2. Fishplate - Wikipedia

   en.wikipedia.org/wiki/Fishplate

   A fishplate, splice bar or joint bar is a metal or composites connecting plate used to bolt the ends of two rails into a continuous track. The name is derived from fish , [ 1 ] a wooden reinforcement of a "built-up" ship's mast that helped round out its desired profile. [ 2 ]

3. Rail fastening system - Wikipedia

   en.wikipedia.org/wiki/Rail_fastening_system

   The earliest rail chairs, made of cast iron and introduced around 1800, were used to fix and support cast-iron rails at their ends; [2] they were also used to join adjacent rails. [ 35 ] In the 1830s rolled T-shaped (or single-flanged T parallel rail ) and I-shaped (or double-flanged T parallel or bullhead ) rails were introduced; both required ...

5. Rail profile - Wikipedia

   en.wikipedia.org/wiki/Rail_profile

   The joint where the ends of two rails are connected to each other is the weakest part of a rail line. The earliest iron rails were joined by a simple fishplate or bar of metal bolted through the web of the rail. Stronger methods of joining two rails together have been developed.

6. Bolted joint - Wikipedia

   en.wikipedia.org/wiki/Bolted_joint

   A bolted joint is one of the most common elements in construction and machine design. It consists of a male threaded fastener (e. g., a bolt) that captures and joins other parts, secured with a matching female screw thread. There are two main types of bolted joint designs: tension joints and shear joints.

7. Slip-critical joint - Wikipedia
