Ryanair didn't get where it is by offering more services than it feels it needs to. However, where it has been seen to fall down is in not providing sufficient and timely information to customers to make alternative arrangements. Perhaps they should at least offer one point of contact at each of its airports to provide information on their flights during the hours that passengers may be reasonably expected to require that information.
As for providing trains for delayed flights, I can understand the point being made in relation to Stansted, but it's really an issue for the BAA and WAGN trains to sort out.
