Caption: Ontario Rail Association's ex-Canadian Pacific steam engines 136 (A2m-class 4-4-0) and 1057 (D10h-class 4-6-0) head westbound on the Galt Sub crossing the high Humber River bridge by Lambton Mills, originally built by the Credit Valley Railway in 1874 (since upgraded by CP, but some of the original CVR stonework can still be seen). They're travelling west on a fantrip excursion to Streetsville, and up the Orangeville and Owen Sound Subs.

"Credit Valley Railway" 1057 had been recently overhauled for operation at CP's John St. roundhouse in 1971, but had undergone additional work in 1973 (emerging fully overhauled on May 19th). "CPR 136" had been working out west on its movie stint for CBC's "The National Dream" in May-June 1973, renumbered as "CPR 148" and was now back with the ORA (now 136 again, but still somewhat backdated with the old-style large tender numbers and other details. Apparently the CBC still needed to shoot the winter steam scenes with 136 for the production later in December, in the Havelock area). This was their first of many excursions together after 136's return and 1057's overhauls.

At the time, ORA had had acquired the two steamers, some heavyweight passenger cars (mostly ex-TH&B), and were expecting to acquire a piece of CN's Beeton Sub from Georgetown to Cheltenham for a start-up tourist line (but that apparently fell through). In the interim, they ran many fantrips in the Southern Ontario area. Some years later, the portion of the Beeton Sub from Tottenham to Beeton would be acquired in the 80's, giving a start to the present-day South Simcoe Railway operation.
