Abstract
A computer program product for a computer system including a processor, a display, a historical database, and a geographic database, for determining railway defects includes a computer readable memory including code that directs the processor to receive positional data and status data for a portion of a railway, code that directs the processor to retrieve historical status data for the portion of the railway in response to the positional data from the historical database, code that directs the processor to compare the historical status data to the status data to determine a defect for the portion of the railway, code that directs the processor to retrieve an image of a geographic region in response to the positional data from the geographic database, code that directs the processor to determine an icon in response to the defect, and code that directs the display to display the image of the geographic region and the icon for the defect.
