A maintenance policy powering performance
Assets are vital to the ongoing success of public transport systems. Implementing solid maintenance regimes is key to delivering safe operations, high quality services and optimising the financial performance of public transport networks.

At Keolis, we look after critical assets to optimise their use and anticipate breakdowns in order to boost operational performance.

Keolis’ maintenance regime is underpinned by three main principles:

  • Preventive Maintenance – regular procedures put in place to prevent deterioration or breakdown;
  • Condition Based Maintenance – monitoring performance and maintaining the equipment. The intention is for components to be changed before they fail; and
  • Reliability Centred Maintenance – managing maintenance frequency and content with the objective of avoiding failures, to achieve high levels of reliability and availability for service.

Enhance asset reliability

Reliable assets are crucial to maintaining operational performance and delivering high quality services. At Keolis we have acquired considerable expertise in developing reliability focused maintenance regimes to predict and prevent the breakdown of critical assets.
In stations, we strive to ensure that all ticketing facilities, including ticket machines, gates, lifts and escalators are available to facilitate the passenger journey.
We leverage the value of data collected automatically by sensors installed on fixed and rolling assets to develop remote monitoring, predict systemic failure more accurately and make decisions driven by the integration of data collection devices and analytical tools.

Effective and rapid response to incidents

If a failure does occur, we strive to restore the service quickly and effectively to reduce the impact on passengers to an absolute minimum. We are able to respond quickly to incidents or systems breakdowns and strengthen the availability of the service by:

  • Robust incident response procedures to limit impact on operations, reduce recovery time and costs
  • Highly integrated operations and maintenance teams allowing rapid return to normal operations for most incidents
  • Development of highly experienced and skilled incident response teams for most serious disruptions
  • Procurement and management of service contracts with good geographical coverage to ensure customer facing equipment such as ticket machines, lifts or escalators can be restored quickly in the event of system failure 

Contribute to network modernisation

Assets don’t only need to be maintained properly. Evolving customer expectations, growing pressure on network capacity, high asset utilisation; all these factors mean assets need to be refurbished, modernised and replaced as part of asset management programmes.


Keolis commits to working together with local transport authorities to identify opportunities for network improvement and implementing asset modernisation programmes that are robust, targeted and achievable. Our priority when developing these programmes is to make sure performance continues to improve, economic efficiency is increased and investment is prioritised appropriately. We provide value engineering to local transport authorities, especially in relation to:

  • Automation programmes for existing lines
  • Capacity enhancement programmes
  • Asset improvement and replacement programmes
  • Line extension programmes.


Whole lifecycle view of costs

Effectively replacing assets at the most appropriate time with value-based, cost effective solutions is critical for those metros with an ageing asset base, where replacement costs might accumulate. Taking a lifecycle view of costs can make a substantial difference to both investments and operational expenditures.

At Keolis we have developed efficient data-driven decision making tools, which we share with local transport authorities to determine whether rehabilitation, overhaul or replacement will be used to ensure the operational performance and longevity of the asset.

Boston combines maintenance and augmented reality

In June 2016, Keolis Commuter Services launched an innovative pilot project in Boston by equipping maintenance staff with augmented reality glasses. Field mechanics use the smart glasses to stream video and converse in real time with remote expert technicians, meaning repairs can be handled faster, improving service quality across the network.
