Signal Wire Re-route Continues
Tuesday 21st Feb
Today at Winchcombe we continued with the groundwork needed to re-route the signal wire to the outer home signal on the approach to Greet tunnel . This to free up access down the embankment to the trackbed south of the station.
Just to remind you this needs the installation of a vertical pulley wheel at the base of the signal , a horizontal crank and two horizontal pulley wheels.
So, stage one was to fill the hole we had previously dug at the base of the signal with concrete to mount the vertical pulley on its steel plate
We use a length of nylon rope to set the height so that the wire will clear the ballast under the rails
Opposite this on the other side of the track an angle crank on a steel plate bolted to two large concrete blocks has to be let into the ballast. Luckily we have the assistance of a mini digger to excavate a rather large hole to drop this assembly in.
Then a repeat of this for the second horizontal pulley on the opposite side of the track (this position is between the bracket signal and where the access track comes down the embankment)
(excuse my thumb!)
That concludes today's work .
Before we disconnect the existing signal wire we need to install a series of stakes along the opposite side of the track to carry the wire -a job for next time.
Just a quick review of last week. You will probably have heard that approval has been given for the construction of a proper workshop for the S * T Dept in Winchcombe yard (exciting news!). So there has been a significant effort (courtesy of Neil C with the telehandler to clear the site and relocate/scrap many pieces of railway "memorabilia" that have found their way to storage here over the years!
We look forward to a start of the earthworks

Routine Maintenance
Tuesday 17th Jan
Started on some of the maintenance activity today required in Winchcombe signal box.
Access to the cams, etc operated by the levers needs a removable section of the floor to be lifted. Malcolm W in the locking room below uses a broom handle to prise it up while 3 of us upstairs lift out.
John B then sets to with an oil can to lubricate as many parts that he can reach .
And then give the levers a few off/normal movements to get the oil into the less accessible places.
Tuesday 24 th Jan
Off to Cheltenham today for some more signal box maintenance.
Here's the gang ready to go.
The catch handle pivot pins on the levers are getting stiff with continued use so they need removing and lightly greasing. Some resisting split pins to remove first!
And a general clean up with emery paper to remove rust from the mating faces and a smearing of oil

Continuing Preparations
Tuesday 20th Dec
We continued today with the preparations for the re-routing of the signal wire to the advanced starter at Winchcombe. John P, John B and myself in attendance with Malcolm W.
We need to install a vertical pulley at the base of the signal to route the wire across the track . Here it is pre-assemled.
John P is drilling some holes in a piece of plate to fit some anchoring legs (4 lengths of screwed bar with bent ends) to secure it in a concrete block.
So... off we go for a walk up to the signal to dig a hole for the concrete . Some really sticky black clay here with a ballast topping - makes for some strenuous digging!
The base of ladders are normally secured in concrete - this one isn't but has a couple of rungs below ground. Anyway we have extended the hole to give it added security!
The angle crank you can see at the base of the post will become redundant and will be removed. We will make a new sling to connect directly to the balance weight arm.
Any further preparations here will have to wait until the closed season when we can disconnect the signal and gain access with the railcar to transport the heavy stuff - which we have already got ready as you can see here:
These two blocks holding the horizontal pulleys will be sunk into the ground - so more digging of ballast.
Also being prepared today is the 8ft long wire sling which will connect to the balance weight arm. The thimbles on each end are securely fixed in position using aluminum sleeves which are crimped with this tool - John B on the handles and Malcolm W on the ground (Sorry picture not terribly clear)
But here is the end result
So that will be it for this year . We have several signal restoration projects for next year some of which will require the erection of scaffolding. A new metal token exchange platform is in progress for Gotherington - there will be plenty to do. Not sure at the moment whether the plan to replace the bracket signal at Cheltenham will go ahead during the closed season - so the one we have prepared still languishes horizontally in the yard at Winchcombe.
I'll sign off now wishing you all Merry Christmas and, hopefully , a fulfilling New Year from GWSR S&T

Signal Wire Re-routing
Tuesday 29th Nov
It has been decided to re-route the signal wire to the advanced starter situated near the northern portal of Greet tunnel because it currently crosses the access road down the embankment and has to be disconnected when vehicular access is required. (this access road was prepared by the contractors to enable heavy plant to be brought in for the recent repairs to the embankment here at Winchcombe)
The existing stakes supporting the pulleys and wires will be replaced with new ones on the opposite side of the track. So starting adjacent to the bracket signal John P prepares to measure the distance up to the starter. This will enable us to determine the length of new signal wire we will need , including the additional length to cross under the track twice
At the starter signal we will need to bury the wire in a tube to allow vehicles to pass over, so to determine the heights required for the blocks for mounting horizontal pulleys - we check this using a piece of nylon rope passing under the track

Repairing the Crossing
Tuesday 11th Oct
A visit to Gotherington signal box today to replace some rotten planks in the foot crossing.
We were intending to catch the first Cheltenham bound train from Winchcombe but for some reason it was going to be significantly late so we got permission from Brian Nicholls to park up at Gotherington West.
There are several rotten boards in the crossing some more obvious than others until you stamp on them.
All the boards are covered in chicken wire to prevent slipping- and this is held down with many staples (to prevent tripping!). These are a pain to remove where they are well hammered in, but with four of us at it we son peeled it back.
Seven boards have been replaced and re-covered with wire. Should be safe for a few more years.
A bit of creosote required on a few ends that we had to trim. Left it for the Wednesday team!
