Connected driving
advice system

Achieve peak performance with a synchronised network of connected trains

A TTG Energymiser® module, MyDAS provides driving performance reports via a web application that is accessible on multiple platforms.

Sustainability is just one of the benefits

TTG Energymiser® is an automated, digital application for rail operators.
The Connected Driving Advice Systems (C-DAS) technology provides real-time driving advice reducing CO2 emissions, energy consumption and costs as well as improving on-time performance.
It seamlessly integrates with mission critical digital signalling and traffic management systems and rail management solutions including planning and scheduling and workforce management. Suitable for any train including passenger, freight, light rail & heavy haul.

Learn how TTG Energymiser™ will deliver better operational and sustainable outcomes for rail operators.


Real-time driving advice decreases energy use, saves money, and reduces greenhouse gas emissions which helps your rail organisation meet its decarbonisation targets. TTG delivers performance and sustainability improvements to leading railways and manufacturers, including SNCF (France), KiwiRail (New Zealand), and First Group, Arriva, Abellio and rail operators run directly be the UK Government (United Kingdom).


Energy use can be half of a locomotive’s lifetime operating cost and can vary significantly between drivers. Optimal driving modes increase efficiencies and reduce costs. It has achieved over 10% energy savings for passenger and coal trains in the United Kingdom, 9% for heavy-haul iron ore trains in Africa, and over 10% for freight trains in Australia, the United Kingdom and India.


Achieve better rail asset use and improve operations. TTG solutions optimise rail trips, ensuring the most efficient stop-to-stop travel. Providing optimal driving advice helps extend the life of rail assets by reducing wear and tear on trains and tracks. This in turn minimises the maintenance costs caused by braking and overspeeding, which are factors that significantly affect equipment lifespan.


TTG’s solutions boost rail network capacity and performance by improving on-time running to critical timing point locations such as junctions and passing loops. This is especially important for complex and congested networks with a mix of passenger and freight services. Simulation studies, trials and proof of concepts can be undertaken before our solution is adopted.


C-DAS aligns with rail industry demands to automate and digitally connect operations. It integrates with other digital systems including signalling and traffic management systems, such as ETCS, ATMS, and PTC, that manage the efficiency and safety of rail operations. It also integrates with other rail solutions including planning and scheduling and workforce management software.


TTG’s technology can be easily retrofitted and does not involve extensive configuration or large-scale capital investment. It has been used on railways in Europe, Australia, New Zealand, China, India, South-East Asia, Africa, and the USA. TTG can provide cloud or on-premise hosting. Depending on the rail operation, the payback period is approximately one to three years - a fast return on investment.
