A new scenario is available from my website: "ATSF 'San Diegan', Train 72".
This scenario puts you in charge of the ATSF's express passenger service from Los Angeles to San Diego, the 'San Diegan'. Train 72 leaves LAUPT in the morning. The scenario has been split in two parts, each about 90 minutes long. You'll see a lot of AI action, especially in and around L.A.
