V-Shaped Glued-Insulated Joint Rail

Kanto Bunkiki has developed a v-shaped glued-insulated joint rail, which is built to limit flaw generation,
and relatively reduce noise output and vibrations.

Lessen Noise Output and Limit Flaw Generation

The V-shaped glued-insulated joint rail is made by shaping an ordinary straight angle joint structure into a v shape. This enables the wheels to always be on the rail and pass straight over the joint sections.
This structure can lessen noise output and limit flaw generation.
Only the rail head is v-shaped, and the leg section is straight angled; so this structure can also help keep manufacturing costs down.
The V-shaped glued-insulated joint rail can be made as a 50 kgN rail and 60 kg rail.

Built to Limit Wheel Sinking

In an ordinary rail, the wheels tend to sink at the rail shape section. However, a v-shaped rail is built to always keep the wheels on the rail (gradual change over) and let them pass over the joints, which can lessen the occurrence of sinking.
This can also lessen noise output and limit flaw generation.

Same Strength as an Ordinary Rail

The v-shaped glued-insulated joint rail has the same strength as an ordinary rail, for both the teflon and non-teflon Holdtite applied types, and it also meets the JIS E 1125 standard.
