Thorpe Culvert

Due to increasing deterioration of the signal box structure Thorpe Culvert will need to be demolished and replaced. English Heritage have asked that a replica G.N.R. box be constructed. In the interim the signalling and level crossing gates will be replaced by modern equipment controlled from a small panel.

20/10/02: New colour light signals and new barrier crossing were commissioned, controlled from small panel in existing SB.

8-9/02/03: Panel moved into new temporary signal box (Portakabin on top of relay room). Original Signal Box to be demolished over the following weekend to make way for construction of the replica.

Many "searchlight" colour light signals to be abolished under this scheme.

Bournemouth Area Resignalling

The opening of the Bournemouth Area Signalling Centre has resulted in the closure of the existing boxes at Bournemouth and Branksome. Control of all the signalling between New Milton and Parkestone has passed to the new Signalling Centre which has a Siemens SIMIS W computer based interlocking using axle counters instead of track circuits.
