Caption: CN Z4a boxcab electric locomotives 6723 and 6722 pose at Val Royal station, working Montreal area commuter duties on the Deux-Montagnes line. Built in the mid-20's by English Electric for the National Harbour Board, the units worked with similar looking GE boxcar electrics and would be renumbered once or two over the decade, until the end of their operation in 1995 (the old electric fleet was replaced during a modernization program of the line). Val Royal station, originally named Lazard, was renamed again and is currently AMT's Bois Franc station.
