Adelaide public transport

I'm heading into Adelaide from Craigmore tomorrow.
What's the quickest way to get into the city via public transport at the moment, given the works happening on the railway?
I can:
A) Catch train to Mawson Lakes and then bus in city
or is it easier to:
B) Catch the 228, or whatever the route is called now, from Elizabeth Downs through to Adelaide?
Anyone know?
