Type I Fastening System
Features rail shoulders and bolts.
Known for having a lower safety margin and poor clamping force.
Often replaced by Type II to improve deficiencies.
Type II Fastening System
Incorporates rail shoulders and bolts.
Developed to address the shortcomings of Type I.
Offers improved strength margin safety factor and clamping force.
Type III Fastening System
Fastener without bolts and shoulders.
Widely used in current railway tracks.
Cannot adjust rail surface height and gauge, limiting its application.
Other Common Fasteners
WJ-7, WJ-8, etc.
These types of fastening systems play a crucial role in maintaining the stability and safety of the railway track by securing the rails to the underlying support structure.
