However, in 1899 the London extension of the Great Central Railway was opened through Woodford Halse which brought extra traffic.

Great Central services reached Byfield via Woodford South Curve which was built at the same time.

[2] Bradshaw's timetable for August 1899 shows the 5.20pm from Marylebone terminating at Byfield, where it arrived at 7.36pm, 11 minutes after calling at Culworth.

[2] The curve was officially closed on 22 October 1900, but the rails remained in-situ for many years afterwards although the points were disconnected.

A single platform which is partly buried, and the foundations for the old goods shed which are in a severe state of decay, are all that remains of the railway station.
