A system for determining a location of a rail vehicle based on an radio frequency (RF) signal that includes at least one processor programmed or configured to determine that a first RF communication signal transmitted by a head of train (HOT) unit of a plurality of rail vehicles is received by an end of train (EOT) unit of the plurality of rail vehicles, determine whether a second RF communication signal transmitted by the HOT unit is received by the EOT unit during a time interval after a time at which the first RF communication signal was determined to be received by the EOT unit, and determine one or more locations of the plurality of rail vehicles based on determining that the second RF communication signal transmitted by the HOT unit is not received by the EOT unit during the time interval. A method and computer program product are also disclosed.
