The Corrugation Recording
Trolley is a lightweight, self-contained
instrument to measure the variation in
smoothness across a rail head, known as
corrugation. After a short digital set up
procedure, recording commences by simply pushing
the trolley along the track. All the recordings
are distance based, therefore the recording is
independent of the speed of travel along the
track. The CRT recording trolley produces
analogue traces on its integral 100 mm thermal
recorder to a selected distance base and also
records all the measurements simultaneously on a
PC memory card for further computer analysis.
