Caption: GO GP40TC #505 pushes a consist of single level cars up the CN Bala Subdivision through would appears to be Pottery Rd. Scanned from a slide in my collection; the only information on the slide is "August 1978" but judging by the date and surroundings it is most certainly somewhere in the Don Valley on the Richmond Hill line. Another interesting thing to note is the GO green headlight housing on the 505's nose; definitely an anomaly that likely didn't last too long.
