Watch VoirFilms. "Rail" captures British Railways at a major turning-point in its history. In certain respects, this was a period of considerable upheaval and loss. There was a facing-up to the increasing need for a big modernisation drive. Full and speedy electrification, or the wider promotion of diesel-power on remaining lines, became a matter of top priority. Geoffrey Jones recorded a rapidly disappearing world of everyday steam travel, with its labour-intensive rail workforce : some of the footage in "Rail" (recognisable from "Snow") dates from around 1962.
