Droitwich Spa Junction

The junction sees the Birmingham to Worcester via Bromsgrove Line branch off from the main line - the Birmingham to Worcester via Kidderminster Line. Part of this line is a surviving section of the Oxford-Worcester-Wolverhampton Line and is these days used by trains heading towards Kidderminster, Stourbridge Junction and Birmingham Snow Hill. The branch meanwhile joins the main Birmingham to Bristol line at Stoke Works Junction, south of Bromsgrove - services over this line then continue via the famous Lickey Incline en route to Birmingham New Street.

Droitwich Spa signal box controls the junction and is located between the diverging lines. The whole of the junction is controlled by semaphore signals from the British Rail Western Region era. The box interfaces with the West Midlands Signal Control Centre, Stourbridge Desk (at Saltley) on the main line towards Kidderminster and West Midlands Signal Control Centre, Bromsgrove Desk (at Saltley) on the branch, using the Track Circuit Block system - the latter becomes a single line just beyond the junction and remains so until joining the main line at Stoke Works. To the south, the next box is located at Worcester Tunnel Junction, north of Worcester Shrub Hill, signalled via the Absolute Block system.
