14T Tank Wagon, United Daries – Era 3
<p>Up until the mid-nineteenth century much of London's milk was supplied by cows kept in cramped urban locations. This proved unhygienic and as a result of a cattle plague this practise diminished after 1865. Around about this time the milk started to be transported into London by rail on frequent express trains.<br><br>By the 1930s the volume of milk being transported had grown to a high enough volume that it was no longer deemed efficient to transport using traditional goods vehicles. As a result United Dairies ordered a series of tank wagons, with six-wheeled tankers proving to be the most effective design although four-wheeled wagons were also used. United Dairies ended up operating over three hundred such tank wagons.</p>
