I was out filming our light rail and I must admit I was kind of close to the tracks. I was trying to look at the train coming from the north (track further from me) when a train coming from the south came by and spooked me. The train operator blew his horn at me and I'm pretty sure he called into the transit police too to report a "suspicious character". After I took the video I kept on moving and noticed them across the street. I knew they were coming for me. Asked me why I was shaking so much (my jacket was open and we were getting a cold front today), why was I filming the train, etc.
They told me I was too close to the tracks and I apologized and asked if I was free to go. They weren't even around when I filmed the train so somebody called in on me!
