CTA Red-Purple Line alternative: Modernization 4-Track

Moderization 4 Track Alternative.JPG

This alternative would provide modern amenities at stations, extend the useful life of the system for the next 60-80 years, increase speed and reliability, and address safety and accessibility concerns. This alternative would require significant right-of-way acquisitions.

Estimated cost
$4.2 billion

Longevity
60-80 years

Evanston Branch
Stations would be reconstructed or renovated to meet modern standards for accessibility and safety including modern platform widths and clear lines of sight, in addition to being expanded to accommodate 8-car trains. Reconstruction of elevated structures and viaducts would bring them up to modern standards including clearances for cross streets underneath viaducts.

The current sloped embankment structure would be reconstructed and viaducts would be replaced as required. Minimal acquisition would be required to straighten curves that currently slow service.

The potential exists to consolidate stops while providing additional access points; examples of this could include: adding a Washington entrance to Main station and removing South Boulevard station; and adding a Gaffield entrance to Noyes station and a Church entrance to Davis station and removing Foster station.

North Red Line

Stations would be reconstructed or renovated to meet modern standards for accessibility and safety including modern platform widths and clear lines of sight. This alternative would provide express and local service in both directions by maintaining 4-tracks. This alternative would allow for potential expanded hours of express service.

Substantial additional right-of-way would be required to increase platform widths and
provide clear lines of sight, as well as to straighten curves that slow service. This
alternative would replace the existing embankment structure with a modern concrete
aerial structure.

The potential exists to consolidate stops, while providing additional
access points. Examples of this could include:

  • Adding an Ainslie entrance to Argyle station
    and removing Lawrence station.
  • Adding a Glenlake entrance to Granville station and a
    Hollywood entrance to Bryn Mawr station and removing Thorndale station.
  • Providing additional access to Howard station at Rogers Avenue and removing Jarvis station.
