I will be moving back to the UK later this summer and would like to
locate to the Midlands, but of course work will want me to be working
in London (at least for the majority of the week).

As it's been a while that I've been away (over a decade) I went online
to try and get rail schedule/pricing etc... However I'm not sure if
I'm reading it correctly but it looks like the daily return rate is in
the range of 40-80 per day. Is this correct? Have the rates gone up
this much?

Any suggestions on weblinks etc? I'm all googled out
