Tuesday 10th March
A great turn out today with 10 of us attending at the S & T workshop at Winchcombe for what was to be a day of demonstration, fault finding procedures and education.
Initially Peter W presented a slide show to explain how the electrical circuitry of token machines worked:
And then a practical demo of the machines in action. To do this a pair of the token machines have been wired up to operate on the bench and Peter W and Andy D volunteering to be the signalman at Winchcombe and Cheltenham to show how the tokens worked in practice.
With a very interested audience!
And as if that wasn't enough excitement , there followed an equally interesting presentation on telephone technology given by Mike S on the BT 700 handsets used on the railway and how to maintain them.
Then off to Winchcombe signal box locking room where a Strowger " telephone exchange" is installed for a working demo
We now have a lot of electrical knowledge between us, boosted by our new recruits Martin H and Mike C - this bodes well for fault finding in the many and varied systems on the railway. Kevern O continues with the setting up of the acceptance lever system between Toddington and Broadway and a SPAD warning system. More on this in the future when I understand a bit more about it!
I have been a bit tardy in publishing the previous weeks work so here is a brief summary of March 3rd.
A bit of Finishing Off at Cheltenham with a good turn out with 8 of us. Some work still to do at the new pointwork to set up the detector linkages to the point motor
Peter W checking that we have power to the unit
And two more bits of track bonding to finish off - Martin on the drill unit
The electrical work has now been completed and all the stage one cabling replacement project is complete. Testing has been carried out and, except for a few small problems which have been ironed out, all is working well.
Congratulations to all involved for carrying out a complicated project which was completed on time for the new running season.

PS
While we were in the Winchcombe locking room being Stoweraged I took a photo of the locking trays which I think you will find interesting - here is a fine example of the mechanical lever locking that keeps the signalling safe. Worthy of a bit more training for us here to understand all the interlocking sequences - one for the future!
Note the electrical locks connected below.








"as if that wasn't enough excitement" - I love the droll sense of humour!
ReplyDeleteExcellent update. Thanks. Well done on the work at CRC and Winchcombe.
ReplyDeleteInteresting to read that the acceptance lever system for the Todd Broadway line is getting the attention.
Regards, Paul.
Current practice is to paint the covers of the Lever Locks, Circuit Controllers and Contact Boxes Blue. They look very smart, maybe a project for a rainy day!
