Far south west - Train Performance

[whole diary]

[SandTEngineer]

Is it me or are things getting worse.  Here are the Plymouth to London Paddington train performance figures for the last 12 weeks:

I've been noticing at Liskeard the "up" is often 5 minutes or more late by reaching here, fairly early in its journey. This is observations and often doesn't reflect what the CIS^▸ (Customer Information System) is showing.

[IndustryInsider]

Pretty worthless having a 3h 00m headline timing if it's only achieved 7% of the time.

[bobm]

I wonder what the figures are from the South West to Reading?  A lot of delays are incurred with signalling problems that have plagued the stretch from Reading to Paddington.

(Not that the Berks & Hants doesn't have its moments!)

[Adelante_CCT]

Roughly 10 minutes late on average at Reading with around 50% 'on time' margin for those same services.

Quite a few "slippery rails" over the past couple of weeks

Not much better:

Agreed, although there won't be the padding built into the Reading times as there is at a final destination all too often.

[Adelante_CCT]

Roughly 10 minutes late on average at Reading with around 50% 'on time' margin for those same services.

Sorry, I was referring to 'on time' up until 5 minutes late, rather than exactly on time as has been posted by SandT, which shows very grim reading indeed.

[SandTEngineer]

I've carried out a similar exercise for Bristol TM^‡(resolve), Cardiff and Cheltenham and the figures are at least 50% better than those for the Southwest.  Think that GWR^▸ (Great Western Railway)/NR^» (Network Rail - home page) need to do some work here

[SandTEngineer]

Despite the GWR^▸ (Great Western Railway) overall November 2016 performance figures (http://www.firstgreatwestern.info/coffeeshop/index.php?topic=16825.30) the actuals for the far Southwest seem to be getting worse.

[IndustryInsider]

The first time, during your date periods, that a train (only the one mind) has been on time more often than not!

[SandTEngineer]

I've been doing some research into where the delays are occuring and, not supprisingly, its mostly poor regulating between Slough and Paddington.  It would appear that the signalling system 'Automatic Route Setting' (ARS^▸ (Automatic Route Setting)) equipment is not functioning to its optimum and this is resulting in conflicting movements being signalled that it eventually takes up to 15 minutes to settle down again only for the next conflict to trigger it all off again.  If you watch the Paddington map on Open Train Times (http://www.opentraintimes.com/maps/signalling/d3_1) you can see this happen. Quite often you will see Paddington departing trains being signalled down Line 2 when Line 1 is free, resulting in no alternative to Line 3 for inbound services.  Line 3 has some very restrictive signalling controls that were implemented at the time of the Ladbroke Grove accident and quite often trains are held as far out as Old Oak Common waiting for Line 3 to become available when Line 2 could have been available.

Signallers are instructed not to intervene as they are at risk of discipliniary action if they delay other trains by altering the priorities.

So looks like we are stuck with very rarely having an 'on time' arrival at Paddington (and of course, its all likely to get much worse in 18 months time)
