Just a quick look at Edendale, 1974 and today. The turntable at the north end was installed sometime between 1947 and 1955. I don’t have any documentation of there being a turntable in any other location at Edendale but the original locomotive depot at Glenham closed with the Wyndham-Glenham section of the branch line in 1930. The remaining section of the branch closed in 1962.
