For the best info and history on the BA including a timetable spreadsheet visit:
J Liennard BA siteTo my knowledge the BA/RFF/SNCF have closed the section from Valencay to Lucy le Male because of PW problems. There is a replacement bus or taxi.
The whole BA is suffering from infrastructure issues and lack of money and there are speed restrictions in place on the whole line.
There is a lot of info here:
Passion MetriqueFor me it has never been the same since they bought the new railcars. The old Verney's (and De Dions) and the line had character.
...And there was a grumpy old (non-railway enthusiast) git living in the station at Pruniers when I last visited where I want to live....
Don't forget to visit the real BA though....
Train Bas Berry
Lucy le Male - Argy
If you travelling via Caen or Le Havre you'll be passing near Le Tramway de Petit Boisney.
That has not been closed by the RFF but they are waiting for new 'diesel' electric traction....
