Therefore, the philosophy of the project team is to maintain infrastructure only when intervention is needed, instead of the now common schedule driven maintenance strategies. To achieve a step change, improvements must be made to railway infrastructure maintenance approaches through:

• Increased reliability - This can be accomplished by means of more effective maintenance, which is achievable by improving inspection and monitoring capabilities;
• Increased availability - This can be accomplished by reducing possession times, which is achievable by automating and optimising maintenance planning and scheduling, and also by speeding-up maintenance activities; 
• Increased maintainability - This can be accomplished by reducing the time taken to install and maintain infrastructure, which is achievable by identifying tasks that lend themselves to automation and then developing and introducing appropriate technology;
• Improved worker safety - This can be accomplished by reducing the need for track workers to carry out tasks on or near the line, which is achievable through automated inspection techniques and the development of modular infrastructure
