I have received a reply from UKTV Drama re broadcast of Onedin Line:
Unfortunately the rest of the series of The Onedin Line was pulled from
the schedule in October due to contractual reasons. We are pleased to
advise you that we will be showing episodes 4 & 5 on the 29th and 30th
December at 12.00 and 18.00. The rest of the series will be on from the
10 January at 12.00 and 18.00
I asked about the later series being broadcast but this wasn't referred
to in the reply.
