Zelra’s DAS solution – FAQ
Zelra’s DAS (Driving Advice System) provides real-time speed guidance to train drivers, helping them reduce energy use, improve on time running, and lower carbon emissions. The system optimises braking, acceleration, and coasting to deliver more energy efficient and reliable journeys.
The system generates and continuously adjusts an optimal journey profile based on:
• Track geometry and speed limits
• Timetable and train characteristics
• Real-time train position
Drivers receive in-cab advice that adapts to route conditions, improving consistency across operators and reducing unnecessary braking and acceleration.
Zelra’s DAS is trusted by leading rail operators including:
• SNCF (France)
• ScotRail (UK)
• Greater Anglia (UK)
• KiwiRail (New Zealand)
Zelra’s DAS includes detailed route statistics and journey reports for individual drivers and teams. These reports support driver training, especially when transitioning to new rolling stock or routes. Metrics include trip time, speed compliance, and dwell times.
Zelra also provides DAS training for staff and union representatives to create driver champions who support system adoption.
Zelra’s C-DAS (Connected Driving Advice System) builds on Zelra’s DAS by enabling real-time communication between trains and network systems. This enhances coordination and performance across the rail network.
