Since the closure threats in the 1960s there have been plans/ideas that there should be a rail halt in Great Cornard, it was even used in an objection to the planned 1969 closure:

Objection to British Railways
Gt.Cornard is accepting London overspill population and a point frequently made is that a Halt provided at Gt.Cornard would increse the use made of the passenger service.

Reply from British Railways
It is doubtful whether the provision of a Halt at Gt.Cornard which is only a short distance from Sudbury Station, would result in any net increase in rail travel.

Since those days, the project hasn't really got any further, the idea routinely appears in the local newspapers with various headlines including "Rail Halt Hopes for Great Cornard".
The scheme came back in to the public eye in 2006 when housing developer Barratt put up £100,000 in Section 106 money - this was to pay for a rail halt in return for planning permission for a large number of flats on the former Bakers Mill site.

The proposed site of the rail halt is adjacent to the Cornard Level Crossing, however such location would bring additional difficulties, mainly with the 'stike in' treadles for the level crossing.
Cornard level crossing is completly automatic, the train wheels press some treadles near the track as they pass, approx 30 seconds away, and once the train has arrived at the crossing the gates are down.

Should a platform be build adjacent to the crossing then either the strike in would need to be next to the barriers or a plunger provided on the platform for the driver to press - either method would require ALL services to Sudbury to stop at the station. The other method would be to convert the crossing to one monitered by the signal box and provide colour light signals to the driver - something which would be fairly expensive.

Train operator One Railway in 2007 rejected the idea of a crossing on the grounds that it would disrupt the timetable.
Peter Beer, parish council chairman, said the rail company was now the only thing standing in the way of the halt, which has been in the pipeline for the past 20 years.
'Even if only one or two trains stop a day, it would be a great help to the commuters, this is something the council has been campaigning for for a long time, although it only became possible recently as a result of the Barratt Home housing development," he said.
"Part of the conditions of the planning application was that the firm gave us some money towards the scheme, but One Railway has now told us it will not be possible to have the halt because it will disrupt its train timetable."
Mr Beer said the halt - which would be built at the rear of the former Baker's Mill site - was a much-needed addition to Great Cornard, and would mean more people could leave their cars at home.
"Even if there were only one or two trains stop there a day, it would be a great help to the commuters and would not mean much of a disruption to the trains," he said.
"A train would only have to stop for a couple of minutes or so, so I think One Railway is being very shortsighted.
"We have been told we have the backing of Suffolk County Council and Babergh District Council, so now we just hope we will be able to come to some sort of arrangement with One Railway so we can get this sorted out."
