Tunnel Ventilation Requirements

on CBTC Operation

A world leaderFounded in 1911, SNC-Lavalin is a global fully integrated professional services and project

management company and a major player in the ownership of infrastructure. From offices

around the world, SNC-Lavalin's employees are proud to build what matters. Our teams

provide comprehensive end-to-end project solutions – including capital investment,

consulting, design, engineering, construction, sustaining capital and operations and

maintenance – to clients across oil and gas, mining and metallurgy, infrastructure, clean

power, nuclear and EDPM (engineering design and project management).

On July 3, 2017, SNC-Lavalin acquired Atkins, one of the world’s most respected design,

engineering and project management consultancies, which has been integrated into our

sectors.

• The signaling system design shall support the re-positioning of a train exposed to an external

fire

Eglinton

Ontario, Canada

The 19-km light rail line will include 25 stations and stops, linking commuters to bus routes, connections to three subway stations and various GO Transit lines. Over 10 km will run underground, and it is the largest transit expansion in Toronto’s history.

Finance, design, build, and 30-year maintenance and rehabilitation of the Eglinton Crosstown LRT.

Other CBTC Considerations

16

• No Stopping zones

• Areas where we don’t want ATP to enforce train stopping

• Includes areas where we could impact Tunnel Vent operations, such as in front of dampers or too near

portal doors

• Separation

• Keep the trains apart from each other under ATP

• Don’t let them close up to each other under congested operation

Tunnel Ventilation Requirements on CBTC Operation

17

• Conclusions

• Placing requirements on CBTC to support Tunnel Ventilation operation allows TVS design to proceed with

certainty on occupancy control and train position recovery

• Using CBTC to implement smoke alarm monitoring and recovery speeds up the response to a smoke

incident, allowing for a faster commencement of ventilation operation

• Using CBTC as a major tool on the emergency response to smoke improves compliance with NFPA-130

• Integrated approaches work best
