Well I was just looking at a possible trip to Nottingham earlier today, splitting at Birmingham New Street, then at Derby as well, but failed to come up with a figure that suited me. However using this, I have found a split that works well for me and I now may be making a trip to Nottingham tomorrow as a result. Hadn't considered splitting at Long Eaton, but that works well and it does at the times I want too
Glad I bumped into this thread now, shall be bookmarking splitticketing.com for future reference as it saves a fair bit of hassle trying to work out potential splits.
As for TCBC, that was ridiculous for me. Hereford to Manchester Piccadilly split, the most sensible one there I'm aware of is Hereford to Shrewsbury and Shrewsbury to Manchester, since the day return was rudely taken away from us for journeys from Hereford ages ago. However, no, TCBC had other ideas. Hereford to Droitwich, Droitwich to Rugeley, Rugeley to Norton Bridge (!), Norton Bridge to Stoke and finally Stoke to Manchester! Not that it all came out that much cheaper anyway!
