Caption: Interesting combination rolling along the Grimsby sub past the Merritton station, which is out of sight behind this train. It appears CN 4599 and 4594 have been out working industry along the line and have combined their trains and ready to head back to Niagara after perhaps dropping one 'set' off at the Merritton Yard. I have forgotten how operations proceeded along the line here but remember it being very active with local industry.
