What is the Difference Between Insulated Joint and Glued Insulated Joint

Methods to insulate the track circuited section –

1. Insulated joints –

Track circuited sections are ‘insulated’ electrically from the track on either side by insulated joints. The standard insulated joint in normal use, is made out of ordinary fish-plates duly planed on the fishing planes for accommodating channel type insulation between rails and fish-plates with ferrules/ bushes over the fish bolts and end posts between the rail ends.

2. Glued insulated joint –

Glued insulated joint have been developed using resin adhesives. These joints consists of web filling fish plats glued to the rails with a high polymer adhesive and bolted with high tensile steel
