The part of the S&DJR from Blandford Station would remain open for milk traffic accessed by a branch from Broadstone until 1969.

Peter Kerslake says "Bailey Gate was situated at the southernmost section of the former Somerset and Dorset line and was the centre for milk traffic with the large milk processing plant which generated a great deal of railborne milk trafffic visible in this view.
During particularly busy periods of passenger workings, especially on Saturdays when the line was handling many long distance passenger workings, the loaded milk tank wagons would have been added from here at Bailey Gate to the rear of northbound passenger workings such as the late afternoon passenger service from Bournemouth West to Bristol rather than to be run as a separate milk train."
