Mr. Hugh Creegan:

I understand the attractiveness of such a service. It is down to the money investment that is required.

I have wondered about vending machines myself. I think the issue is that we would probably have to take seats out to make space for the vending machine or take the toilet out of the carriage, and neither of those are attractive propositions. All I can say is that we will keep the matter under review. It may be that something can be done in the future, but for now the money is literally not there to support that service.
