Westbound Metra track inspectors truck. The River Grove Metra commuter rail station. December 2006.

I took this photo looking east, at the Metra station in northwest suburban River Grove Illinois USA. The maintenance department superintendent spotted Me with My camera, gave Me a beep on his horn, and waved nicely to Me as He passed through the station between train times. This is a behind the scenes view of maintenance operations on a commuter rail system. He may have been enroute to a job site.
