Abstract
System and methods for detecting an operational status of a valve or passageway on a railway asset. The methods may comprise: resiliently biasing a magnet in a direction away from a wireless sensor node coupled to the passageway; determining that the passageway is in an open position when the wireless sensor node is neutrally polarized (the data collection device being neutrally polarized when the magnet is distant therefrom); causing the magnet to move in a direction towards the wireless sensor node responsive to a cover of the passageway being closed; and determining that the passageway is in a closed position when the wireless sensor node is magnetically polarized (the wireless sensor node being magnetically polarized when the magnet is proximate thereto).
