Project Description

North Main Line - RPM The purpose of the Red and Purple Modernization (RPM) Program is to expand capacity to meet growing ridership demand; reduce travel times; improve access to job markets and destinations; better utilize existing transit infrastructure; bring the existing infrastructure to a state of good repair; and improve access to the system for patrons with disabilities.

FY2021-2025 funds will continue RPM Phase One funding stream.
Red Purple Modernization phase one project consists the following interrelated and concurrent projects, as defined in the environmental documents to be developed by the CTA:

RED-PURPLE BYPASS PROJECT. This element would construct a fifth track bypass flyover immediately north of the CTA Belmont Station to separate northbound Brown Line trains that currently conflict with southbound Purple Line trains and both northbound and southbound Red Line trains. This project includes construction of a new fifth track bypass flyover and replacement or renovation of approximately 0.3 mile of associated mainline track.

LAWRENCE TO BRYN MAWR MODERNIZATION PROJECT. This modernization project would replace 1.3 miles of the existing rail line from Leland Avenue on the south to approximately Ardmore Avenue on the north. This section of track includes four stations - Lawrence, Argyle, Berwyn, and Bryn Mawr. The project would expand and modernize these four stations. The project would also provide ADA access to transit customers with disabilities in a two-mile stretch of the north Red Line that currently does not have accessible stations.

CORRIDOR SIGNAL IMPROVEMENTS. This project would improve the signal system and special trackwork generally between Belmont and Loyola stations. Improvements would occur within CTA's existing right-of-way. The scope of work includes planning, design, procurement, and installation of wayside equipment and special trackwork that are significantly past their useful lives. This project also includes improvements to existing special trackwork.

CONTINUED INTERIM CAPITAL IMPROVEMENTS. This project would improve track infrastructure conditions between Belmont Station and Linden Station in order to maintain service along existing rail lines. This work would take place within the CTA's existing right-of-way.
