A six-wheel milk tank wagon stands in the siding alongside
the Creamery whilst in the background in the loading bay, milk churns can also
be seen. The six-wheel milk tank wagon was rated for use attached to an express
passenger train reflecting the need to move such traffic quickly whilst the
milk was fresh. Over the bufferbeam the pipe which drained the milk can be seen
controlled by the handle immediately above. Milk was loaded through the access
hole at the top of the tank accessed by the ladder. Milk Tank Wagons were a
common sight on Railways in the United Kingdom from the early 1930s to the late
1960s. Introduced to transport raw milk from creameries to food processing
units in remote locations, British Railways Milk Trains were the last
railway-based system before the mass-introduction of pasteurization and
resultant industry use of road transport. Post grouping in 1923, of the
282,000,000 imperial gallons of milk transported by rail by all four national
railways companies, the Great Western Railway had the largest share of milk
traffic, serving the rural and highly agricultural West of England and South
Wales. The LMS was the second largest transporter of milk (particularly from
the Lake District and North Wales), then the Southern Railway (particularly
from the Somerset and Dorset Railway), and finally the LNER from East
Anglia.
From 1937 the creamery at Moreton-in-Marsh was owned by
United Dairies (Wholesale) Co Ltd and the tank on this six-wheel milk tank
wagon is branded with their name. The cork insulated 3,000 gallon glass lined,
steel tanks were provided by the individual Dairy companies, while the
six-wheel wagon underframes were built by the Railway companies. The wagon
underframe in this picture is believed to have been built by the Southern
Railway to their diagram 3159. These were rebuilds from earlier four-wheeled
wagon underframes and retained the curved saddle fixings, which sloped the tank
to aid discharge. United Dairies had wagon underframes from all the big four
railway companies and the table below lists the twenty-eight built for them by
the Southern Railway:
