The current website is a disgrace, the new website can handle nearly all of that from the demos I've seen.
It will have much greater level of information on stations, including google streetview integration. There is also completely new journey planner which also has the ability to handle addresses and includes mapping
Fare information for all Dublin commuter journeys is also in the system as is a completely revised display of fares
The station page will automatically include all relevant engineering works, delays and changes which effect services there
There is talk of a innovative multimodal journey planner as well, commercial sensitivities preclude any discussion of that right now but it has Dublin Bus and Luas routes on it as well.
In the meanwhile
