The SR 25T `Pillbox' brake van was constructed around the mid 1930's and was an advance on an earlier shorter wheelbase van, being heavier with a better ride and more efficient hand braking system. Brake vans and their associated guards were a common site at the rear of goods trains and ensured that the hand brake was applied at the appropriate times(most wagons did not have vacuum braking or through brake lines controlled by the locomotive), for maintaining oil lamp based signals to the driver of the train, to station personnel and signalmen and to ensure the train was operating correctly ad safely from his vantage point (via especially constructed side duckets) at the rear of the train. This type of brake van operated until the 1950's and several examples survive into preservation.
