Advance booked train fares with reserved seats can be quite cheap, use a route planning service as these can offer some quite unconventional changes or longish waits at change stations to get a cheap rate. Also plan the journey as two separate trips rather than a return ticket. It all helps.

When I was without a car I got down to Cornwall and back for under £100. If I'd been prepared to freeze my butt off at Westbury for 5 hours I could have halved it.
