ABSTRACT:
A weigh section of a railway track consists of two unsupported spans of conventional rail, produced by removing two adjacent supporting ties for example. The span of the unsupported rails is approximately 64 inches, less than the minimum distance between adjacent axles of a railcar. Four strain gauges are mounted on the under surface of the unsupported rail span of each rail, the four gauges consisting of two pairs of outboard and inboard gauges located in respective halves of the unsupported span. The outputs of the four strain gauges for an unsupported span are summed by adding the outputs of the inboard gauges and subtracting the outputs of the outboard gauges. This sum produces a constant value representative of the load supported on the rail as the axle load moves between the two inboard gauges. A limit switch tripped by a wheel of each axle activates a computer. The computer accumulates a plurality of sum samples while an axle moves between the two inboard gauges, averages the sum samples to produce average load value for each axle of a car, and converts the accumulation of average values to the total car weight.
