How crews will track Crosstown vehicles

Find out how magnetic detection will be used to track Crosstown LRT vehicles.

Feb 25, 2020

Crosstown has a certain magnetic quality.

More specifically, that attraction is captured in axle counters that are now being installed onto Eglinton light rail transit (LRT) rails. The devices are part of the automatic train control system that uses magnetic detection to track train wheels passing over top.

Here’s an example of the first axle counters being installed on Crosstown rails. (Metrolinx photo)

The magnetic counters are silent watchmen that click off and account for the movement of each light rail vehicle car – even monitoring which direction they are heading in. This way, transit officials know when a section of rail is clear or occupied.

The equipment is grounded in safety for the system – they are actually a backup detection method – and you can see one of the axle counters below.

While we’ve given you a look at a small piece of equipment that will do a big job on Crosstown, let’s go bigger – much bigger – for another recent photo.

This one is a dramatic image from Oakwood station, which is now in the process of installing waterproofing and constructing the final arch for the station cavern.

The yellow strips are the waterproofing material.

To really get an understanding of the size of the cavern, take a look at the two Crosslinx Transit Solutions construction members standing toward the upper-middle of the photo.

Size counts – both big and small – on Crosstown.
