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. 



  1. Very interesting, and well supported with pictures, blog as usual. Looks like you have your work cut out for you. Hope the weather is fine for the signal planting. Regards, Paul.

  2. Do you have the signals ready to be installed for the next phase south of the bridge? regards Graham

    1. Yes and no. The single signal posts are all painted up and ready. We have all the re-conditioned fittings including ladders, etc. The bracket signal will require a bit more sorting out from parts that we need to clean up and assemble at Winchcombe. It's all on the list!

  3. Please note:- two ls in the verb ' install'
    Since this is a British railway we might as well fly the flag a bit,eh chaps?

    Comes from the Latin but Roman Signal Stations were a bit different from ours.
    And no tea, either.
