Having read about South Western Railway’s 6+ year delay in putting into service 90 trains costing £1 Bn, UK railway projects might like to consider changing from RAG status to using a more familiar  ‘traffic light’ system used across the network.

RAAG Status

Green – indicates that the project direction is clear and you can proceed at the maximum speed allowed.

Double Yellow – indicates a preliminary caution and that you should expect a Yellow at the next status update.

Yellow – indicates that you should slow your approach and take tasks at a restricted speed and be prepared to stop at the next status update.

Red – indicates that you should stop because there is something getting in the way of progress.
