Train operating company Greater Anglia has installed 1,176 new cycle spaces across its network.
Other work to improve cycle parking includes better CCTV and lighting, to help improve safety and security.
The extra spaces have been partly funded by local authorities including Essex County Council, Fenland District Council and Cambridgeshire County Council.
This brings the total number of cycle spaces on the network to more than 10,000.
