An image processing apparatus in which the reusability of digital image data is improved is disclosed. Dramatically reduced operating temperatures are provided at substantially increased power levels thus providing both improved lighting and improved operating life of the electronic components. The interface system determines the present operational mode of the wayside device and independently communicates information relating to the determined present operational mode to the vehicle control system. The unaltered replication of the requested data includes an unaltered replication of metadata associated with the requested data.
