Train services in Cornwall are to be improved with the multi-million pound upgrade of rail lines.
The government has said eight miles of single-track line between Probus and Burngallow will be extended to two tracks.
Work on the £15m project will begin in the winter of next year and will be finished by 2006.
Objective One funding, which gives European cash to low-income areas, is providing £3m and the Strategic Rail Authority is putting in £12m.
Cornwall has been lobbying for the upgrade for years.
The improvements will cure a bottleneck on the Penzance to London line.
However, another stretch of single track, between Truro and Falmouth, will not be upgraded.
