The GW▸ are not removing line side signals ..... yet
The Western Route Summary Route Plan says:
Western key output 8: all trains ETCS▸ fitted/Lineside Signals removed ^ by December 2025
It also says this:
The introduction of ETCS is expected to reduce the equipment requiring trackside attendance for routine maintenance. The full benefits of this will not be realised until the signals are removed in 2026. In the short term, the dual fitment of ETCS alongside ATP▸ will increase the maintenance burden.
Considering the age of the equipment most of it is performing well, with many equipment types (particularly the mechanical signalling infrastructure) still in service long beyond their envisaged service life.
Exactly .......... this will put the nail in the coffin of class 43's (aka 253 & 254) so the demise of the
HST▸ 's will be in just over 10 years which will make them 50 years old which all said and done is a life cycle for railway rolling stock far longer than any other public transport vehicle
I am not convinced that all these dates will be kept, certainly for the outer reaches of the GW network. Network Rail's 'Strategic Business Plan' (which is its response to the Government's
HLOS▸ ) is a work in progress and its final version will be published in March 2014. Even in the current version (from which the above quotes were taken) there are some inconsistencies and assumptions which are made. One of these is on page 58 of the Western Route Plan referring to ETCS
Each framework contractor is required to demonstrate their system functionality at Hertford National Integration Facility (HNIF) in 2013. ETCS programme has access to the facility between March and December 2013 and an intense trial period for each contractor to demonstrate that their system works.
As I understand it, this programme is running late and these comparative studies have not yet been completed so the appointment of a main contractor, planned for January 2014, looks unlikely. This has to increase the risk that the first implementation of ETCS on the Western (for Crossrail to Heathrow) in December 2016 (in the text and diagram on page 58) will be delayed.
Another statement which I don't entirely understand is on page 74
The main lines from Paddington to Bristol are fully fitted with ATP. There is intermittent fitment on the Berks and Hants line. ATP will be replaced by ETCS but will be maintained until fitted trains are all withdrawn (2020/2021), subject to the challenges of obsolescence support.
This implies, at least to me, that all HSTs and Class 180s will be withdrawn by that date - or at least will not be able to operate via Bristol. This seems odd as (a) not enough
IEPs▸ /Super Express Trains have been ordered to operate the service to Plymouth and Penzance and (b)
AIUI▸ there are questions as to whether the bi-mode versions can cope with the Devon banks on a regular basis.
Whilst I agree that the end-of-life of the HSTs cannot be put off for ever, it would be a brave man who did not hedge his bets that all the planned improvements and changes will happen as planned now. I would think that at least a 'strategic reserve' of overhauled and updated HSTs will still be running in 12 to 15 years time - and their leasing costs are much lower than those of the IEP will be^!
Edited to try to get the quoting correct...
