Structure of Turnouts
Turnouts Comprise an Enormous Number of Parts
Turnouts are made from rails and the many parts used to fasten them together.
This is why turnouts are developed and manufactured under a strict management system. The production process for turnouts can roughly be divided into development and design, processing of rails and parts, assembly, and inspection.
It is this meticulous work combined with advanced technologies that produce the high-precision products of Kanto Bunkiki.
