Classification Yard Switching Systems TRIZ Cases

A split-floor replacement case and temporary support frame let railroad instrument cases be changed without disconnecting wiring or causing downtime.

A shared RF channel with CSMA/CA cuts idle airtime in locomotive remote control and lets more locomotives and repeaters use limited spectrum.

A secondary OCU lock command blocks locomotive motion while preserving core functions, reducing accidental movement during maintenance.

A timed multi-input unlock sequence keeps locomotive motion controls disabled during servicing while preserving core remote functions.

Thermal imaging tracks railcar wheel heat to flag misapplied brakes in classification yards, helping prevent stalls, collisions, and derailments.

Wireless ad-hoc train grouping replaces physical coupling to raise heavy-haul capacity, cut marshalling time, and avoid long-track expansion.
