is aborted - or is it...
