Track center distance measuring device

(57) Abstract: OBJECTIVE regardless of the manual, to allow to the system a series of operations to determine from the measurement. [Configuration] with drivable measuring carriage on the rail, is attached to the measuring carriage has wheels for rails and engage the distal end extends to the adjacent line, a measuring bar which expands and contracts depending on the distance change between the adjacent lines , incorporated into the measuring bar, and a tape measure to detect the amount of expansion or contraction of the measuring rod is mounted on a measuring carriage, characterized by comprising a data processing recording means the value measured by the measuring tape is inputted.
