Hello I started playing with Caltrain yesterday. Here are two thing I noticed: 1) The alerter is not working in the cab car? (Sounds familiar, alas). 2) I drove an all stops southbound service. After leaving Laurence station the line goes from 4 tracks to 2 tracks. I was stopped by a red signal outside Laurence; it is the signal that protects the "4 tracks to 2 tracks junction" (I'm not sure there is a technical name / railroad lingo to properly define it). I was on the siding track and I thought maybe a bullet was going to pass me on the main on my left but that was not the case. Then I saw a northbound train coming towards me on the main; as soon as it passed, I got a clear signal. I thought the northbound track was out of order for some kind of maintenance but after a mile or so I met a northbound train on the northbound track. How comes?
