From
the station the line is planned to run south until it reaches
the Shepperton branch railway line where it will turn roughly
east (3). Route 1 then heads north along the old standard
gauge siding trackbed and crosses the Staines Aqueduct on the
old SG bridge, passes the Gauge House (shown in 4) and rejoins
the original trackbed (as shown in 6).
Route
2 continues eastward parallel to the Shepperton line for
another 150m or so before swinging roughly north east,
crossing the aqueduct on new bridge before joining the old
route (as shown in 7). Both these routes have been surveyed
but are less likely to be allowed than Route 3.Route 3
continues parallel to the Shepperton Line for approximately a
further 200m before crossing the aqueduct in the vicinity of
Bunny Lane (9). It may be possible to use the existing bridge
there (or part of it) to cross the aqueduct or it may require
a new bridge. There will also be a station here to serve the
Kempton Nature Reserve.
The
line will now enter a rather pleasant area alongside the
aqueduct (11 & 12) before dropping a little to go under
the Shepperton line (13). Here we encounter an engineering
problem. At some time since narrow gauge trains last ran the
bridge has been strengthened by fixing new beams underneath
the old ones, thus reducing the headroom by about a foot. This
leaves about 7 feet clearance from the concrete roadway. This
is not really sufficient so the options are either to build
special low height rolling stock or try to lower the trackbed.
Removing the beams is not thought to be an option.
There
is a steepish climb out from under the bridge (14) and that
will bring the line alongside the Red House Reservoir which is
a most delightful setting (15, 16, 17). fter about 200m the
line enters Hyde's field (18) and turns south away from the
Shepperton line to terminate by the Upper Sunbury Road. This
last section is now totally overgrown with quite mature trees
and will require a lot of clearing. One possibility here is to
have a continuous loop of track here so that the trains will
not have to be reversed.
Other
suggestions for the Kempton end have included running under
the A316 flyover to a station on the west side and running a
branch to Kempton Park station for the convenience of
passengers arriving by train. Both these are possibilities but
are not part of the initial plan. There could be all sorts
of variations as we not only have to satisfy the
requirements of Thames Water but also those required to get
planning permission.
It
is quite likely that at first the line will go no further than
Bunny Lane.
