Brief History Of The Class.

The WT tank wagons were vehicles used for carrying water. Wagons used to carry water that could not be contaminated, such as drinking water, were labelled "Domestic Water Only".

The WT group was numbered 1 - 236, with additions in the 400 range during the 1950's. Numbers 1 to 180 were built 1902 - 1910. Numbers 181 onwards were converted from steam engine tenders and miscellaneous tank wagons.

At various times, tanks have been temporarily converted for other other traffic.
