Set in Concrete

Tuesday 8th August

Five of us off from Winchcombe to Broadway today with the main objective of setting a vertical pulley wheel on a new concrete block at the base of signal 39 (end of platform 2 north) - hope I'm not going to get my norths and souths mixed up this week!
This pulley will re-direct the signal wire from the balance weight arm of the ground  (shunt) signal through 90 Deg towards the track. First a bit of pick-axing and digging to remove some stubborn ash sapling roots (of which there are many on this embankment) - must say the task has been made much easier following a major embankment clearing job by the Broadway group last week.

and then with a bit of on the spot shuttering in place the "pouring" of the concrete followed. It took 5 large barrow loads to fill it. Jim P is on the shovel here

The pulley is mounted on a fabricated bracket which is pressed into the concrete, it sits on a small wooden frame to prevent it sinking any further than the desired height.

The alignment and clearances were then checked using a length of rope. 

Them back to the signal box for a few more tasks. The cabinet I mentioned in last week's blog has now got some substantial shelves fitted. Jim P, Richard C and Peter B exercised their carpentry skills in sawing, drilling and screwing. We now have an enviable storage facility!


Meanwhile I walked off south to the wooden post to finish off its waterproofing with a liberal coating of black sealant round the top of the steel boot 

An update on the locking system under the box. John P and Malcolm have fittted the missing locking tray so we now have a full set. 

 Malcolm is now pushing on with the lengthy process of fitting locking bars, cutting slots, drilling and tapping to attach the brass locks, etc, etc. I will attempt to explain an example of what is going on here.  A-channel locking (the row at the very top of the trays) means that when lever no.2 is pulled (route indicator signal) this locks all levers of opposing signals coming in from Toddington, and locks the FPL and point levers - we tried this out and it works - quite a jigsaw - glad Malcolm is on the case!
Here is a close-up  of the Lock for lever 2 on A-channel

You will note that there are some redundant slots on these tappet blades from a previous "life" - some new slots will require cutting in  different positions. 

While I'm in the explaining mood here is the extent of the signalling installation that we will be putting in at Broadway for the current layout. You should all be familiar  with the north end by now, but the  additional signalling up there will be a double  ground signal  at the route indicator  and one in the 6ft.  north of the points. 

Going south, the platform 2 starter will be the LH arm of the existing bracket signal (the RH arm will be taken off).  

 Platform 1starter is the wooden post.

Then there will be a new bracket signal approx 100yards south of Evesham Road Bridge with 2arms and 2call-on arms for the approach from Toddington.

Then an Advanced Starter Signal just north of Childswickham bridge.

An Outer Home Signal 720 yards south of the box 

A Working Distant Signal (motor operated) a further 600 yards south 

So in summary, we  have one bracket, 3 posts and 3 ground signals still to instal. Plenty to be going at.

A Bit More Finishing off

Tuesday 1st August

Just a very short blog today. Several more things to do to the signals at Broadway. Signal 39 (platform 1 north) needed a bit of fettling. Malcolm did a trial fitting of the disc to the ground signal to ensure that the red stripe was exactly horizontal - luckily OK ( sorry no picture as I was up on top of the wooden signal at the north end). The disc won't be left on until the signal is fully operational.
Then out with the paint brushes to touch up bits of scuffing, bolts, etc. And finally removal of the scaffolding - any further work up top can be accessed via the signal's ladder. Here's the finished job (well almost)

Bit more touching up of the paintwork on no.38 opposite and here are the pair waiting to control the headshunt and siding

There will be some further work required here at no.39 to instal vertical pulley wheels to orientate the signal wires to the correct alignment - another concrete block to cast!

Meanwhile back at the south end we are giving the wooden post another coat of white gloss - this is the fifth coat of paint it has had now so should be well protected. Keith L makes a start at the top - having got up there we saw that the safety hoop needed a top coat of black gloss - what shall we do first , black or white?!

Hope to get a picture of the finished signal next week with scaffolding removed.

Finally, Carl S has acquired a large metal cabinet which we have manhandled into the locking room. This will be used for the storage of tooling. It is extremely useful to have a kit of basic tools at each signal box.
