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.

FC6	More Info	63	0.80	800 (0.128 - 1.128 MPa) 10mm sample thickness	1400 (0.128 - 1.128 MPa, 2Hz) 10mm sample thickness	Baseplate pad designed to provide a resilient interface between rail chairs or baseplate and concrete or steel sleepers. Where maximum electrical resistance is important, the pad can be supplied with a 1mm thick highly insulating layer bonded to the surface.
FC14	More Info	55	0.73	500 (0.128 - 1.128 MPa) 12mm sample thickness	920 (0.128 - 1.128 MPa, 2Hz) 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.
FC26	More Info	80	1.20	12000 (0.128 - 1.128 MPa) 5mm sample thickness	N/A	Specially formulated for use in maintenance bays and vehicle washing plants where heavy contamination with lubrication, fuel oils, cleaning chemicals and other aggressive contaminants is present.
FC104	More Info	48	0.78	315 (0.128 - 1.128 MPa) 16mm sample thickness	380 (0.128 - 1.128 MPa, 5Hz) 16mm sample thickness	Designed for use as a baseplate pad material, FC104 is used to reduce the transmission of vibration from the track to the concrete substrate. Where a very high level of electrical resistance is required, FC104 can be supplied integrally bonded to a highly insulating surface layer.
FC208	More Info	35	0.62	290 (0.128 - 1.128 MPa) 12mm sample thickness	400 (0.128 - 1.128 MPa, 2Hz) 12mm sample thickness	Designed for use as a baseplate pad material, FC208 is used to reduce the transmission of vibration from the track to the concrete substrate. Where a very high level of electrical resistance is required, FC208 can be supplied integrally bonded to a highly insulating surface layer.

FC9	More Info	70	1.15	480 (58.8 kN) 4.5mm sample thickness	880 (58.8 kN, 20Hz) 4.5mm sample thickness	Used as a rail seat pad for fitting between the rail and steel or concrete sleepers. It is recommended for use with axle loads up to 18 tonnes, but may be specified for main line axle loads up to 25 tonnes, depending on the track conditions.
FC20	More Info	75	1.22	450 (20 - 80 kN) 4.5mm sample thickness	790 (20 - 80 kN, 5Hz) 4.5mm sample thickness	Used as a rail seat pad for use between flat 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.
Micromax (Rail Pad)	More Info	53	0.97	140 (20-80 kN) 5.5mm sample thickness	260 (20-80 kN 5Hz) 5.5mm sample thickness	Reduces dynamic forces from the track into sleeper systems. In this way it is possible to give older sleeper designs modern levels of impact protection. Micro-max pads are also available for new build track.
Micromax (Baseplate)	More Info	50	N/A	48 (8 - 70.5 kN) 10mm sample thickness	60 (8 - 70.5 kN, 2Hz) 10mm sample thickness	Considerably reduces dynamic forces from the track into sleeper systems, and are suitable for both modern high speed systems and for upgrading older track designs.
