Indigo is a powerful new tool for monitoring and maintaining track. It is a cost effective way of monitoring the track for faults and features that cause rough ride. Its accurate GPS can direct track maintenance staff to target problems quickly. This new approach to pre-emptive maintenance can prevent mild issues from developing into serious events that require the stopping of vehicle traffic.
An internal ARM processor monitors these sensors and when configurable thresholds are exceeded, an alarm is sent to the Indigo cloud server along with a snapshot of the raw data spanning the event. The Indigo cloud server collects events reported by all Indigo devices. By correlating data from different devices a high confidence can be placed on the location and severity of developing track faults.
