Transport Direct can be your friend....
Indeed ... it came up with same services I used all the way, but added in an extra one (9 mins walk, 4 mins on the bus, 5 mins walk) in place of my walk across Burton. I *had* looked at my general directions and distance in Burton-on-Trent to give me an idea of distance and direction when I got off the train.
Alas, Transport Direct helps, but doesn't reschedule the busses so they don't run in pairs, nor make one of them integrate at the station.
