Rail cant measurement tools and associated methods enable users to measure rail cant. The measurement tools comprise a reference assembly, and a cant angle measurement assembly. The reference assembly comprises a track plane reference bar, a rail centerline reference head, and a measurement gauge for measuring rail cant.

Rail cant measurement tool and method

A rail cant measurement tool and associated methods enable users to measure rail cant. The measurement tool comprises a reference assembly, and a cant angle measurement assembly. The reference assembly comprises a track plane reference bar. The cant angle measurement assembly comprises a web-engaging arm assembly, a spring-biased lock-release mechanism, a rail cant indicator, and a rail cant linear adjustment mechanism. The web-engaging arm assembly comprises pivot arms and web rollers. The pivot arms each comprise upper arm ends and lower arm ends. The upper arm ends are attached to the lock-release mechanism. The reference bar engages opposed rails and the cant angle measurement assembly engages a select rail of the opposed rails. The rail cant indicator indicates rail cant information as determined from the track reference plane and the running surface of the select rail.

A railroad car truck frame jack clamps a side frame, the clamps suspend a cross tube which in turn suspends one or more cylinders which raise a bolster plug thereby lifting the bolster relative to the side frame and decompressing the truck springs for repair or replacement, twisting loads being minimized in the preferred embodiment by a lost motion slot.

A motor vehicle body is adapted for use on railroad tracks by being elevated by 'high rail' unit steel wheels, but with the motive force being supplied by the vehicle's road wheels, a loaded gage axle assembly having vertical loads imposed by hydraulic rams, and horizontal loads being supplied by horizontal rams through split axles and steel wheels to the railroad tracks is calibrated to measure track strength and adapted to be operatively connected to electronic data recording and comparing apparatus.
