Description:
Bell Rose No. 1006, a 1907 American Car Co. Brill "Yellow Jacket," leaves the Water Street Yards. This trolley is approximately where the Darigold Dairy is today. In the background you can see the Grand Avenue viaduct. Several lines continued south all the way to Oregon City (and Oaks Park, of course). I think that staircase on viaduct is the one up near Caruthers street.
This photo is from the 1940s, at the earliest. By this time the smaller city trolley lines had been almost entirely discontinued, and although interurban service to Oregon City continued to do decent business, the interurban line to Gresham was shorted to to the Bell Rose stop.
