Turnout Gauge Block

Turnout Gauge Blocks are reinforced high-toughness nylon positioning insulators customized for turnout switch & frog sections of high-speed, heavy haul and metro junction lines.

It bears intense reciprocating lateral impact from wheel flanges at turnout zones, locks precise guard rail & stock rail gauge, isolates stray current between rail and metal fasteners, avoids gauge deviation, signal short-circuit and turnout jamming faults, cuts frequent turnout overhaul & track circuit troubleshooting shutdown losses for junction railway safety sections.
