A derailed trailer on a CN train caused some traffic woes for drivers in the Trafalgar Rd. and 17 Sideroad area Thursday afternoon as the 73trailer RoadRailer train blocked the tracks at those crossings while CN staff attempted to right the empty trailer. Pictured above is the Trafalgar Rd. crossing north of Maple Ave. The trailer, the last one on the train traveling westbound from Toronto to Detroit, came off the tracks at 4:45 p.m. and dug into the ground east of Trafalgar Rd. At press time a CN spokesperson said the cause of the derailment was under investigation. No one was injured in the incident.
