Title: Problems with lineside equipment at Worcester Post by: dzug on February 11, 2013, 08:53:33 These seem to be occurring on a virtually daily basis at the moment causing cancellations and amendments (which normally means curtailment at Oxford...).
Is there any 'story' behind it? Title: Re: Problems with lineside equipment at Worcester Post by: Worcester_Passenger on February 11, 2013, 09:19:09 I was about to ask the same thing.
Where it happens seems to move up and down the line. Once upon a time things didn't really go wrong with our line's signalling - partly because there wasn't much that could go wrong.

Title: Re: Problems with lineside equipment at Worcester Post by: martvw on February 11, 2013, 19:49:08 The trouble with the line side equipment in the worcester area is that most of it is held together with string, very old string !!
Title: Re: Problems with lineside equipment at Worcester Post by: pbc2520 on February 11, 2013, 20:32:23 I expect thetrout is referring to this little incident...
http://www.bbc.co.uk/news/uk-england-hereford-worcester-21410006 (http://www.bbc.co.uk/news/uk-england-hereford-worcester-21410006) I always wondered why trains from Malvern to Worcester would come to a stop before Henwick more often than not. Perhaps this goes some way to explaining it. New locks please. Title: Re: Problems with lineside equipment at Worcester Post by: Worcester_Passenger on February 12, 2013, 04:43:36 Alas, the incident on Monday (Feb 11) wasn't down to the Henwick signaller being stuck in the outside toilet (that was last Thursday, Feb 7).
And it caused much more chaos. One of the London trains was nearly two hours late into Paddington. Meanwhile, the reason that trains are often stopped on the approach to Henwick is the matter of the two single lines through Foregate St station - sometimes there's a train coming the other way that's occupying the platform that your train wants. And sometimes it's simply the crossovers : a Malvern to Shrub Hill train has to cross over the path of a Droitwich - Malvern one. Title: Re: Problems with lineside equipment at Worcester Post by: martvw on February 12, 2013, 18:16:06 The sooner the track layout and signals in the Worcester area are brought into this century the better, with perhaps a new double junction or a crossover at Rainbow Hill, so both platforms can be used at Worcester Foregate Street Station by London bound trains, also new double track round the curve into Shrub Hill Station, thus no more bottle neck?

The layout was fine until it was rationalised in the 1970s Title: Re: Problems with lineside equipment at Worcester Post by: Andy W on February 12, 2013, 19:19:30 You might find this interesting regarding the Worcester rationalisation.
http://www.miac.org.uk/1973signals.htm Title: Re: Problems with lineside equipment at Worcester Post by: stebbo on February 12, 2013, 20:16:34 The signalling and track layout at Worcester is clapped out and needs urgent updating. As I understand it, the age of the signalling is one reason - apart from money - preventing a redoubling of the Cotswold line up to Norton Junction.
The layout at Henwick and through Foregate Street is madness. Title: Re: Problems with lineside equipment at Worcester Post by: SandTEngineer on February 16, 2013, 14:51:38 Yes....... but you have to remember that the railway in the late 1960s early 1970s was in very rapid decline. BR had to save as much money as possible (unlike a certain railway infrastructure company that exists now) and quite a few of these 'track rationalisation' schemes could easily deal with the train service pattern that existed at that time.
Interestingly I was watching this website for an hour today (virtual gricing I know ::) ) http://www.opentraintimes.com/maps/signalling/WJ/1 It looked as though the Fast lines south of Watford Junction were blocked for some reason but despite a fairly flexible track layout trains were begining to stack up and be held at red signals for a considerable time. So, modern track layouts are no good if you don't use them :P Title: Re: Problems with lineside equipment at Worcester Post by: stebbo on February 22, 2013, 16:53:17 Yes I understand that, but the Worcester layout is utterly nuts. I can understand singling the curve to Shrub Hill, but who dreamt up the layout through Foregate Street?
And the situation at Norton Junction where a London bound train can take the junction at, I believe, 70 mph but Worcester bound trains have to slow right down...... Title: Re: Problems with lineside equipment at Worcester Post by: SandTEngineer on February 23, 2013, 17:23:45 Yes I understand that, but the Worcester layout is utterly nuts.

