This follows the government's decision to provide a further £3.1m to cover cost increases during construction of Stage 2 of the line. This increases the government's contribution from £6.5m to £9.6m.
The additional money will also allow Nottinghamshire CC to let the contract for the construction of the Kirkby in Ashfield station which the council deferred last year.
Speaking about the decision, Mr Norris said:
'This demonstrates the government's commitment to public transport and its wish to see the Robin Hood Line a success.'
Robin Hood Line train services operate betweeen Nottingham and Mansfield Woodhouse, a distance of almost 19 miles.
The service was inaugurated by the transport secretary George Young, on 10 November 1995 and regular services commenced on 20 November.
