A colleague on the NYMR PW has asked this question. Does anyone know of any other locations were "Special Brake pins" were used? When we took over the line in 1969, I noticed a line of brake pins on chains suspended below the down platform. At Goathland. On subsequently acquiring copy of BR (NER) York G1/283 ' Working of freight trains down steep gradients' it lists , in respect of the Goathland - Grosmont section, that 'special brake pins are provided, after they have been used, they must be returned to Goathland from Grosmont by first available means.' My question is simple - as all wagons have brake pins anyway, why did they need 'special' ones? To this untrained teenager at the time, the ones under the platform looked no different to the ones on the wagons anyway!
