Train wheel bearing temperature detection

A method for determining a condition of a rail vehicle undercarriage component exhibiting a scanned waveform signature corresponding to a type of the component In response to being scanned by a sensor, the method comprising:

• acquiring scanned waveform signature data corresponding to a rail vehicle undercarriage component being scanned by a sensor;
• identifying a type of the rail vehicle undercarriage component based on the received scanned waveform signature data;
• and
• processing the acquired scanned waveform signature data to determine a condition of the component based on an identified type of component.

Computer readable media containing program instructions for determining a condition of a rail vehicle undercarriage component exhibiting a scanned waveform signature corresponding to a type of the component in response to being scanned by a sensor, the computer readable media comprising:

• a computer program code for acquiring scanned waveform signature data corresponding to a rail vehicle undercarriage component being scanned by a sensor;
• a computer program code for identifying a type of the rail vehicle undercarriage component based on the received scanned waveform signature data;
• and
• a computer program code for processing the acquired scanned waveform signature data to determine a condition of the component based on an identified type of component

A method for determining a condition of a rail vehicle undercarriage component comprising:

• scanning a rail vehicle undercarriage component with an array of sensors, each sensor aimed at a different region of a scanned target area of the component, to generate respective scanned waveform signature data corresponding to each different region;
• processing the data to identify a type of the rail vehicle undercarriage component being scanned;
• and
• filtering the data according to an identified type of the component to remove information not characteristic of the identified type.

A suspension apparatus for a hollow railway sleeper housing rail wheel undercarriage sensing equipment, the sleeper having a shell defining an equipment suspension cavity;

• a cover enclosing the equipment suspension cavity;
• and an equipment carrier disposed within the cavity, the suspension apparatus comprising:
• a cover attachment portion for attachment to the cover;
• an equipment carder attachment portion spaced away from the cover attachment portion for attachment to the equipment carrier;
• and
• a deformable element disposed between the cover attachment portion and the equipment carrier attachment portion for allowing relative movement between the cover and the equipment carrier so that the equipment carrier is isolated from vibration and shock imparted to the sleeper.
