Rail Signal Arrangement for a Rail Signaling System

摘要

A rail signal arrangement for a rail signaling system comprises a rail signal having a rail signal lamp including a plurality of light emitter sub-arrays each comprising a light emitter, wherein the light emitter sub-arrays are electrically connected in parallel. A control circuit is provided and configured to operate the rail signal lamp in response to operating instructions from a remote operations management system, detect the proportion of light emitter sub-arrays that are in an operable condition with a monitoring system, and provide a condition status signal to the remote operations management system in accordance with whether the proportion of light emitter sub-arrays in an operable condition meets a minimum threshold level.
