DEVELOPMENT OF BALLASTED TRACK WITH RESILIENT TIES

To minimize maintenance for ballasted track, it has been determined that that track structure must have a lower spring constant. To achieve this, JNR has adopted elastic rail fasteners, used resilient pads under concrete cross ties, and installed resilient mats under the ballast. As an alternative to pads under the ties, JNR has now experimented with the coating of sides and bottoms of the ties with a resilient resin. The proper track stiffness has been achieved and noise and vibration reduced, but the resin itself has proved costly.
