RTRI Develops Ballast Inspection System Using Passing Sounds
RTRI developed a ballast inspection system. With this system, ballast conditions can be evaluated by analyzing the sound transmitted through ballasted trackbed (Fig. 1). This system makes it possible to judge the necessity of trackbed replacement based on scientific indices and it is expected that the efficiency in track maintenance will be improved.

New Embankment Repair Method Developed
RTRI Developed an early repair method and aseismic reinforcement method for the embankment damaged by rainfalls and earthquakes. By applying these methods, the performance of embankments will be improved, while work period and repair costs will be reduced.

Seismic Reinforcement Method for Deteriorated Steel Bridges Developed and Used on a Commercial Line
RTRI Developed an aseismic reinforcement method for steel bridges integrating steel girder, abutment and embankment (Fig. 1) and it has been applied to a commercial railway bridge. This method is particularly effective in reinforcing deteriorated steel bridges in urban areas where only little work space is available. Since this method does not require construction of a temporary track and only minimal under-bridge space is occupied during the reinforcement work, high seismic performance can be attained with a shorter construction period and smaller cost.

RTRI Develops a Dynamic Gauge and Twist Measurement Device TRACK2er
RTRI Developed a dynamic gauge and twist measurement device TRACK2er. This device is capable of measuring track displacement caused by passing trains. Since this device can be mounted on a maintenance vehicle instead of using a track inspection car, it is possible to measure track displacement more easily, with lower cost.
