A 25-year-old homeless man is recovering in the hospital after being hit by a SMART train in Petaluma. Investigators say he was walking with his bicycle when he was struck. But they’re trying to figure out why he was so far away from the railroad crossing. Officials say the train was going about 35 miles per hour at the time of the collision, adding that the train blew its horn but couldn’t hit the brakes in time. It’s the first time a SMART train has hit a person since November.
