What we do

One rail specialist.
Every critical measurement.

We combine field expertise, purpose-built rail technology and disciplined data management to give infrastructure owners and project teams confidence in what is happening on the ground.

01

Track survey & geometry

High-accuracy GEDO trolley surveys for geometry, alignment, clearance and as-built verification.

GEDOGauge & cantClearance
02

Monitoring

Automated, manual and remote sensor monitoring built around active rail environments and project risk.

ATSRemote sensorsReporting
03

LiDAR & reality capture

Mobile, trolley and UAV LiDAR that turns complex corridors and structures into usable engineering data.

Point cloudsUAVChange detection
04

Survey control

Robust control networks, precise levelling and GNSS solutions designed for repeatable rail delivery.

Technology in the field

Purpose-built tools.
Rail-ready results.

We select the right collection platform for the asset, access window and required deliverable—then turn the captured data into clear information your project team can use.

System 01

Trimble GEDO
track survey system

A rail-mounted measurement platform for efficient track geometry, alignment and clearance surveys in open track, urban transit and tunnel environments.

  • Gauge, cant, twist and track geometry
  • 3D rail strings and as-built alignment
  • Clearance and tunnel envelope analysis
  • OCS height and stagger measurement

System 02

Flyability Elios 3
confined-space drone

A collision-tolerant caged drone that brings visual inspection and LiDAR mapping into dark, inaccessible or hazardous assets without putting personnel inside them.

  • Culverts, bridge interiors and tunnels
  • 4K visual and thermal inspection imagery
  • LiDAR point clouds and 3D asset mapping
  • Geolocated observations, video and stills

System 03

Track & structure monitoring

Automated total stations, precision targets and remote sensors provide repeatable movement data during construction and over the longer term.

UAV mapping & LiDAR

Aerial mapping and classified point clouds capture corridors, bridges and surrounding terrain for engineering, inspection and change analysis.

Processed deliverables

Captured once.
Used many ways.

From classified corridor models to tunnel clearance envelopes, our outputs are structured around the engineering question—not the sensor.

From field to decision

Data you can
act on.

Collection is only the start. We validate, process and communicate complex rail data so decisions can be made quickly and confidently.

Why Summit

Independent by design.
Rail-focused by choice.

Summit Infrastructure is a Calgary-based specialist providing survey, monitoring and geospatial services to the Canadian rail sector.

Because we do not design or build the asset, our clients receive clear, independent information focused on accuracy, safety and the needs of the railway.