And the situation at Norton Junction where a London bound train can take the junction at, I believe, 70 mph but Worcester bound trains have to slow right down...... Well. Looking back, the layout through Foregate Street is quite sensible for the train service pattern then running. They saved on the pointwork (and signalbox) at the former Rainbow Hill Junction and only had to install a new facing crossover at Henwick (the trailing one already being in existence). At Norton Junction the existing trailing crossover was used for egress from the Oxford line and this limits the speed to 20mph in that direction. Quite sensible and cost effective ecomomies (at the time). Title: Re: Problems with lineside equipment at Worcester Post by: martvw on February 23, 2013, 19:34:21 Lets hope that some time soon the track work is improved in the hole of the Worcester area.

How big it this hole that is so large it covers the Worcester Area Title: Re: Problems with lineside equipment at Worcester Post by: SandTEngineer on February 23, 2013, 20:08:47 Referring to the 1973 timetable. 4 Worcester bound trains (2 of which terminated) and 3 Birmingham bound trains per day utilsed the 'Birmingham' line platform at Foregate Street (in the peak periods only) and 14 Down trains and 14 Up trains used the 'Shrub Hill' platform at Foregate Street. So the layout was suited to the train sevice pattern. No trains called at Foregate Street on Sunday :o
Title: Re: Problems with lineside equipment at Worcester Post by: SandTEngineer on February 23, 2013, 20:11:25 ........and thank your lucky stars that the Shrub Hill to Norton Junction rationalisation never got implemented as this would have meant two parallel single lines, one between Shrub Hill and Evesham and one between Shrub Hill and Abbotswood Junction ;)

No trains called at Foregate Street on Sunday :o So the track layout is determined by the timetable?Surely you have a track layout that allows the best flexibility within a sensible budget. Exactly how many other two platform stations are there in the country that are restricted to two single line operations? II you may know. I didn't think Worcester was that bad.

Actually, they did better than that, because they saved the signalbox at Rainbow Hill Junction and the one at the north end of Shrub Hill (Worcester Shrub Hill Junction box). A signalling scheme which took out two boxes and transferred some of the work to the adjoining three is a pretty good scheme for 1973. A brand-new power box would have been nicer, but there wouldn't have been the money for capital investment on that scale.

Track and signalling layouts are always engineered to the proposed service. It is extremely costly to put in additional ironwork that may be never used, or used once in a blue moon! I know this stinks of short-termism but 'hey ho' thats the modern railway for you :P Title: Re: Problems with lineside equipment at Worcester Post by: Andy W on February 27, 2013, 08:12:00 In response to the earlier post.

I know this stinks of short-termism but 'hey ho' thats the modern railway for you :P But they didn't put track in -they removed track. The concept that it would never be used is also wrong - it would have been used in exactly the same manner that it had been used previously. A whole lot of cost could have been saved if they'd left well alone. When does short-termism become vandalism? ??? Title: Re: Problems with lineside equipment at Worcester Post by: Worcester_Passenger on February 27, 2013, 09:14:02 A whole lot of cost could have been saved if they'd left well alone. You have to balance that against the savings in operating two whole signalboxes, probably on a 24-hour basis (given they're junctions, it wouldn't be easy to switch them out), for forty years.I think the railway made the right call back in 1973. Title: Re: Problems with lineside equipment at Worcester Post by: John R on February 27, 2013, 21:08:24 So, assuming a 24/7 box needs six staff to cover it, then in today's money that's at least 250k pa just for staffing costs, let alone maintenance of the box, point work etc. I can see why it might have been considered attractive.

