A little bit of research has shown that the goods yard at Holme (where I partake in a quiz at the Admiral Wells pub every Tuesday evening within sight of the gate box) closed, so it is claimed, to all traffic on 31st October 1970. The freight services to Ramsey ceased in December 1973 (according to several sources including Ely model railway club) although it is claimed elsewhere that it was 1971 according to a photo caption (http://www.disused-stations.org.uk/r/ramsey_north/) which shows a diesel shunter in charge of a train of box vans allegedly at Ramsey North. That same photograph appears on another website that claims closure was in 1972! It would make sense to me that Holme goods yard would have survived, even if only as a refuge, until the Ramsey North traffic ceased. Incidentally the pub, and the former station, now lie 6' below sea level according to local claims. There are some old photographs of the station and it's staff in years gone by that now grace the pub walls.
There are suggestions that the current gate box at Holme (now disused), which is built on top of a relay room (apparently) was built in about 1975.
Whilst I can find no proof there is a suggestion that the station building might have lasted that long although I can say for certain they were still there in 1962 thanks to a wedding photographer in Peterborough who has some railway pictures on line as well.
