A method and apparatus for determining the weight of a railway supported vehicle. A pair of spaced apart rails which are engageable with wheels of the vehicle are supported by a longitudinally extending sleeper or tie member which extends transversely to the rails and which is disposed beneath the rails and extends outwardly of both sides of the rails. The longitudinal end portions of the sleeper member which are disposed outwardly of the pair of spaced apart rails are supported in a manner which allows deflection of the sleeper member in response to forces applied thereto by the rails. A means is provided for providing a signal which varies as a function of the strain in the sleeper, which means preferably measures either the shear strain or the bending strain in the sleeper. The signal is then processed to provide an indication of the weight of the vehicle supported on the rails.
