What railway fasteners are typically used together with rail elastic clips?

As the core fastening element, rail elastic clips need to work in synergy with various matching components to form a complete track fastening system.

This system typically includes key components such as baseplates, insulated gauge blocks, anchor bolts, and shoulder inserts. The baseplate is a crucial part placed between the rail and the sleeper, usually made of rubber or highly elastic polymer materials. Its main functions are to cushion wheel-rail impacts, provide electrical insulation, and adjust rail level. Depending on line requirements, baseplates can be categorized into various specifications like standard, vibration-damping, and level-adjusting types.

Insulated gauge blocks undertake the dual responsibility of maintaining gauge and providing electrical insulation within the system. These insulation components, made of engineering plastic, are precisely installed between the rail and the fastener, effectively preventing current leakage through the track while ensuring precise gauge dimensions between the rail and sleeper. In concrete sleeper applications, the system also includes anchor bolts and insulation sleeves embedded in the sleeper, forming a reliable anchoring combination that securely fixes the fastening system to the sleeper.

Matching components differ based on the type of sleeper foundation. On concrete sleepers, threaded rail spikes combined with embedded nylon sleeves are typically used, whereas in wooden sleeper applications, dog spikes or screw spikes are used for direct fixation.

Furthermore, joint fishplates are required at rail joints, and anti-creepers may need to be installed in special sections to enhance longitudinal resistance.
