August 2009 S&T Report
article by: Andy Protherough
Week ending 8th August
With the refurbishment of the wooden centre pivot arm for
Toddingtons signal T20 not quite complete, the only work carried
out to this signal was the removal of the original spec plate. This
will allow the correct spec plate to align with the centre pivot
arm.
To complete the groundframe at the headshunt, myself and John P
cut, drilled and bolted down the timber flooring. Once fitted, a
generous final coat of wood preservative was applied to all the
woodwork.
On the opposite (Malvern) side of the track, two lengths of
signal wire were rolled out from signal T4 back to the south end of
platform 1. One will operate signal T4, the other will operate a
shunt signal to be placed at the foot of T4. With one wire attached
to the balance arm of T4, it was pulled taught to find its natural
alignment and metal stakes dug and concreted into the ballast at
approx. 7m intervals. Each stake was then fitted with a double
pulley wheel casting and the signal wires pulled through.
During Thursday, Neil Carr connected the electrics to both
signals back to the lineside cabinet leaving just a final
connection to be made once the arm has been fitted to signal
T20.
Work in Toddington 'box has progressed well with the most
noteable alteration being the modification of lever 31, and the
fitting of two new levers 32 + 33 along with the associated lever
and cam couplings.
A start was also made on the refurb of six 25mph speed
restriction signs. Firstly with the aid of a wire brush attachment
to an angle grinder, all traces of paint and rust were removed
before given a coat of red oxide primer. Once finished in black and
yellow, these will grace the lineside around Gotherington and
Bishops Cleeve giving a more pleasing look than the temporary white
wooden signs in place now.
Week ending 15th August
One of the last few jobs remaining for Steve and his trusted
mini-digger at Toddington North is drain clearing. S & T have
been assisting with this task recently so as to hasten the final
movement of vehicles lineside around this area. This will enable
the fitting of more vulnerable pieces of equipment that don't stand
up very well to abuse from wheeled or tracked vehicles.
These drains run the length of our railway approx. 5' from the
outside running rail and approx. 4' deep. At approx. 90' intervals
are inspection chambers made up from concrete rings with two
concrete lids and a metal grid across the top. Most of these
chambers have missing or broken rings and lids which have to be
replaced once any accumulation of ballast and other rubbish has
been cleared from the waterway below.
At last the wooden centre pivot arm was fitted to signal T20 along
with its spec plate, downrod and balance weight arm. A new signal
wire was then fed through the pulley wheel casts back to the north
end of platform 2. When signal T20 is commissioned next week, this
wire will be connected to the original wire from signal T6 which
stands at the very end of the platform 2. (T6 will then be stripped
of its fittings and the post completely removed). A final coat of
white and black paint is applied to post and fittings, and the
scaffolding removed.
Another task S & T have been helping with is the removal of
excess ballast dropped by the p/way train on the new track
formation north of the Stow Road Bridge. This has been good
exercise and a way of shifting a few excess lbs around the
waistline at the same time as helping out another very busy
department. Thanks go to Carl Smart and John P. in helping me with
this task.
After another visit to the NHS by the tamping machine, longer
lengths of point rodding had to be inserted to the ground frame
main point and FPL. This was required after the track was slewed
approx. 8 inches by the tamper to get a better line through the
curve.
Week ending 22nd August
Malcolm and Neil spent Monday supervising the tamper on
Gotherington loop. While there, time was also spent oiling and
greasing the many signal fittings and wheels around the
Gotherington area, many of which have not seen any use since being
put in.
At the foot of Toddingtons signals T4 & T20 will be a
shunting signal. To site these, a three foot square concrete pad
has to be constructed. This task was completed by Carl, John N,
Richard C and John P. Once filled, a timber template with four 10"
long bolts fixed in holes corresponding to fixing holes in the
baseplate of each dummy signal is carefully sunk into the wet
concrete. These will be left to cure for a week before fitting the
signals.
While the first train of the day was on its way to Cheltenham,
Neil makes the last electrical connections to signals T4 & T20.
The track circuits are extended from the original signals T4 &
T6 at the platform ends up to the insulated joints at signals T4
& T20. By the time the train returns to Toddington, the old
signals on the platform are decommissioned and the new signals
commissioned much to the surprise of the loco crew!
Further up the line just past the NHS turnout, Steve and his
mini-digger are tasked with digging a hole 7'x7'x6' deep. This will
be filled with concrete upon which will stand the bracket signal
which has undergone extensive refurbishment at Winchcombe. This
signal was recovered from Abercynon, South Wales during
resignalling of that line by Network Rail.
Week ending 29th August
Tuesday, and the hole dug by the mini-digger last week has now
to be filled with concrete. Brought up by the railcar from
Winchcombe on two trailers, are 7 tons of aggregate, 30 bags of
cement and plenty of water. Unfortunately the hole looks a lot
bigger than we expected, and when measured, we find it is actually
10'x8'x7' deep. We think Steve should have gone to
Specsavers…..never mind, it'll be alright!
With two 120ltr cement mixers set up at the rail side, John P on
the trailer shoveling ballast, Neil and Malcolm adding the cement
and water and tipping the mix into the hole, it was soon apparent
we were going to run short of materials. A decision was made to
build some shuttering to form a plinth 4'x4' in the centre of the
hole and fill this and then return on Thursday with more materials
to fill the remainder of the hole.
Using an online aggregate calculator later that evening gave an
indication that we would require a total of 15 tons of concrete to
fill the hole completely, so an order was placed for a further 8
tons of ballast and 20 bags of cement.
Returning Thursday, by 2pm the job was complete. Before the
concrete had started to set we sunk four 15" long bolts for the
bracket signal and four 8" bolts for a shunting signal allowing
approx. 2" to protrude above the surface. This will now be left for
a few weeks to cure while we finish off with drain repairs, and
installing three more signal posts out towards Stanway viaduct. We
will hopefully return towards the end of next month / October with
the road/railer machine and lift the bracket signal onto its
plinth. Once in position and all the fittings are attached, the
signal wires that operate the route indicator signal will be
detached, extended under and alongside the running line to connect
with the bracket signal. The route indicator signal will then be
removed and taken back to Winchcombe for refurbishment. This may
well find a home at Broadway in the future.
The shunting signal at the base of signal T20 was also fitted to
its concrete block.
In all, August appears to have been a very fruitful month with a
lot of refurbished equipment at last going into service. Toddington
north now looks part of an established working railway with just a
little work left to do by the p/way department to correct the
alignment of the running line into platform 2 off the turnout.
It is very satisfying to see the hard work put in by the
Winchcombe gang being put into service, after many hours of
releasing seized parts, removing years of grime, oil and paint and
turning out a quality finished product to enhance and help our
railway grow. WELL DONE to you all.
