UPDATE (1:45 PM): Yates County Sheriff's Office has released more information about this morning's train derailment.

Upon arrival of multiple fire and rescue crews, it was found that a train engine belonging to Finger Lakes Railway, had struck a train derailment apparatus that was placed on purpose on the rail line, as crews were working on a grade crossing on the line. The derailer device had been placed on the track to protect crews working in the area. 

Finger Lakes Railway President Mike Smith tells WENY News the derailment device was placed on the wrong rail inadvertently, and an internal review of practices will be conducted. 

The derailment caused the train engine (with no cars) to overturn onto its side on the east side of the tracks. The operator of the train was identified as Thomas R. Lewis and was brought to a hospital for a possible arm injury. 

The New York State DEC was brought in for a small fuel spill, due to the overturned train. Fuel was pumped out of the engine and mitigation efforts are underway for fuel that spilled onto the soil.
