Trainshed Ventilation Improvements (Component #3)
The Platform Level/Trainshed at CUS has ventilation concerns that stem from the absence of a coordinated mechanical ventilation system along with a deficient volume of ventilation. CUS, with below grade platforms and tracks, has over a mile of overbuild that encloses the platform/trainshed, causing stagnant smoke and diesel exhaust to accumulate. The lack of natural cross ventilation, along with insufficient mechanical ventilation, exacerbates the ventilation problem. The ventilation project would also advance Amtrak’s ability to address the urgent need to remove failing plenums. A recent ventilation study conducted in 2020 has shown true promise for rectifying the stagnant diesel exhaust and providing a code compliant emergency ventilation system. The scope of Project activities for this component includes Preliminary Engineering, NEPA, and Final Design. Please see Appendix 11 for a map of falling concrete incidents at CUS.
