The Survey of Railway Bridges

0WING to the traffic and to the parapet being in the way, the problem of relating the survey line over a bridge with the line on the road below it cannot usually be solved by setting up a theodolite on the bridge itself. The author has therefore developed the following method and used it successfully at many bridges ranging in span from 40 feet to 100 feet in the course of an extensive survey of electrified railway having a very dense train service.
