I think
FGW▸ should only run as far as Southampton, with a connecting service operated by Southern running to Portsmouth/Brighton, as these destinations aren't really "western".
Southampton, however, being the major interchange station on the south coast ( i.e for Bournemouth/Poole/Eastleigh/Portsmouth/Brighton etc. ) should then benefit with a half hourly service to Westbury. One service per hour then continuing to
BRI» /
CDF» and the other service continuing to
SWI» /
GCR» . This then provides Melksham with a train service too.
If all PHB - CDF services were to become Southampton - CDF services, there would then be the units and crew to provide this service, as this should free at least 2 units up, and these 2 units could then become 2 car 158's instead of the current 3 car 158's, therefore providing 3 units for the GCR/SWI - Southampton trips, as well as the one unit currently operating the daily service that currently exists. ( 153 I think ).
The only problem I see with this is what to do with Fratton FGW crew. Sorry guys, but your relocating to Southampton.
Its still early, and Im not fully generated yet, so please ridicule this scenario.
Ok, here's how I see it.
Cutting back Portsmouth-Cardiff and Brighton services would release three 3-coach Class 158 units, as the proposed Southampton-Cardiff services would require six 3-coach Class 158 units.
Because of the need to viably path through the various sections of route, including the single-track Melksham line and the Chippenham-Swindon main line, the proposed hourly Southampton-Swindon services would require 5 units.
This could be done as follows:
Split two of the spare 3-coach Class 158 units into three 2-coach Class 158 units.
Swap the remaining spare 3-coach Class 158 unit with an existing FGW 2-coach Class 158 unit diagram. This would have the added advantage of providing more seating capacity on said diagram.
Insert calls at Dean and Mottisfont & Dunbridge in the proposed hourly Southampton-Swindon services. Divert the
SWT▸ Romsey-Southampton-Salisbury services to Totton instead, just as they used to be. As well as making Denis and the SHRUG folks very happy indeed, this would free up a further 2-coach Class 158 unit, which could then be transferred to FGW.
You now have your 5 Southampton-Swindon units, all of which are 2-coach Class 158's.
This is where the problems start:

The problem with this is the turnaround time at Southampton of the services from/to Cardiff ^ 6 minutes is a complete no-no for a regional service.
In general terms, the merest hint of a tight turnaround time will see a timetable proposal rejected these days, especially if the powers that be dont like the overall idea anyway. Personally, I've given up even bothering to submit any to them. Banging ones head against a brick wall loses its appeal after a while.
Therefore, its time to look at...
PLAN B
Cardiff Central xx30 ^ Newport xx44 ^ Filton Abbey Wood xx09 ^ Bristol Temple Meads arr xx18, dep xx22 ^ Bath Spa xx36 ^ Bradford-on-Avon xx47 ^ Trowbridge xx53 ^ Westbury arr xx00, dep xx01 ^ Warminster xx08 ^ Salisbury xx32 ^ Romsey xx50 ^ Southampton Central xx04. Then forms:
Southampton Central xx27 ^ Romsey xx 38 ^ Mottisfont & Dunbridge xx43 ^ Dean xx49 ^ Salisbury xx04 ^ Warminster xx25 ^ Dilton Marsh xx29 ^ Westbury xx33 ^ Trowbridge xx39 ^ Melksham xx50 ^ Chippenham xx01 ^ Swindon xx18.
Swindon xx45 ^ Chippenham xx01 ^ Melksham xx11 ^ Trowbridge xx20 ^ Westbury arr xx27, dep xx40 ^ Dilton Marsh xx42 ^ Warminster xx49 ^ Salisbury xx12 ^ Dean xx24 ^ Mottisfont & Dunbridge xx30 ^ Romsey xx35 ^ Southampton Central xx46. Then forms:
Southampton Central xx10 ^ Romsey xx21 ^ Salisbury xx41 ^ Warminster xx01 ^ Westbury arr xx07, dep xx08 ^ Trowbridge xx14 ^ Bradford-onAvon xx20 ^ Bath Spa xx35 ^ Bristol Temple Meads arr xx47, dep xx54 ^ Filton Abbey Wood xx01 ^ Newport xx25 ^ Cardiff Central xx43.
