About this file

This document is a technical appendix for flagmen requirements issued by the Chicago Transit Authority (CTA) as part of Invitation for Bid (IFB) C25FI103184211R for construction services related to the All Stations Accessibility Program (ASAP) at Logan Square Line - California Station. The appendix provides comprehensive guidelines for flagmen deployment across the CTA's entire rail system, which spans multiple lines including the Blue, Brown, Green, Orange, Red, Purple, and Yellow lines. The document establishes 198 flag zones distributed across seven rail terminals and their respective line segments, detailing the specific flagmen requirements based on track configurations, track characteristics, and work zone locations. Each flag zone is indexed with location boundaries, number of tracks, special conditions, rail stations within the zone, and minimum flagmen requirements determined by either the "Tracks Fouled" method or "Track Numbers" method. The flagmen requirements range from one to six flagmen depending on the zone complexity and number of tracks involved in the work area.

The document includes standard operating procedures for flagging operations on the right-of-way, establishing protocols for flagmen duties, equipment requirements, portable track trip installation and removal, hand signal procedures, and safety protocols. Flaggers are required to wear specified safety clothing and must never leave portable track trips or work crews unattended. Work zone setup procedures mandate that a Roadway Worker in Charge (RWIC) contact Rail Control using a 10-37 call code before entering the right-of-way, and slow zones must be established when three or more workers are present for over 60 minutes. The document emphasizes that safety is integral to all flagging operations, with workers required to face approaching trains and immediately evacuate the right-of-way if trains do not respond to flagging signals. Shunt cables, portable track trips, and electronic train warning devices are specified safety equipment to be installed at designated locations to ensure proper train stopping distances and worker protection throughout the work zone.

FLAG ZONE INDEX

The entire Rail System has been divided into 198 flag zones. These flag zones are based upon which Rail Terminal has the responsibility of providing flagmen. The Flag Zone numbers emulate train run numbers assigned to the Terminal supplying the Flagmen (except for the loop). For easy identification, all Flag Zones are listed on a "Flag Zone Index" chart.

This Flag Zone Index identifies each Flag Zone by:

1) Flag Zone Number

2) Location (limits of the zone)

3) Number of tracks

4) Track Characteristics/Special Conditions

5) Rail Stations within the flag zone

6) Flagmen Requirements based on:

a) The number of tracks fouled.

b) Track number where work is being performed.

c) Minimum number of flagmen required.

FLAGMEN REQUIREMENTS

Flagmen requirements are determined by one of two methods, Tracks Fouled or Track Numbers.

Determining Flagmen Requirements using "Tracks Fouled" Method

Tracks Fouled is defined as the placement of an individual or an item of equipment in such proximity to a track that a moving train could strike the individual or equipment. This also includes the area where workers relocate to clear the track upon the approach of a train. (Note:

climbing or jumping up to a Rail Station Platform is not an acceptable method of clearing a fouled track). Flagmen requirements are normally determined by this method. To determine the minimum number of flagmen required, ascertain how many tracks will be fouled, then refer to the Tracks Fouled portion of the Flag Zone Index for the minimum number of flagmen required.

Determining Flagmen Requirements using "Track Numbers" Method (used only in areas of multiple tracks - four or more)

Track Number is defined as a specific number or letter used to identify a specific track. This method is used when work is performed in an area of multiple tracks (four or more).

When work is performed on one track in areas of four or more tracks, the track number portion of the Flag Zone Index is used to determine the minimum number of flagmen required.

When work is performed on more than one (1) track in areas of four (4) or more tracks, the track fouled portion of the Flag Zone Index Chart is used to determine the minimum number of flagmen required.
