An early problem for the escapees was that most were unable to find the way into the railway station, until daylight revealed it was in a recess of the side wall to an underground pedestrian tunnel. Consequently, many of them missed their night time trains, and decided either to walk across country or wait on the platform in daylight. Another unanticipated problem was that this was the coldest March for thirty years, with snow up to five feet deep, so the escapees had no option but to leave the cover of woods and fields and stay on the roads.
