It is not possible to run a 2 tph service though. The loops at Chard and Honiton are not positioned correctly to allow it, they'd both have to be moved to the mid points between the double tracked sections. This has been analysed to death before now, I went as far as drawing detailed graphs of distance/time, and it can't be done.
I gather Axe & Broom level crossings are shortly to be closed temporarily for 'upgrading' work. Does this mean that there are plans afoot to widen them to extend the Axminster double track section to go as far as Chard Junction loop? Not heard anything about extensions, but anyway, connecting Axminster and Chard loops gives very little operational benefit. It might provide a perturbation margin, but it still doesn't help increase frequency. Assuming that the obvious increase over an hourly service would be to a half hourly through service, you'd need both a loop exactly half way between Axminster and Yeovil Jn, ie just about at Crewkerne, and you'd also need another loop somewhere west of Whimple (like Cranbrook). Can't see it even in the medium term, even the half hourly Exeter to Axminster stopper is pretty much on the back burner as far as I can see. The GWML▸ RUS▸ reckoned there was no business case yet. (It did make me wonder why it's discussed in there BTW▸ - perhaps because it is Exeter related?) Paul

Tyne Yard - similar set up to Tinsley - masssive investment and hardly ever used. The layout of the hump yard there is still obvious on Google Earth, Multimap etc. Search for 'Low Fell'.. One way of looking at it is how could BR▸ have collectively, and so comprehensively, failed to notice what was happening on the roads? Paul

The only thing that makes me think different is why would SWT▸ want to hire surplus stock when they are cutting back in other areas? Though they do seem to be the third party ROSCO» whenever a TOC▸ needs a unit or two.
There are normally 27 159s diagrammed daily from 30 units. That is pretty much normal DMU▸ utilisation of 90% - so where's the big surplus? If FGW▸ have two all but one will be in use that day. Perhaps they are covering with 450s elsewhere, or for the odd day they have tweaked the maintenance plan. It will be interesting to see what they do on the day. I therefore doubt the units could be released for a long term period, and as for the units hanging around Salisbury depot all day, it isn't the case in the peaks. Like all the other SE commuter TOCs, a lot of stock is free mid day, buit it comes out again late afternoon. As for the 158s running over the third rail all day that's a completely different question AFAICS▸ ... Paul

If i remember hearing somewhere correctly, there will be enough paths on the single line to have an extra HST▸ in each direction per hour. Both HSTs would pass at Axminster, and then pass the SWT▸ services at Chard Junction and Honiton.

The loops at Chard and Honiton are not positioned correctly to allow it, they'd both have to be moved to the mid points between the double tracked sections.

Because it could work over the third rail electrified at Basingstoke and any train which could do that cannot be DOO▸ . Same for the Gatwicks.
Really? Are you saying you can't have DOO anywhere on the third rail network? There's plenty of SN suburban services are DOO, and then there's various bits of the LO network, and FCC▸ are fully DOO on the Brighton Line... Or have I misinterpreted what you are suggesting? Paul

Between Exeter and Yeovil HST▸ 's are often Diverted when Exeter St Davids-Taunton is closed. Due to limited paths some SWT▸ Waterloo-Exeter trains terminate Yeovil and FGW▸ HST's call at stations Yeovil Junc to Exeter hence the HST stop boards.
I think previously most SWT's to Exeter were cancelled beyond Yeovil Jn and replaced by a limited FGW service, before the hourly service became possible, but AIUI▸ we haven't had any weekend diversions since? It will be interesting to see what happens next time. Perhaps they'll run alternate hour FGW and SWT services. Paul

All across the Great Western territory / Fare's Fair / Re: Group Stations and Ticket Barriers

I think you'd only get a ticket issued to Portsmouth Harbour if you buy at Fratton or Portsmouth and Southsea.
Surely though it was fairly predictable that a ticket with 'Portsmouth Stations' on it would be swallowed at the 'town station'? You'd finished one of the possible journeys it allows?
The purpose of grouping stations for fares purposes was historically to reduce the number of pre-printed tickets held in ticket offices, when fares to the destinations were the same. But as every ticket is printed at the time of issue nowadays, it would seem possible to print them to an explicit destination, but that brings up other problems. You'd then get people complaining when they were told they couldn't get out at Southsea because their 'Advance' ticket was to the Harbour...
