Here is an aerial view of downtown Nanaimo ca. 1940. There is a myriad of details to see.
A few that catch my attention:
The coal wharfs are in operation.
The bastion is visible. (B)
A CPR steam ship is at the terminal. (O)
Two steam powered passenger trains are at the station. (S) If you zoom in you can steam escaping from the southbound locomotive.
The is an engine house (for locomotives) at X. It has a transfer table rather than a turntable.
The photo for my avatar was taken somewhere near the T.
There is a structure at the intersection at A. I have a vague recollection that it was access to underground public washrooms. Perhaps someone can confirm that.
The Pygmy Pavilion is the building with the striped roof. Stewart and Hudson building supplies is the large building on Terminal Avenue right above the pavilion.
