Manufacturer and Builder 5, 1883
A railway carriage painted inside with the Balmain phosphorescent paint is included in one of the trains between London and Rotherhithe via the Thames tunnel. Although only one-hald of the available space of the carriage is painted, the phosphorescent light is quite sufficient to enable the passengers to distinguish small objects when passing through the tunnel; and, moreover, the light is powerful enough to enable a person to read the indication of an ordinary watch. It is probable that the railway companies will be en abled to effect a considerable saving in gas and oil by using the phosphorescent paint.
