From elsewhere ... the question was asked about the shortest section of passenger carrying railway that  has been closed to passengers.   Set me thinking about our area and cutbacks ...

Gunninslake (SR) cut back to new Gunnislake station in 1994
Looe shortened to using just the outer end of what was the old platform in 1968

I read of other stations moves back - from Uckfield to Fort William, from Sudbury to Broad Street (before it close all together) and suspect there are more in the South West ...

Nationally, my winners are Orkmskirk and Kirby, where sections of just a few yards have been closed breaking the old through routes out of what was Liverpool Exchange.

Lincoln St Marks?

Bradford North Curve and lots of others like it?

Ardrossan Winton Pier closed in 1987 in favour of new Ardrossan Harbour Station 200 metres to the east.

Former Balloch Central station closed in 1988 in favour of new Balloch station just across the road less than 100 yards away.

Terminal stations, especially if they were at the end of branch lines, and even more so if a disusued goods yard was close by, were seen as prime development sites if their lines managed to survive Beeching. So, off the top of my head:

Marlow
Henley
Exmouth
Morecambe
St Ives
Newquay?
Bradford Forster Square
Bradford Exchange/ Interchange
Blackpool South
Original up platform at Dorchester South
Lymington Pier

Electrified in the 1960s, Bullock Pier Station was closed from the Central station in 1986. The last Loch Lomond steamer called there five years earlier.

Like Uckfield, Balloch Central station was moved to allow the removal of a level crossing.

Thanks bradshaw - I would quite literally kill for the sign from Bullock Pier Station  ;D

There's another likely reason to move platforms along the line - to steal the old platfoms for something else. The obvious something is a metro, and we've seen that at Twyford and Maidenhead, at least operationally. In both cases the service now has a dedicated bay, and being a true (one-ended) branch there has to be linking track. Slough was already like that.

Are there any cases that go further? Where a side-route service now has to terminate at a platform further along its line, instead of running into the station? Replacing trains by trams (as at Wimbledon) shouldn't count.

I can't think of one, except by going further abroad and re-citing the re-siting of the Saint-Lazare platforms at Ermont-Eaubonne. This was an odd station all along, with extra lines joining the main through ones at both ends. French Wikipedia has before and after diagrams, which helps:

The Paris-Nord lines divide and there's a track pair and two platforms for each west-bound line. Both are suburban, though the Pointoise line is still called "Dieppe" despite being cut short at Serqueux ages ago. The southern line to the east, now the RER C, is the bit that branches off by the Eiffel Tower and crosses the Seine on a curved bridge, before trundling through the basements of north-west Paris. It also has a link into Paris-Nord, which was used by a circular service pre-RER. The southern line to the west goes to St-Lazare, and its service terminated here and could not get onto the main line anyway. The RER also served a bit of this line before disconnection.

Having decided that the RER and Paris-Nord suburban service to Pontoise needed more than their two platforms, some quite serious engineering was applied to transferring the third pair to the RER and building new platforms on the road bridge and embankment instead (about 200M€, including the station itself).

Now, is there anything like that round here?

Liskeard always has ... to get to the Looe train you leave the main station, and cross a 'road' to the branch station.

On the subject of Bradford, there is of course the Wortley West Curve in Leeds - not that short, but notorious for having been closed without the statutory closure procedure.

The St Albans platform at Watford Junction was cast into outer darkness, but sideways, and without severing the track.

Paddington...
If I remember rightly some time ago, perhaps in the 70's, weren't the stop blocks moved some yards closer to Penzance to make to concourse bigger?

Epsom Downs station was resited 21 chains closer to London Victoria in late 1989.

Wrexham Central?

Given the alignment of the station points north west, it would be more correct to say they were moved 70 yards closer to Birmingham (Snow Hill of course!)

Honeybourne North Loop Junction (worked from Station South Box after 1933) to Honeybourne East Loop Junction was, I believe, about 700 yards.  Closed in 1968 with the end of what had been the Worcester to Stratford upon Avon/Leamington/Birmingham Snow Hill services.  The branch from Honeybourne Station South round to Honeybourne West Loop remained open (but not much used) for passenger trains until the whole route suddenly shut in 1976
