TRESPASSERS on the line are causing delays between Ascot and Reading this evening.

Shortly before 5pm, National Rail reported that South Western Railway services would be disrupted until 7pm.

Network Rail staff have been informed of the trespassers on the line, and all trains in the area have been brought to a standstill.

If necessary, the electricity supply to the track may also be switched off.

Trains may be diverted via an alternative route, but currently there is no indication as to when the line will re-open.
