Our IBSR and IBRR systems
have been proven over 20
years in the operation of
high speed, heavy freight
transport and standard
railways in more than 40
countries worldwide .



SCHWIHAG slide baseplates are fitted with an inner
bracing system for stock rails (IBSR). Depending on
the position of the IBSR slide baseplate within the
switching device, SCHWIHAG´S spring clips SSb 2,
SSb 3 or SSb 4 can be used. For the outside of the stock
rail, the client’s preferred fastening system (e.g. SKL,
Pandrol, Nabla) can be applied. The same inner bracing
system for running rails (IBRR) can be fitted in the
crossing-check rail area.

All IBSR slide baseplates and slide plates can be finished
with a wax sealed, non-corrosive, lubrication-free
Molybdenum coating or equipped with a lubricationfree,
friction-free sliding insert made of CuSn8 F66-
bronze, with or without graphite discs.
These coatings or sliding inserts are in the heel of the
switch in combination with the SCHWIHAG roller plate
system. Here they reduce the break-off forces of the
switch points and improve the durability of the sliding
plates. The lubrication-free Molybdenum coatings or
sliding inserts, together with the roller plate system,
guarantee permanent low switch moving forces offering
greater longevity.
IBSR slide baseplates and IBRR check rail plates are
made of ductile cast iron, ready for installation. For
smaller projects and special installations, corresponding
die-cast slide plates and abutments are available
for the manufacture of welded plates to fit any track or
blade profile.