You are saying you require 2 fewer signal boxes to run two seperate single lines with associated single line operating equipment than a double line. Looking at the diagram - if it was left as a double line operation signals A,F,G and H would not have been required. The only limitation is that Birmingham - Hereford trains would miss out Shrub Hill. Which 2 signal boxes were made redundant by this exercise?

Hi WP we are never going to agree on this, but out of interest which two whole signal boxes were no longer operated? Exactly what did each signal box control?Title: Re: Problems with lineside equipment at Worcester Post by: Nottage_Halt on February 28, 2013, 21:18:49 A whole lot of cost could have been saved if they'd left well alone.

The only limitation is that Birmingham - Hereford trains would miss out Shrub Hill. Which 2 signal boxes were made redundant by this exercise? In fact, three 'boxes were closed as a result of the 1973 Worcester rationalisation. Wylds Lane Junction, which controlled the entrance/exit to the goods lines at the London end of the layout (close to the Metal Box siding, somewhere near where North Sidings Ground Frame now exists. A little to the west, is the still standing Shrub Hill Station Box. Heading west from the passenger station at Shrub Hill, there was Shrub Hill Junction 'box, in the "V" of the divergence between the Hereford and Birmingham routes. The third closed 'box, was Rainbow Hill Junction, situated in the "V" between the lines from Shrub Hill and Tunnel Junction, at the western end of the triangular layout. Earlier, (early/mid 1960's?) Foregate Street Station lost its signalbox, which had been situated on a bridge joining both platforms, above the tracks. Even earlier than this last 'box at Foregate Street, was it's predecessor, which has lately become a caf^, at the country end of platform 1. And there were at various times other signalboxes at Worcester too, on the goods lines.

Title: Re: Problems with lineside equipment at Worcester Post by: Andy W on March 01, 2013, 07:49:18 Hi Guys thanks for the input - I'm not explaining myself.
Part of the rationalisation meant that Foregate Street was reconfigured from a station on a double line to two single line stations. WP made the following statement A whole lot of cost could have been saved if they'd left well alone. You have to balance that against the savings in operating two whole signalboxes, probably on a 24-hour basis (given they're junctions, it wouldn't be easy to switch them out), for forty years.I think the railway made the right call back in 1973. I am not disputing other work that removed redundant track work - it is the singling of WOS to WOF and WOF to Rainbow Hill that I don't understand. By implementing two sections of single line working, this must surely make operations more complex. Additional signals and equimpent are required that would not necessarily be needed if double track remained.

Part of the rationalisation meant that Foregate Street was reconfigured from a station on a double line to two single line stations. Now what I don't understand is how reconfiguring the station saves 2 signal boxes.

By implementing two sections of single line working, this must surely make operations more complex. Additional signals and equimpent are required that would not necessarily be needed if double track remained. The fact that Foregate Street Station ended-up with two bi-directional platforms was a by-product of the rationalisation, rather than the main purpose of those works back in 1973. By, moving the junction between the Hereford and the Tunnel Junction lines out to Henwick, Rainbow Hill Junction box could be closed. Putting control of the junction between the Droitwich and Hereford lines (west of SH station) onto Shrub Hill Station box, allowed the elimination of Shrub Hill Junction box. This left two single lines eastwards from Henwick - one to Shrub Hill, the other to Tunnel Junction. The additional signalling amounted to not all that much - acceptance lever & track circuit working over the newly created bi-directional lines, some new signals and re-control of others and some switches. The new stuff would have been far less than what was recovered during the works. As Henwick almost certainly had to remain in-situ to control the Level Crossing, the rationalisation design seems to have been a rather good one in the circumstances (no money) and diminished traffic of its time. Title: Re: Problems with lineside equipment at Worcester Post by: SandTEngineer on March 02, 2013, 13:37:53 ......and saved the renewal cost and ongoing maintenance cost of a lot of S&C. For example here is the old layout at Shrub Hill Junction:
