The L&N Railroad has been inspecting track gage using a "high railer" outfitted with a mechanical feeler system. The high railer was able to inspect the track at moderate speeds and it carried a paint spray system to identify with colored stripes those portions of track that required maintenance attention. Because of the possible dynamic gage widening that could occur under a locomotive during certain train handling operations, the L&N Railroad suspected that the unloaded measurement provided by the high railer might not be indicative of the true dynamic gage. Therefore, the L&N undertook to outfit a locomotive with a measuring system which could measure gage in the vicinity of the wheels most likely to encounter dynamic gage widening. A non-contact gage measuring system was installed on an L&N locomotive by ENSCO, Inc. This system was very similar to the gage measuring system in use aboard the DOT test cars. The system employs capacitive proximity sensors. By mounting the sensors in the shadows of the wheel flanges, the sensors are well protected from damage and are in a location close to the very point of interest where dynamic widening is anticipated.
