Caption: The first pair of TTC's brand-new Hawker Siddeley H1 subway cars (5336-5337, delivered to Davisville Yard earlier that month) operate on a special official train, heading southbound in the open-cut portion of the Yonge subway line at Jackes Avenue (taken looking north from Woodlawn Avenue).

According to notes by John Bromley and Robert McMann in an old UCRS issue, this was a test train preview run of the new H1 cars with 40 transit officials aboard, run on the morning of May 30th 1965 (departing 8:30am, with the only two cars delivered to Davisville) between Davisville Station and Union Station, followed up by breakfast at CP's Royal York Hotel. The pair of new cars had previously been testing on the line, and it was expected full consists of the new H1's would be in revenue service by mid-July 1965.

This section of the Yonge subway line between St. Clair and Summerhill stations would be completely covered over in the following years, as part of development of air rights over the subway line. That high bridge for Jackies Avenue would be completely level with the new ground over the line, with nary a hint of the subway cut below except some bridge railings that were left in place. Today, a very large apartment building resides over the space in the foreground, with greenspace over other portions.
