We’ve shown you a growing gallery of pictures from deep tunnels to elevated guideways that will be used for the Eglinton Crosstown light rail transit (LRT) line.

And we’ve even given you a glimpse of the vehicles themselves.

But all that work, and those lines of rail, won’t go far without the spark of power.

Recently, before the latest snowfall in Toronto, builders Crosslinx Transit Solutions installed traction power substations (TPSS). They’re small structures that take alternating current power that’s available from normal power companies and converts it into the direct current required by the light rail vehicles.

A number of the structures will be needed along the Crosstown route, and if you didn’t know how impressive they are, you might just think they’re storage containers.

Now they’re finding their homes along the line.

As a bonus shot – because the reach is spectacular – we’ve included a recent image of the lengths Crosslinx will go to get concrete where it needs to go at Kennedy station.
