This was the opposite of the arrangement preferred by the Board of Trade ('automatic continuous brakes') in which brakes were held off by vacuum (or compressed air) generated by the engine, so that on loss of vacuum (e.g. from a leaky connection or a connection parting) the brakes came on automatically. The two brake vans, however, (one immediately behind the engine tender, the other at the rear of the train) also had hand-operated brakes, each under the control of a guard. These were applied.
