There's a bus service that runs every 10 minutes in both directions and with stops along Albert Road (near Porters, Phoenix, Leopold) and in Eastney (Sir Loin of Beef), with a northern swing towards Milton, passing the proposed site of the new micro on Eastney Road.
This may not be everyone's cup of tea, but for those who want to expand their horizons a little, I think a Plus Bus ticket may have to be a consideration, when buying train tickets.
