As part of the Rail Systems Alliance in Scotland, Carstairs junction is being remodeled to eliminate speed restrictions, accelerating and improving passenger journeys and rail performance. Arcadis is designing the electrification system to increase junction speeds from 40 to 110 miles per hour, providing capacity for high-speed services to Edinburgh and Glasgow, while reducing carbon emissions by 20% to 30%. Arcadis realized that workflows for multidiscipline design review and clash detection would be insufficient to meet the project challenges. 
 
They selected Bentley applications to establish a collaborative data environment and develop a 3D federated model, facilitating coordinated modeling and web-based virtual design reviews. Working in Bentley’s integrated digital ecosystem improved data exchange by 80%. The team identified and resolved 15,000 clashes during the design phase while reducing design time by 35% to save GBP 50 million in costs and deliver the project 14 days ahead of schedule.
