Go talk to rail capacity ‘experts’

with one comment

Professor Dieter Helm, author of a readable thoughtpiece about HS2 and high speed rail, has been admonished by NCHSR lecturer Mr Gareth Dennis, and advised by the ‘official photographer’ for the High Speed Rail Industry Leaders Group to ‘talk to rail capacity experts’.

twitter, @Dieter_Helm, 'Regulation Network - HS2: a conclusion in search of a rationale' (and selected replies)

But which ‘experts’?

The former HS2 chairman David Higgins?

On 17 November 2014, HS2 Ltd chairman David Higgins told the House of Commons transport committee that 'a railway line where trains travel at 220 miles an hour as opposed to 120 miles an hour clearly has nearly twice the capacity because you can have twice as many trains on it. Once we started talking about capacity, then people started to get it.'

The current chairman Allan Cook?

HS2 Ltd, Cook stocktake report, 'Each intercity train removed releases capacity for 11 new fast commuter or freight trains,
by reducing the disparity in speed between different services. The most efficient use of capacity is where all trains operate at the same speed – as is the case on HS1 and traffic on a managed motorway.'

Mr Gareth Dennis?

The benefits of HS2 could be transformational for Retford, according to the 'Permanent Rail Engineering' (Gareth Dennis) twitter

Or Jim Steer?

  1. From observation, and working with & around railways for around 50 years, the Euston issues would be best resolved by separating the ‘mess’ of the local (DC) services, and inner suburban commuter services using a new set of through platforms which connected through to Waterloo/Charing Cross – releasing around 6 platforms at Euston, and handling the commuting passenger flows through a new arrangement of inbound/outbound passenger facilities directly connecting to Euston Square, Euston, and Warren Street stations, with the latter also available as a contingency measure allowing Euston (Victoria Line) to close, or operate entry/exit only when overcrowding delays trains or creates a safety problem.

    The impact of this improved efficiency also moves to release platforms (and a prime central London site) at Charing Cross, and possibly Waterloo, plus reduce the conflicting train paths (and boost capacity) at these termini as well.

    DC services (TfL- using high capacity ‘metro’ stock) could replace current trains on the Deptford Loop, and for local stations (ie Queenstown Road) to Wimbledon via Wandsworth Town and East Putney where a 6 track viaduct (with only 4 used by SWR services) and paths vacated at Parsons Green and Earls Court would accommodate the Overground services, and provide added, alternative capacity on the Putney-Clapham section, busy in both directions at peak times
