Our Railway Surveying Expertise
Trusted by industry leaders.
Underhill has delivered professional railway surveying throughout our century long history. We’ve worked with Class I freight railways, TransLink, and industrial developers across Western Canada.
Our eRailSafe certified crews use UAVs, 3D scanners, LiDAR, mobile mapping, rail geometry trollies and 360° imaging tools to complete surveys safely and precisely.
- Heavy rail operators rely on us for maintenance surveys and emergency response data.
- We supply accurate data for rail alignments, bridge positioning, and structural design support.
- Transit operators such as Translink trust our precision and responsiveness for Skytrain and rapid transit corridors.
- We help crews stay on track with real-time layout, deformation monitoring, and clearance assessments.
