On February 2, a Kitchener-bound GO train derailed at low speed just outside Toronto’s Union Station. Nobody was hurt, but the derailment blocked what Metrolinx’s CEO called a “hinge point” in the network and disrupted commuter service for days, as CityNews reported at the time.

The final report, covered by CBC News in September, is worth reading for anyone who runs a rail yard, a rail-served plant or an intermodal terminal. Screws across nine consecutive timber ties were loose, missing or degraded. The rail shifted about 3.5 centimetres. And the report pointed to “limitations associated with relying primarily on routine visual inspections to identify track infrastructure degradation.”

What Did the Metrolinx Report Actually Find?

The findings are specific and, frankly, familiar to anyone who manages aging infrastructure:

• Only two screws per plate were installed at the site, where newer standards called for four.

• Visual inspections cannot “reliably determine the remaining holding strength or clamping effectiveness” of fasteners, according to the report.

• Geometry testing ran annually, and the derailment happened before the next scheduled cycle.

• The combination of visual inspections, limited inspection prompts, annual geometry testing and discretionary use of enhanced methods reduced the odds of catching the problem in time.

Metrolinx’s executive summary describes a degraded, non-compliant fastening system that allowed the track to widen under repeated load. CEO Michael Lindsay summed it up as “a legacy infrastructure condition that developed progressively over time.”

That phrase, developed progressively over time, is the heart of the matter. The defect did not appear overnight. It grew in the gaps between inspections.

Why Does This Matter for Freight Yards and Rail-Served Plants?

Most derailments in Canadian yards and industrial sidings are low-speed and never make the news. They still cost real money: re-railing crews, damaged switches, blocked tracks, delayed cars and, occasionally, product spills.

Freight operators feel this. The TSB has opened investigations into several CN main-track derailments in 2026, including one in St. Catharines, Ontario, in March, where 13 cars derailed while crossing a Welland Canal bridge, according to Railway Supply.

Private industrial track at refineries, steel mills, grain terminals and auto plants is often inspected less frequently than main line, by smaller teams, with fewer tools. If a transit agency with a dedicated engineering department can be caught out by progressive degradation, a manufacturer’s 4-kilometre internal rail network certainly can.

How Does Video-Based Track Inspection for Ontario Rail Yards Fill the Gaps?

Let us be precise. A fixed CCTV camera is not a track geometry car, and it will not measure fastener clamping force. Anyone who tells you otherwise is overselling.

What video-based track inspection for Ontario rail yards does well is give you continuous eyes on the places where problems show up first, and a time-stamped record of what changed.

Canada’s largest railway already works this way at network scale. CN’s Autonomous Track Inspection Program uses automated railcars with laser geometry measurement, 3D component analysis of ties, spikes and plates, and LIDAR, running around the clock. CN’s Automated Inspection Portals use ultra-high-definition panoramic cameras and machine vision to inspect cars at track speed. In a regulatory filing, CN reported a 90% reduction in unprotected track geometry conditions per 100 miles inspected since 2019.

Yard operators can apply the same principle at their own scale:

Interlocking and switch coverage. Fixed high-resolution cameras on switches, crossovers and diamonds, the “hinge points” of your yard, let engineering staff review movement behaviour daily without walking the track. Unusual car sway or wheel climb at a specific switch is often visible on video before it becomes a derailment.

PTZ cameras for virtual walk-downs. Pan-tilt-zoom units on light towers let a track supervisor do a quick remote check of a suspect area after heavy traffic, a freeze-thaw cycle or a heavy rain.

Inspection verification. Cameras at key track sections create an objective record that scheduled inspections happened, how long they took and what was looked at. That is not about catching people out. It is about knowing whether your inspection program is being executed as written, which is exactly what an auditor or regulator will ask after an incident.

Movement and incident reconstruction. When something does go wrong, footage shows train handling, speed and the moment of derailment. That shortens root-cause analysis and helps protect crews from unfair blame. The Metrolinx report found no non-compliant crew actions. Video makes that kind of finding faster and more defensible.

Analytics for anomalies. Modern video analytics can flag objects on track, people in the gauge, or vehicles stopped on crossings, adding protection between scheduled inspections.

How Should a 64-Camera Rail Yard System Be Laid Out?

For a mid-size classification or industrial yard, a 64-camera design commonly breaks down like this:

• 12 to 16 cameras on switches, interlockings and crossovers.

• 8 to 12 PTZ units on towers for wide-area review and virtual walk-downs.

• 10 to 14 cameras on the perimeter and access points to manage trespass and contractor access.

• 8 to 10 cameras at loading and unloading spots, where product handling and car securement happen.

• The remainder on roads, crossings, maintenance shops and fuel areas.

All of it should feed an industrial NVR platform with retention long enough to compare a switch this month against the same switch last quarter. Integration with your maintenance management system means a flagged clip becomes a work order, not an email that gets lost.

What Should Rail Yard Managers Do Next?

The Metrolinx report is a reminder that inspection programs fail quietly, in the time between checks. Pull your yard map and mark every switch and crossover your team cannot see without walking to it. Then ask how long a developing defect at each one could go unnoticed. That list is the starting point for video-based track inspection for Ontario rail yards, and for a far more defensible safety program.

FAQ

Q: Can CCTV replace regulatory track inspections?
A: No. Video supplements required inspections and geometry testing. It provides continuous visual monitoring and evidence between scheduled checks, but it does not replace qualified inspectors or measurement equipment.

Q: Which parts of a rail yard benefit most from cameras?
A: Switches, interlockings, crossovers, diamonds and loading spots, because these are where track stress, car movement and human activity concentrate.

Q: How does video help after a yard derailment?
A: Footage shows train speed, handling and the exact moment and location of the derailment, which shortens root-cause analysis, supports insurance and regulatory reporting, and helps protect crews from unfair blame.

Q: Do rail yard cameras help with safety culture?
A: Yes, when used for coaching rather than punishment. Reviewing real movements with crews helps reinforce safe practices and shows workers that the company invests in their safety.
