Self-propelled aluminum cars approach (leave?) Ottawa's Union Station through the rail yards on the east side of the Rideau Canal in the mid-1950s. They're the cars behind the CP passenger train in the foreground. The other side of the canal doesn't look much different today! (CSTM Stowell Collection)
While we are on the subject of trains ... here we are looking down from the Mackenzie King Bridge at the end of the train sheds at Union Station. It was under these sheds that you boarded your train from Ottawa to Parts Beyond. Date is about 1959, judging by the cars in the parking lot.
2822 with Pool train (note CNR car second from rear) at Deep Cut east end of Ottawa Union Station due to depart A. Daily except Sunday non-stop to Montreal. Stopping at Montreal West, Westmount and due to arrive Windsor Station at A.
