I had thought that I lost this footage, but I found it in a pile of old video files. Here for your viewing pleasure is an M7 RFW ride into GCT. I was lucky enough to run into a super cool engineer who allowed me to stand up front while closing his cab door for me to do so. All stations, signals, and interlockings identified. I wasn’t sure of the names of some of those interlockings in the tunnel, but I put the correct names in graphics.
