SECTION 011100 - SUMMARY OF WORK

PART 1 - GENERAL

1.01 DESCRIPTION OF SYSTEM

A. MARTA System

The MARTA rapid transit rail system has 48 miles of track route and 38 rail stations located on four (4) service lines. The tracks for the system are a combination of elevated, ground-level, and underground track. Propulsion power for the rail cars is provided by Traction Power Substations (TPSS) located at the passenger stations and, in some cases, midway between two (2) passenger stations. MARTA tracks are powered by 49 main line and three (3) yard TPSS where the AC utility voltage (19.8 kV) is converted to nominal 750 volts DC for distribution to the rail vehicles.

B. Traction Power Electrification System

The MARTA traction power distribution system is an ungrounded design to minimize the amount of stray current produced. The running rails and the contact rail are electrically isolated from earth or the grounding circuit through the use of special supports, rail fasteners and pads, well drained ballast and inverts, and electrical isolation from switch machines, wayside equipment, and the train control system. In addition, rail-to-rail bonding and cross bonding between the tracks is installed to increase the conductivity of the negative return circuit and manage the magnitude of the track-to-ground voltage.

C. Stray Current Control of Direct Current Powered Rail Transit System Maintaining the effectiveness of stray current and corrosion mitigation is an integrated process that involves the following primary steps:

1. Detection – Monitoring to identify deficient conditions.

2. Identification – Troubleshooting to identify the cause/source of the deficient condition.

3. Threat Assessment – The probability of a failure of ‘x’ consequence resulting from the failure, utilized to prioritize the corrective actions necessary to remediate the deficient condition.

4. Corrective Action – Preparation and execution of a corrective action plan to remediate the deficient condition.

5. Documentation – Documenting the completion of the process steps and resolution of the deficient condition.

1.02 DESCRIPTION OF WORK

A. The Work generally consists of the design, installation, testing and commissioning of a monitoring system, that consists of both hardware and software, to measure and monitor voltage across track segments at TPSS locations identified by the Track Isolation Integrity (TII) Program.
