The Department for Transport does not have records of the number of officials who have worked on the Channel Tunnel Rail Link project as far back as 1997. However we do have figures for the number of full-time equivalents from 2002 as follows:
2002 to mid-2005 inclusive: Five
Mid-2005 to 2007: Three
2008 to date: Two.
These figures relate to the delivery phase of the Channel Tunnel Rail Link.
