The Department for Transport is in discussion with train operating companies to define the requirements to deliver the additional capacity as set out in the Rolling Stock Plan. It is the responsibility of the operators to ensure that the vehicles are competitively procured and to identify the delivery dates with manufacturers to match the high level output specification funding period.
There have already been 423 additional vehicles ordered, the first of which will commence entry into service later this year. The department has set out in the Rolling Stock Plan that 1,300 additional vehicles will be delivered by 2014.
The Department for Transport recently published High Level Output Specification (HLOS) plan update July 2008, which described the process for implementing the Rolling Stock Plan. This stated that it would announce a number of vehicles different from that shown in the plan only if and when it contracted with a train operating company for a different number.
