Upon successful completion of the 4 day course (5 days if OLP/CRP modules are required), the candidates will be able to interpret correctly the relevant parts of the Rule Book, the Railway Group Standards and will understand the relevant aspects of the Sentinel Scheme procedures appertaining to COSS duties.

They will be able to demonstrate their understanding and ability to set up and maintain a safe system of work before any group of staff are allowed to go “On or Near the Line”.
