I never heard of a turntable at Accy station...there was certainly at least one where the engine sheds and sidings where toweards Lonsdale Street.
However - it was possible to turn trains round at Accy station by virtue of the fact that it was a triangular station (one of only 6 in the country)...so a train coming from Church to Accy, say, would head down the Manchester Line, reverse over & up on the Manchester-Burnley line, then reverse over & down on the Burnley-Accrington line. Train turned round!
