Describes the invention by Wynford Brierly of the 'Brierly apparatus', which holds out the prospect of improved safety on the railway system. The apparatus is 'as simple as anything of this kind can well be' and consists of a 'contact bar [...] mounted on the end of the rails on a rocking shaft, and [...] connected by a lever and wire to the ordinary signal connection, so that when the signal is put to danger by the man in the signal-box he also raises the contact bar into a position to strike a lever affixed to the engine. The blow, when it takes place, makes a complete electric current, sets an alarm bell ringing on the engine and works an indicator'. Also reports that 'Trials have been made on an express train on the Great Northern Railway for many months with the apparatus, and with complete success'.
