One of the biggest rail projects ever undertaken in the South could signal an end to years of disruption for commuters.
Multimillion-pound plans have been unveiled to improve the Brighton line, known to have the worst punctuality of any major route.
Many trains to London from Surrey, Kent, Hampshire and Sussex try to squeeze through the lines at East Croydon which is causing delays.
The solution is new track with flyovers, underpasses and a bigger station at East Croydon to ease congestion.
The proposals will take two years to develop and the project will take several years to complete.
