§ Mr. CAVEasked the President of the Board of Trade whether the provision on railways of fly-overs and fly-unders as a means of clearing the main lines of local and goods trains, and so avoiding accidents, was first proposed by Dr. Biddle in the year 1878; whether this expedient has been adopted on certain lines and has been found of service during the War; whether he will grant a Return of the places at which it has been adopted; and whether its adoption is encouraged by the Board of Trade?
§ Mr. PRETYMANWorks of this character are in use on a number of railways, but I am unable to say when or in what circumstances they were first introduced. I do not think that the Return suggested would be of sufficient utility to justify the labour involved in preparing it.
