Part of Network Rail's Railway Upgrade Plan includes a project to replace a section of railways between London and Gatwick Airport and replace a bridge on the Brighton Main Line.

From now, there will be no trains between Croydon and Redhill from 10pm on Christmas Eve through to 4th January 2016.

To ensure there are minimal passenger disruptions during this time, there will be a mixture of diversions and rail replacement buses.

Speaking on the upgrade to this area, Network Rail route managing director Alasdair Coates said that the company's "engineers will be working around the clock over Christmas and New Year to replace an entire junction at Purley".

The aim of these changes is to "improve reliability and comfort for passengers" across this Network Rail service.

The project at Purley will see the junction, which sees lines from Tattenham Corner, Caterham, Redhill and Gatwick Airport meet each other, replaced with modern track and signalling equipment.
