So I took a trip on the new metro rail service up in SLC today (Front Runner.) It seems to me a much needed, and very viable service---especially since we were moving faster than the freeway.
Anyhow, I sat in the head-end car on the trip back, and could hear the horn over the music on my iPod (okay, it was classical,) and I noticed that they were not blowing the horn except for when anyone was in the right-of-way, i.e.; no bells on movement, no horn, nothing. This seems rather odd to me. Is this because they are a regional line?
