Types of railway Fastening System

N type fastener: This is a fastener system suitable for high-speed railway, its design takes into account the composition of fastener, assembly performance, technical requirements of parts and other aspects.
Elastic W-type fastener: Also as part of the high-speed rail fastener system, it also has specific technical requirements and standards.

WJ-7 fastener: As part of the TB/T 3395 standard, WJ-7 fastener has its specific technical specifications and application scenarios.
Type WJ-8 fastener: This is also a high-speed rail fastener system, which follows specific standards and specifies terminology, definitions, basic requirements, technical requirements, etc.

Plate ballastless track fastening system: With the rapid development of modern high-speed railway and urban rail transit, plate ballastless track has been widely used. This track structure has specific requirements for the fastener system, such as fastener stiffness and CA mortar thickness.
Fasteners for surface contact or embedded plate tracks: This fasteners system is suitable for specific track forms, such as those containing elastic supported concrete elements.
