I found that the Initial Industry Plan (published last September)
http://www.networkrail.co.uk/IIP.aspx provided some interesting context around the key objectives. To quote from the executive summary:
The Secretary of State for Transport has stated that rail should be at the forefront of
the Government^s transport strategy ^ contributing to the Coalition^s twin goals of
economic growth and carbon reduction. However he has also made it clear that the
current cost of the railway is unsustainable as highlighted by Sir Roy McNulty^s Rail
Value for Money study.
....
A more affordable railway provides government with the opportunity to consider the
choices ^ and the appropriate balance ^ between fares, investment and subsidy in
specifying the outputs and funding for the railway.
Others have questioned the definitions and criteria for affordability and value for money. The industry appears to be suggesting that affordability can be improved without adversely affecting customer facing outputs, so the organisations must be looking at ways to reduce the unit costs of undertaking their core business. If this is the case, the good news is that the business cases for service enhancements are easier to prove, the cost denominator in the equation being lower for the same level of benefit. It is therefore important that options for the new franchise are appraised whilst taking into account the projected cost efficiencies which the industry appears committed to deliver.
"Appropriate" capacity is another interesting one. Does appropriate mean everyone getting a seat in the peak, or an acceptance that there will be large numbers of passengers standing for journeys of half an hour or more? Is an appropriate level of standing different in the London area from the Bristol area? It will be interesting to see if the
DfT» bites the bullet and defines crowding standards in the franchise specification and/or
HLOS▸ , and what the cost will be of providing the capacity which they deem "appropriate". Capacity which is only going to be used in the peak must surely have a high net cost compared with that which is earning money all day.
Sorry, just rambling a bit there...
