69 from Saggart village, 50 and 65b from Citywest, luas soon
Combined the 50 and 65b run about every 20 minutes, but they divert through Killinarden which makes the journey longer than it should be...
Circle line buses http://www.circlelinebus.com/ run a private service for people working in Citywest and living in town.
Also Dualway buses go through Citywest but not sure if they head into town.
