Indeed, I had a thread about Hartford a few weeks back. I hadn't realised it once had through services to both Euston and Paddington back in the day.
It does irk me slightly that it ought to be possible to go North from there to Warrington/Preston/Blackpool/Manchester/Scotland, but the only train service it gets is the BHM-LIV one.
I spoke with LM about Hartford services once, they had put in a proposal to run some of their EUS-CRE services to call at HTF, but I believe the ORR put a stop to it. Shame really.
Then again, whilst Hartford is incredibly useful for me to visit my family, you can't get away from the fact that the place is a tiny little village in rural Cheshire and has two rail stations, both with hourly train services.
