Rail crossing road traffic warning lanterns are used in pairs at level crossings as "flashing red lights" to warn motorists of the approach to or presence on the crossing of a train. The optical performance of a warning lantern with 10V, 25w and 10V, 13w lamps was compared with that of a road traffic signal lantern with 250V, 100w and 12V, 25w lamps. It was concluded that (a) the 250V, 100w road traffic signal lantern is of superior performance (b) the 12V, 25w road traffic signal lantern is of inferior performance and (c) a road traffic signal lantern fitted with a 25w, halogen lamp may be of comparable performance relative to the 25w rail crossing warning lantern. However the latter may be of inadequate performance for its application and a better warning lantern is probably needed. Recommendations for further investigation of road/rail signal co-ordination and for field studies of rail crossing warning lantern performance are made. /Author/TRRL/
