Systems and methods for assessing track condition

A system for measuring one or more parameters indicative of a condition of a track comprising one or more rails, the system comprising:

• a vehicle body providing a load;
• a first sensing apparatus configured to measure a position H1 of a surface of the one or more rails at a location located a first distance L1 from a load contact point for the load;
• and
• a second sensing apparatus configured to measure a position H2 of a surface of the one or more rails at a location located a second distance L2 from the load contact point for the load, wherein L1 is greater than L2.

A system comprising:

• A processor;
• and
• a memory storing instructions, which when executed by the processor, causes the system to:
• receive a first signal indicative of position H1 of a surface of a rail at a location X under a first load condition;
• receive a second signal indicative of position H2 of the surface of the rail at the location X under a second load condition, wherein the first load condition is different from the second load condition;
• determine ΔH, wherein ΔH=H1−H2 and wherein the ΔH indicates deformation of the rail;
• and
• determine a value indicative of local rail condition based on the ΔH.
