A mixture of tutor input, videos, syndicate work and practical demonstrations on a model railway will be used to build up the knowledge base required. The training can be consolidated with case studies and syndicate exercises, using the model, to apply the learning to a realistic situation. Delegates can be assessed on the basis of an individual written test.

Intended For:

Managers, project managers, professional, technical and supervisory staff who will be involved in the planning, design, management or execution of work in the rail industry
