With the System, the user can write into the DD Memory any data unique to that specific point of track and deposit it at that point.
Vehicles such as measuring car, inspection car, snow-plow, etc., can read this data as they pass over the DD Memory and utilize it for their own purpose. The DD Reader and DD Signal Processor reads and analyzes the information memorized in DD Memory and transfers it to other equipment.
The DataDepot System has already been delivered to almost Japanese railway companies with quantities of more than 60,000 DD Memory (March, 2003).
