British Rail The Scientific Services Division of the British Railways Board provides a service to British Rail for the disinfestation of all thirty-three British Transport hotels, and 340 catering outlets at 200 stations and depois. It also provides this service for British Rail’s hostels, warehouses storing infestable foodstuffs, and ships operating from Parkestone Quay. The total quantity of insecticide used in these locations during a twelve-month period in 1966-1967 is given in Table 14. The quantity of insecticide used on the ships and in warehouses storing food is unknown, but it is thought a significant proportion of the material was used in hotels, refreshment rooms, and canteens, where the risk of insect infestation requires the regular use of insecticides often in close proximity to areas of food preparation. The Scientific Services Division is also responsible for timber preservation in some areas on railway property. It is known that dieldrin, gamma-BHC, and pentachloro- phenol, were used for this purpose by the Division and by specialist contractors in 1967 but no records exist for the quantities used. Herbicides were applied extensively by special spray trains to keep most of the 475,000 acres of running lines and sidings of British Rail free from plant growth. Details of the quantities of each herbicide used were given to the Advisory Committee by the commercial organisations applying the materials, but only on the understanding that these details would not be revealed to third parties. It is, therefore, only possible to state the total weight of all active organic herbicide materials used for this purpose in 1967 was 94 tons. Table 14.
