A suggestion in The Times of 10 October 1853, commenting on a train collision near Portarlington station, on the Great Southern and Western Railway, on 5 October that year, called for a paper-roll recorder, keeping a log of wheel revolutions against time, to be carried in a locked box on trains, the record to be removed and stored by station masters at the destination station.
