I see you observed one train I also observed, just a little earlier than you, DanTrainMan185! Wonder if you can tell which one it was in the list below.
The thing about a whole day's diagram being posted on Headcodes.info raises a fine point. I was, when transferring my observations from my phone to my notebook during Tuesday's commute, considering adding workings that should have been obvious a train had been. For example, the 0709 Hereford to Birmingham New Street, in theory there's only one service that should have come off, but as the thread title says "Trains you've seen working" not "Trains you've seen working and what they should have been doing". If that makes sense!
Anyway, this is the last of the work to do following Monday's trip now, so let's get it done:

Phew, that took bleedin' ages to type up! It also took up 5 sides of paper in my notebook!
hock: That'll teach me to make notes on what I see!
EDIT: Numbers and services in blue are what I travelled on.
150227, 150235 and 150253 are the ones I want according to my ST Publications book, which should be co-ordinated with my NREA book so I'm definitely after the gen. Knowing my luck, they'll be on Blaenau Ffestiniog, Bidston and HoW services now
