Illustrative option schemes in CP5 HLOS
Alongside HLOS, government publishes an illustrative option. This sets out the list of projects that government considers might be required to deliver the high level outputs that it specifies. Government looks to the rail industry to improve and find better ways of delivering the HLOS outputs.
