MODEL NO. 4127 SERIES RAIL TRACK GAUGE CONTROL RODS

The main cause of derailments in industrial rail yards is over-wide track gauge.
TEST, MEASUREMENT & DYNAMOMETERS
Locomotive and freight car wheels can exert as much as 1814kg of side pressure
against the rails. If the ties are spongy, they can lose their spike-holding strength and allow the rails to be
pushed over from wheel side pressure. A between-the-rails derailment requires cranelifting to put the car or
engine back on the rails and extensive track repair.
A pair of iron jaws at each end of the double-ended gauge rod grip the rail base to hold the rails to gauge and
keep the rails upright against wheel pressure.
For curved track, use the single-ended gauge rod. Jaws at one end attach to the base of the outer curved rail,
which receives the greatest wheel side pressure. The hook at the other end grabs the base of the inner rail.
A simple preventive measure for gauge spread is to install Aldon double-ended gauge control
rods every 2.4m in high traffic track. If your switches do not have gauge plates at the points end,
install a double-ended gauge rod at the approach to the switch as well.
