Following
the restoration of the Anderton Boat Lift and the completion of
the new Falkirk Wheel, there are now plans afoot to restore another
‘boat-lifting wonder’ of the waterway age - the Inclined
Plane at Foxton, Leicestershire, a Scheduled Ancient Monument. Alan
Barnes looks at the exciting plans.
A
few miles to the south of Leicester, the route of the Grand Union
Canal passes close to the small village of Foxton where a flight
of ten locks raises the level of the canal by some 75ft. Built in
1810, these locks are still an impressive sight today and on summer
Sundays attract large numbers of visitors to watch the colourful
canal boats as they make their way through the series of locks against
the backdrop of rolling Leicestershire countryside.
However, the lock flight is not the only attraction at Foxton. It
is also the site of the remains of the Foxton Inclined Plane, a
unique boat lift built between 1898-1900 in an attempt to improve
the flow of traffic along the canal. With increased competition
coming from the expansion of the railway network, anything that
could be done to speed up the passage of freight along the waterways
was given serious consideration. One of the larger operators, Fellowes
Morton & Clayton, wanted to increase the size of boats which
they used to move coal to London but the flight of locks at Foxton
not only limited their boat size but also took them some considerable
time to pass through.
Rather than re-engineer the entire flight, an alternative solution
to the problem was to build an inclined plane boat lift running
up the hill alongside the canal locks. This lift was eventually
designed by Gordon Cale Thomas and built by W. H. Gwynne of Hammersmith,
London.

in its former glory with a
boat and crew in each water-filled caisson. The
gradient of 1:4 gave a journey time of 12 minutes -
a vast improvement on the time taken to ascend the ten locks.

It was basically a very short railway with a gradient of 1:4 which
had eight sets of railway lines and on these tracks ran two large
tanks, or caissons, filled with water and capable of holding two
narrowboats or a single 50-ton barge. The water filled tanks measuring
80ft by 15ft balanced each other and the lift was powered by a 25hp
engine which gave a journey time of 12 minutes to take two boats
up and two boats down, a great improvement on the average time taken
to negotiate the locks. An additional advantage was the amount of
water which was conserved by using the lift, which hardly needed
any water at all, compared with the locks which needed 25,000 gallons
per boat passage.
A steam engine housed in a separate boiler house was used to overcome
friction and provide additional braking. This engine was also made
by Gwynnes and may well have been a stock item designed for driving
their centrifugal pumps or for use in large boats. It was a 25 hp
twin cylinder jet condensing unit but steam experts have suggested
that as the engine only ran for short eight minute bursts, the jet
condenser would never have come into operation.
The lift worked extremely well, but operationally it was destined
to be very shortlived as the locks further south at Watford Gap
were never widened and the hoped-for increased canal traffic failed
to materialise. In 1909 the locks themselves were refurbished for
night use and the canal operating companies which had already introduced
their ‘fly-run’ system. This involved the crews working
the boats non-stop, with crew members taking it in turns to sleep,
while the trips to and from London continued. This enabled the canals
to compete more successfully with the railways and the need for
the inclined plane reduced. As a result its use soon became uneconomic
and in 1911 the lift at Foxton was effectively mothballed with all
traffic going through the locks. eventually in 1928 all the machinery
was sold off for scrap and the lift was abandoned.
When constructed, the boat lift at Foxton was the biggest and most
modern ever built and although the Plane did not last any great
length of time, it did provide the basis for the design of future
boat lifts built all over Europe.
The locks are now a Grade II listed site while the remains of the
Inclined Plane are a Scheduled Ancient Monument. In 1989 the Foxton
Canal Museum was opened in the reconstructed boiler house and here
visitors can learn about the lift and the commercial canal operations
that existed in the area. Although the lift and its associated machinery
and plant have long since gone, there are still traces to be seen
but much of the site is now overgrown. The Foxton Inclined Plane
Trust who run the museum and their partners have undertaken feasibility
studies for the restoration of the lift although it would certainly
be a considerable undertaking. Cost estimates nearly 20 years ago
put a figure of £5m on such a project and now the venture
would probably involve expenditure of nearer £8m.
Parts of the work are fairly straightforward. The canal arm approaches
and basins for example, as techniques for basic canal restoration
are now very familiar. However, care will be needed to prevent any
leakage of water which may upset the stability of the steep slopes
of the Plane. A return to steam power may not be possible, due to
the unavailability of suitable steam plant, and although the restoration
group are a long way from final specifications, electrically powered
drives and winches seem to be the most likely option. However steam
has not yet been entirely ruled out and English Heritage has asked
the Partnership to continue their investigations and Kew Pumping
Station has expressed a willingness to build a replica engine.
Using the existing railway line foundations has also been ruled
out on the grounds not only of expense, but also the wish to preserve
the Victorian archaeology of the site. A possible solution is to
construct new foundations on deep piles with reinforced concrete
tops which would sit alongside the originals using a three track
system between the existing foundations or a four track system adjacent
to the original.
Studies have also concluded that the completion of the restoration
would add significantly to the tourism of the area attracting far
more visitors to Foxton Locks than there are at present. To cope
with this it has been recommended that a visitor centre also be
built to provide information and to generate income to finance the
running of the lift. This centre will have to be positioned carefully
to avoid impacting unduly on a listed site.
