Plain Line Rail Pads

Used on sleepers as ‘rail pads’ (between the underside of the rail and the sleeper/chair/baseplate) or used as ‘baseplate pads’ between the chair /baseplate and the sleeper. Plain line simply refers to sections of railway track that does not have any junctions or crossings in it.

There are many types of plain line pads required around the world which are typically sold in large quantities. When you consider that one mile of track requires nearly 2,500 sleepers, this means that nearly 5,000 plain line pads are required.

12mm sample thickness
Baseplate pad providing a resilient interface between rail chairs or baseplates and concrete or steel sleepers. It is also used for continuous rail support in embedded rail systems. Where maximum electrical resistance is important the pad can be supplied with a 1mm thick highly insulating layer bonded to the top surface.

Used as a rail seat pad for use between fl at bottomed rails and wooden sleepers. The polychloroprene formulation gives resistance to timber preservatives.
FC105A More Info 90 1.00 N/A N/A Rail seating pad material originally developed for use as a continuous support strip on paved concrete track (PACT). It can also be used between either flat-bottomed rails and concrete sleepers or flat-bottomed rails and malleable iron or steel baseplates.
FC584 More Info 60 1.05 190
(20 - 80 kN at 1200 KN/min)
10mm sample thickness
N/A Used as a rail seat pad material, for use between either flat-bottomed rails and concrete sleepers or on malleable iron or steel baseplates. It is designed for maximum axle loads of 25 tonnes and speeds up to 250 KM/hr.
FC892 More Info 65 N/A N/A N/A FC892 can be used either as a baseplate pad or as continuous rail support between flat bottomed rail and concrete slab track. It is designed to have excellent resilience, damping and impact attenuation properties for axle loads up to 25 tonnes.
