It's re-announcement time again

However, we do get a date this time.
In terms of the public transport interchange, it's my understanding that in addition to the 205 and 226, which already serve the station, the city terminus of the 206 will move there, which will mean a direct bus route to Douglas. Also, the 221 service to Glanmire, which already goes past the station outbound will stop there in both directions.
It does make sense to terminate buses from West Cork there, not least because it will relieve pressure on Parnell Place bus station, but I haven't heard of any definite plans.
