Evaluation of the Train Signal and Rail Systems for the Anton Anderson Memorial Tunnel

摘要

In June 2000, the State of Alaska Department of Transportation and Public Facilities (DOT/PF) completed construction of the Whittier Access Project. One phase of this project converted the existing 2.5-mile Anton Anderson Memorial Railroad Tunnel (or Whittier Tunnel) into the world's only dual-use highway/rail tunnel with one-way reversible highway traffic. The construction project included construction of the tunnel invert (driving surface that can accommodate both highway vehicles and trains); drainage systems; three different types of ventilation systems; two vehicle staging areas; Tunnel Control Center (TCC); communication systems; portal buildings; train signal system and other safety features. The primary objective of this research project is to: 1) identify the problems affecting the train signal and rail systems and 2) develop the Scope of Services for an engineering consultant contract to determine the causes of the train signal system failures and develop solutions.
