Stablesoft equestrian flooring is
fitted on the deck, and mounting
blocks at the start of the ramps
encourage horse riders to
dismount and walk the horse
over. The bridge is due to open
at the end of July.
The three new MCBs, at
Morston Hall, Thorpe and
Levington, utilise Obstacle
Detection (OD) technology
comprising radar primary
obstacle detection (POD) -
the safety-critical component
required to detect objects
that would be a danger, such
as vehicles, people or large
animals - and Light Detection
and Ranging system (LiDAR) as
the complementary obstacle
detection (COD), to reduce
the risk of an object in the
crossing area below 500mm
from the road surface remaining
undetected.
In short, the COD uses
infra-red technology to detectobjects such as prone bodies
and small children in the space
below that covered by the
POD’s radar, which is mainly
looking for large objects.
The conversion of the existing
Westerfield AHBC is outside
the immediate area of the new
loop but will be affected by
the increase in freight traffic.
Increased road traffic resulting
from a new Ipswich Garden
Suburb Development of 3,500new homes in the vicinity of
Westerfield clinches the need
for conversion to MCB. The
configuration of the crossing in
relation to footpath ramps to
the platforms means that OD
may not operate reliably, so this
crossing will be MCB-CCTV.
The conversion of this
crossing will benefit Up East
Suffolk trains. Hitherto, most
Lowestoft to Ipswich trains that
are not scheduled to stop at
Westerfield have to pause in
the platform due to the lack of
‘non-stopping’ provision in the
controls of the existing AHBC.
This will, of course, be rectified
with separate ‘stopping/non-
stopping’ strike-in points for the
new MCB.
However, the ‘Auto Lower’
control (provided as standard
with ‘Auto Raise’ at all of
the new MCB crossings) at
Westerfield will not initially be
used, as there have been a
number of incidents including
blocking back over the crossing.
Red light violation cameras,
already in place at Westerfield,
have been installed at all the
new AHBC crossings.Colchester PSB
The signalling was controlled
from the Entrance-Exit (NX)
Ipswich panel. However, with
the addition of the Bacon
Factory curve in 1999, the
increase in freight traffic, and
an increase in passenger train
frequency in recent years on the
main line and East Suffolk lines,
the workload threshold has
been exceeded.
Operating Ipswich station can
be challenging if trains arrive| – | – | – | – | –- ^ - ^ - ^ - ^ - ^ - ^ - ^ - ^ - ^ - ^ - ^ - ^ - |
