Looking at the SB Despatcher Board, it looked as though it was possible to route a train from Riverside Junction towards East LA and have it pop out at City Of Industry. However when I tried sending one of my AI trains that way, it just seemed to get swallowed up at Streeter. So I presume that short section of line isn't actually included and if you want to get to COI or access to the East LA line you can only do it from Soto Jn?
