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.

RTRI Develops Snow Accretion Simulator
RTRI developed the first snow accretion simulator in Japan. This simulator is capable of precisely reproducing the process of snow accretion onto train bogies by computing and the phenomenon can be analyzed under conditions close to actual train running including snowfall and wind intensity. This new device will be used to develop vehicles preventing snow accretion more effectively.

RTRI Develops Facility Gauge Measuring Equipment
RTRI developed a device to detect trackside facilities protruding into the track clearance (Fig. 1). This device is capable of checking continuously whether any trackside objects interrupt safe train running or not without manual measurement nor using a specialized measuring vehicle.

High-speed Wheelset Test Rig Completed
On February 26, 2021, a new test rig was completed at RTRI. This test stand is capable of reproducing high-speed train running (maximum 500 km/h) and the load acting to the bogie (Fig.1 and 2), and, with this rig, durability and performance of Shinkansen’s wheel and axle can be evaluated. It will be utilized to evaluate the durability of wheelset and bogie parts and to analyze the mechanism of wheelset damage development.
