In rail track system, railway fish plates are important components to joint two steel rails together. In a real world application, there are three commonly used types of railway fish plates:
- Bolted joints
- Compromise joints
- Insulated joints
In today's railroad construction, bonded insulated rail joints and polyurethane insulated rail joints are the two types widely used insulated rail joints.
Bonded insulated rail joints are mostly used to separate electric circuits in rails and turnouts. Because of widely used in continuously welded rails (CWR), the bonded insulated joints in rails must be ensured to transfer longitudinal forces arising in the rail tracks. And insulated joints can also cut in square or angular.
The typical features of bonded insulated rail joints：
- Up to 60' long and ensured the specified length
- Mostly used with A-490 bolts or huck pins (6 / 8)
- Conveniently used in worn rail or transition rail configurations
Micro alloy rail joint
The polyurethane insulated rail joints are featured to a micro alloy joint bar sections. Through ultraviolet, ozone, weathering abrasion, or the shock and flexing stresses of heavy rail traffic, it is a specially formulated compound. The dense polyurethane material bonded to the rail joints can provide superior insulation between the steel rails and the joints.
