The scope of this project included the construction of 8 kilometers of double track LRT, 3 direct fixation diamond crossovers, 1 ballasted crossover, 1 ballasted turnout, 5 road level crossings, and flash butt welds.  A&B Rail Services partnered with SNC Lavalin for construction of the track through the road crossings, elevated guide ways and trench, and tunnel guide ways.



  • 8 km of double ballasted track
  • 3 direct fixation diamond crossovers
  • 1 ballasted crossover
  • 1 ballasted turnout
  • 5 road level crossings
  • Flash butt welds


The Result

A satisfied client and another quality project completed.

This time sensitive project is a prime example of A&B Rail Services expertise and, capabilities to execute in a step grade site. The infrastructure work on Calgary’s West LRT required our crew to work in confined spaces including tunnels, sometimes at night, and logistical coordination in challenging locations.

What this means for the City of Calgary is that their current West LRT system and community will now be connected to the rest of the LRT network and communities.

For A&B Rail Services, it means another satisfied customer in our 50-year journey to become Canada’s largest, most-experienced and most sought-after rail services company.
