HoldFast panels are 1.8 metres to 5 metres
in length when positioned laterally along the track.
They consist of a cess panel (outside of the rail edge)
and two gauge panels (these sit in between the two rails).
The panels have been thoroughly tested and proven in
some of the most critical level crossing locations on
the UK rail network.
Heat Testing
Heat testing has been performed to satisfy the stringent
requirements set by London Underground Ltd (consisting
of Metronet SSL, Tubelines, BCV and of course LUL) to
gain a concession across the network (recently acquired
by HoldFast).
Crib Burn Test
This test has been conducted to BS5852 part 2. A number
7 wooden crib was charged with 5ml of alcohol and ignited
on a sample of crossing panel material. Temperature,
time and effect on panel mass were recorded, along with
area and depth of charred area.
Wet and Dry Skid Testing
The panels exceed the standards set out by Network Rail
relating to wet and dry skid testing. |
Within
these three panels, five lengths of aluminium supports
are laid longitudinally along the sleepers. These
are also at a predetermined length to provide adequate
support for the end of panels and to provide a manageable
length for the installation crews to cope with.
This means that sleepers can be left at their normal
random centres.
A
unique patented connection system has been developed
for these trials.
The
HRH system also includes side curbs (as seen on the
artist's impression on the front page), although these
have not been installed on the trial run.
