Abstract
In order to inspect the condition of tracks, which support railway cars, track
irregularity is measured four times a year along conventional lines by track
inspection cars, called \“East-i”. Track irregularity and the track materials that
cannot be inspected with the track inspection car are regularly inspected by track
patrolling on foot and/or using hand-held type inspection instruments. With the
purpose of reducing track patrol labor and maintenance costs, as well as to
improve inspection quality, we have been developing a track monitoring system
that is installed on a commercial car and monitors the track with greater
frequency. This paper provides the outline for a track measurement device that
uses the inertial mid-chord offset method and a track-material monitoring device,
both of which have been developed to monitor the track, and presents the results
of installing these devices on the multipurpose experimental train (called \“MUETrain”)
on conventional lines.
Keywords: track monitoring system, inertial mid-chord offset method, trackmaterial
monitoring device, multipurpose experimental train.
1 Introduction
Tracks are composed of rails, sleepers, ballast, and other materials. Track
irregularity advances and track material deteriorate as a result of repeated car
load and severe environmental conditions. So, it is important to monitor, inspect
and understand track irregularity and the degree and process of deterioration of
track materials.
In order to inspect track conditions, track irregularity is measured four times a
year along conventional lines in East Japan Railway Company by track
