The Department for Transport does not keep the detailed information required. However, we know that in May 1995, the number of vehicles on lease was 10,401 and, as of today, the number on lease on the rail network is around 11,150, an increase of approximately 7.2 per cent. It should also be noted that a further 1,300 vehicles will be delivered as part of high level output specification (HLOS), of which 423 have already been ordered.
