Ms Deirdre Hanlon:

I will write to the clerk and let them know whether that is our responsibility or that of someone else.

There is a commitment in the programme for Government that the costings of proposals for the extension of the western rail corridor northwards from the existing part of the project that was opened in 2010 would be examined. The programme for Government also makes a commitment that in the meantime, there would be no development which would preclude its bringing into service for rail purposes in the future.
