Please note:

Background information:

Network Rail are renewing level crossings and signalling between Shalford and Gomshall for a safer, more reliable railway.

From Sunday 14 to Saturday 27 September 2025 Network Rail will be completing the final stage of their re-signalling on the line. In addition, at Burrows and Brook level crossings, new barriers will be installed that cover the full width of the road as opposed to just half.

Once all of the physical components are in, testing will be conducted to make sure the new signalling system and level crossings work as intended, ready for the re-opening of the line.
