Railways Chris Grayling To ask the Secretary of State for Transport how many (a) locomotives, (b) multiple units, (c) freight wagons and (d) carriages were in use on the rail network in the most recent period for which figures are available, broken down by (i) train operating company and (ii) class. Mr. Tom Harris Tables giving details of the number of locomotives, multiple units and carriages used by franchised passenger train operators, broken down by train operating company and class has been placed in the Libraries of the House. Not included are vehicles operated by Scotrail (for which the Scottish Executive is responsible) and non-franchised operators such as Network Rail, open access and charter operators. Information on the number of freight vehicles used on the network is not held by the Department. This information is based on latest available data but variations in the figures can be expected due to short term vehicle hiring, introduction of new fleets, withdrawal of older vehicles and cascades.
