Abstract
A method for detecting railway vacancy is provided. The method includes sensing, at a remote sensing unit positioned proximate to a railway, a presence of a railcar traversing the railway. The method also includes storing, in real-time, at the remote sensing unit, a sensing event indicative of the sensed presence of the railcar traversing the railway and transmitting, asynchronously from the time at which the presence of the railcar was sensed at the remote sensing unit, the stored sensing event to a master accumulation unit.
