HS2 and Heathrow, part 3

leave a comment »

Greengauge 21‘s February 2010 report The Heathrow Opportunity stated that “There is clear evidence that what is needed is for high-speed rail services to operate directly to (Heathrow) airport“. It contained a diagram showing Heathrow lying north of the Great Western Main Line, with a station at the airport itself, linked to HS2 by both north-facing and London-facing connections, as well as south-facing connections to the Brighton and Portsmouth lines.

But on any one day, the number of people travelling to airports is very small, as a proportion of all transport movements. So building high speed rail into them, or stopping high speed trains to serve them, is unlikely to make environmental or economic sense. Even stopping conventional speed trains to serve them doesn’t necessarily make sense, according to the Association of Train Operating Companies‘ Response to the Department for Transport HS2 consultation:

ATOC notes that the proposed Crossrail Interchange station at Old Oak Common would provide links into the Central London business district, the City and to Heathrow. However, it believes the longer-term business case for all HS2 and most Great Western trains to call at this station needs to be examined carefully with consideration given to the impact on journey times and any benefit associated with the interchange opportunities created. The proposed strategy would undermine the journey time benefits of HS2 and lead to an increase in journey times on the Great Western from London to Reading, Bristol, South Wales and the South West if stops on all Great Western trains were introduced. In the future, following development of a Heathrow spur, some of the advantages of Old Oak Common as an HS2 interchange station for high speed services would naturally disappear and an overall balance therefore needs to be struck between interchange benefits, journey time disbenefits and the timing of any eventual direct link to Heathrow.

Similar sentiments were also expressed in October 2010’s High Speed Lines: ATOC’s view:

“ATOC is not convinced that a Crossrail Interchange station at Old Oak Common and for all HS trains to call, is the right solution to serve Heathrow as it will undermine the journey time benefits of HS2.”
