Signal box was opened for the last time at 2335hrs Saturday 7th January 2017 in readiness for a T3 possession booked between Saltney Junction and Llandudno Junction. All signals removed as per Section C except for the up and down distant signals which were bagged over after switching power off.



ABERGELE (ABOLITION OF THE DOWN LOOP)

I WAS ON DUTY AT THIS BOX 0010 - 1000 (Sunday)

Last passenger train to call at Down Loop platform was 1W98 1934 Cardiff Central - Llandudno Junction due 2317hrs

T3 Possession of lines between Llandudno Junction - Rhyl taken at 2359 (extended to Saltney Junction at 0218hrs (Saturday 7th to Monday 9th January 2017)

Point rodding to Points 26 and 37 and also FPL 25 disconnected at 0009hrs (Points barred over and clipped and scotched for engineering trains to travel over down loop)

Power/ light indicators disconnected on signal AE10 and arm removed at 0021hrs

Power/light indicators disconnected on signal AE3 and arm removed at 0100hrs

Catch handles disconnected and removed 0145hrs - 0220hrs. Levers 4,10,26,37 disconnected normal. Lever 25 FPL disconnected in reverse (to become an interlocking lever.

Engineering trains 6W01,6W02,6W03,6W04 and 6Y50 - the first four through down loop. Also a tamper for the finishing job.



Engineering work overran due to drainage problems and actually finished at 0843hrs on Monday 9th January causing some severe disruptions along the coast.

Down Main into use between points 26 and 37 as from 0843hrs

Down loop finally lifted through the platform during Monday night possession.

No down trains calling at Abergele until FURNO - approx. last week in February while the platform is extended and built over the site of the down loop.

I take it from the above and this picture (click on it to go to the larger original):

that the Down main is staying where it is and the platform is being extended forward over the site of the loop to meet the main line? Out of curiosity why wasn't the main line simply diverted through to the platform? (Other photos indicate there is plenty of room each side of the station to make a gradual transition in place of the points off the mainline.)

For a bonus, a close-up of the box:

This would seem the obvious answer. The new down main does take an even better alignment through what will be the new platform. An expensive way of going about thing's i'm sure but it will produce a line fit for a speed increase above the current 75 mph.

They did the up main through the up platform in January 1989 and even had new alignment pegs ready to slue the down main through the down platform but never took place. The latest date given to us Relief Signallers/Signallers for the North Wales Coast Resignalling Phase 1 (Rockcliffe Hall to Abergele) is MARCH 2018.

Has it been decided to resurrect the UF at Rhyl?
;
Presumably the down loops were retained at both Rhyl and Abergele to get boat trains past, but that's barely relevant now, while there are up trains fast from the Junction to Chester.

I don't know about future plans, but with regard to retention of loops I can comment. You are correct about retaining the Down Loops for the boat trains (Summer Saturdays mainly, in the '70's).

The Down boat trains used to overtake stoppers at Rhyl and Colwyn Bay; Abergele loops were retained just for access to the platforms. Being Absolute Block worked, tail lamps were observed by the signaller at Rhyl No.1 and by use of the tail-lamp telephone at Colwyn Bay as instructed in the Sectional Appendix. Abergele never had a tail-lamp telephone and, with the signalbox being halfway down the loops, it would be difficult to give Train Out of Section. Therefore trains weren't scheduled to be overtaken at Abergele.

Both Llandudno Junction and Bangor had Down tail-lamp telephones too, as the retained signalboxes were at the No.2 end of the stations.

Interesting stuff, Mark. Pardon my ignorance - I know about tail-lamp cameras, but how does a tail-lamp telephone work?

It's nothing special! It's a telephone connected directly to the controlling signalbox and is sited towards the rear of the platform where the guard's van would stop. It's generally only provided at platforms where trains will stop at, before the train has passed the signalbox. Though it can be used for any train, it's positioned for use with loco and coaching stock in mind. When the train has come to a stand the guard rings the signaller and informs him that the train has arrived complete with tail lamp. The signaller can then give Train Out of Section without the need to observe the tail lamp.

Regards,

Mark

There appears to be a fairly long up loop going in at Mostyn.

Bi-directional to replace Holywell Junction, and retain access to the docks although there is no traffic.

All the boxes will go between Rockcliffe Hall inc and Abergele inc (except Mostyn of course, already closed) in MARCH 2018

All resignalling work carried out (Phase 1) along the coast is progressing well with numerous bases put down for new signals and location cabinets.
