Built on a sharp curve, the station was built as part of the original LSWR main line between London and Weymouth. S&D trains to Broadstone would have to reverse to complete their journey towards Poole & Bournemouth West.
The station consisted of two platforms, each with a bay. The up platform bay to the north, and the down bay the south. The down bay was apparently used by S&D services, although I am still trying to clarify whether this is correct.
The main station buildings were on the up platform, built mainly of brick, although the main building had numerous extensions built on during its life. The down platform had a large brick waiting canopy.
There was a large goods yard on the eastern side of the station with a large brick goods shed. At the northern end of the up platform were sidings leading to cattle pens for the nearby cattle market.

4MT No. 76019 on a service to Bournemouth West - 30th Aug 1961.
Note the height of the signal box behind the first carriage.

When the main line to Weymouth was opened via Bournemouth and Poole the line became downgraded, serving only the local trains on the Salisbury and Ringwood lines.

The station area was controlled by a tall brick 29 lever signal box located on the up platform.

This is where the Somerset & Dorset line originally, officially ended before the direct line from Corfe Mullen Junction to Broadstone was opened on the 14th of December 1885.
In the 'V' of the junction there was the S&DJR engine shed. There were originally two engine sheds here, these were replace by one large shed in 1909. This could hold up to four locomotives. There were all the usual coaling and watering facilities, along with a 44 ft 9 in turntable and drivers lodgings for up to 12 crew.
The shed was closed on the 22nd of January 1923, and the shed's duties were transferred over to Templecombe.

The junction was controlled by two signal boxes. One located at the throat of the junction controlling the LSWR line and junction, this closed in 1933 when the S&D line was closed. The other box controlling the start of the S&D single line towards Blandford. This box was located on the S&D line near the engine shed. This box closed on the 1st of April 1928.