Plan B solves the Southampton turnaround problem, but would result in some Southampton-Cardiff services being formed of 2-coach Class 158 units. Recent history teaches us that this would not be a wise move.
Time for...
PLAN C
This is more radical, as it involves removing the calls at Romsey and Warminster in the Southampton-Cardiff services, in order to improve journey times, in turn giving a more robust turnaround time at Southampton Central.
Cardiff Central xx30 ^ Newport xx44 ^ Filton Abbey Wood xx09 ^ Bristol Temple Meads arr xx18, dep xx22 ^ Bath Spa xx36 ^ Bradford-on-Avon xx47 ^ Trowbridge xx53 ^ Westbury arr xx00, dep xx01 ^ Salisbury xx30 ^ Southampton Central xx59. Then forms:
Southampton Central xx15 ^ Salisbury xx43 ^ Westbury arr xx07, dep xx08 ^ Trowbridge xx14 ^ Bradford-onAvon xx20 ^ Bath Spa xx35 ^ Bristol Temple Meads arr xx47, dep xx54 ^ Filton Abbey Wood xx01 ^ Newport xx25 ^ Cardiff Central xx43.
Swindon xx45 ^ Chippenham xx01 ^ Melksham xx11 ^ Trowbridge xx20 ^ Westbury arr xx27, dep xx40 ^ Dilton Marsh xx42 ^ Warminster xx49 ^ Salisbury xx12 ^ Dean xx24 ^ Mottisfont & Dunbridge xx30 ^ Romsey xx35 ^ Southampton Central xx46. Then forms:
Southampton Central xx27 ^ Romsey xx 38 ^ Mottisfont & Dunbridge xx43 ^ Dean xx49 ^ Salisbury xx04 ^ Warminster xx25 ^ Dilton Marsh xx29 ^ Westbury xx33 ^ Trowbridge xx39 ^ Melksham xx50 ^ Chippenham xx01 ^ Swindon xx18.
Though not impossible, 16 minutes is still rather short to turnaround a regional service every hour. Also, Romsey and Warminster passengers are likely to cry foul at being disenfranchised, and the resulting negative publicity would probably not be worth the hassle. Same applies with any other "lamposts" one might wish to take out instead.
A further option would be to do a total network recast, and see where your chips fall then. However, I see no great appetite existing for this, especially if the ^Emerging Strategy^ section of the
GW▸ RUS▸ is anything to go by.
However, lets say you get round all this somehow. You then have the following further obstacles to overcome:
- The SW RUS was pretty clear in its opposition to further terminating services at Southampton Central. I can see their point. It would not be outlandish to foresee several terminating trains causing congestion chaos, and that aint no way to run a railway in such a location.
- The reason that the FGW Brighton services continue to exist is because the financial and economic case for their removal simply doesnt stack up. They arrive and depart in Brighton at high peak, thus maximising
ORCATS▸ revenue and providing extra capacity along the Brighton-Havant ^ Southampton corridor during these periods.
It is also worth looking at it from my perspective as a passenger.
You will mainly find me travelling on Portsmouth-Cardiff services between Cosham-Westbury or Cosham-Bristol, depending on where I am ultimately heading. At the moment I can do these journeys direct, with a reasonable chance of a good choice of seats. In short, I can start my day in a relaxed, pleasant and convenient manner.
Why would I, and my fellow passengers from the Portsmouth/Fareham end want to swap this for changing and joining the Southampton travelling massive in an enlarged scrum for seats? Indeed, why should we have to, when our end of the journey generates a perfectly good level of revenue, justifying our inclusion in the service?
More generally though, I dont agree with those who advocate radical change to Brighton/Portsmouth-Cardiff corridor services. The chaos of December 2006 and its aftermath excepted, they are by and large a success story, which points to evolution, rather than revolution, being the way forward.
What actually needs to be done is to introduce a proper Westbury-Swindon service asap, and take an incremental approach to introducing additional capacity/services on the Portsmouth-Cardiff corridor as and when they are required.
Lets fix what is broken, rather than what actually works.
