Bombardier Transport

Special Features

The 60′ section had multiple customized options: insulated with side shutters, and the entire building has several airlocks to counteract the thrust of the moving train. Firewall inside the tunnel (to control wind pressure inside) when the wagon is moving. Powder-concrete foundation.

Project

Bombardier Transportation needed a 1 km long test tunnel to test its new Aur cars. The mandate required the reconstruction of a subway track identical to that of the Montreal metro using fabric buildings.
