Abstract

A system for containing derailment of a railway vehicle from rails over which the railway vehicle moves. The derailment system includes a derailment apparatus provided on each side frame of the railway vehicle. In one instance, each derailment apparatus has inner and outer laterally spaced and free ended depending arms disposed above a head section of the rails as long as the railway vehicle wheels ride on the rails. In the event either wheel becomes derailed, one the rails is received and accommodated within a pocket defined by the respective derailment apparatus. When a derailment occurs, the depending arms of the derailment apparatus extend below and to opposed sides of the head section of a rail received and accommodated in the pocket of the respective derailment apparatus whereby inhibiting total derailment of the railway vehicle from the rails over which the railway vehicle is traveling.

Dependent claims

A system for containing derailment of a railway vehicle from a rail system including a pair of laterally spaced rails over which said railway vehicle travels, with each rail having a base section, an upstanding middle section joined to said base section and a head section joined to said middle section and having a predetermined width, and with said railway vehicle having a pair of laterally spaced side frames which mount wheels carried by axles for rotation about a fixed axis, with said derailment system comprising:

a derailment apparatus provided on each side frame, with each derailment apparatus having inner and outer laterally spaced and free ended arms arranged outboard of a respective wheel and depending from the respective side frame and disposed above the head section of the rails as long as said wheels ride on the head section of the rails, with the lateral spacing between said arms being equal to or greater than the predetermined width of the head section on either rail to define a pocket therebetween such that in the event either wheel becomes derailed one of the rails is received and accommodated within the pocket defined by the respective derailment apparatus, with the free-end of each depending arm of the derailment apparatus being adapted to extend below and to opposed sides of the head section of the rail accommodated in said pocket of the respective derailment apparatus whereby inhibiting total derailment of the railway vehicle from the rails over which the railway vehicle is traveling.

A system for containing derailment of a railway vehicle from a rail system including a pair of laterally spaced rails over which said railway vehicle travels, with each rail having a base section, an upstanding middle section joined to said base section and a head section joined to said middle section and having a predetermined width, and with said railway vehicle having a pair of laterally spaced side frames disposed toward opposed ends of said railway vehicle, with wheels carried by axles mounted by said side frame for rotation about a fixed axis, with said derailment system comprising:

a derailment apparatus provided on each side frame, with each derailment apparatus having inner and outer laterally spaced and rigid free-ended arms disposed above the head section of the rails as along as the wheels ride along said rails and extending lengthwise of the respective side frame, with the lateral spacing between said arms being equal to or greater than the predetermined width of the head section on either rail, and with at least one of the inner arm and outer arm of each derailment apparatus having a generally horizontal free-ended component which is adapted to be operably disposed beneath the head section of the adjacent rail in the event a wheel drops off a rail whereby inhibiting total derailment of the railway vehicle from the rails over which the railway vehicle is traveling.
