Looking towards Bournemouth with an Up train - the large dairy was to the left.

Peter Kerslake says "Bailey Gate was the centre on the Somerset and Dorset line for a substantial amount of milk traffic with a thriving dairy and milk processing plant close to the station, situated at the southernmost section of the line.
Milk tanks were worked from and into the dairy sidings and the rakes of filled tanks were invariably handled by locomotives returning from earlier passenger workings, although on Summer Saturdays when passenger traffic was heavy the loaded tank wagons were often added to the rear of a northbound passenger working to Bristol Temple Meads.
Standard 92233 depicted here at Bailey Gate was one of the number of Standard Class Nine's deployed on the Somerset and Dorset network following initial trials with 92204 begun in late March of 1960 in an effort to reduce the amount of Double Heading by older Somerset and Dorset locomotives, especially on the busy Summer Saturdays with many long distance passenger workings , the Standards being considered capable of handling such traffic without the need of a pilot engine.
92204 was joined by sister engines 92203, 92205 and 92206 for the 1960 Summer workings, with the number being increased during the following two years."
