REVISED AM-1


C. Exceptions and Clarifications to The Criteria

1. Applicable portions of The Criteria shall be used to guide the planning and design of the proposed facility. While planning this project, the Authority has changed or over-ridden certain requirements of The Criteria. The various chapters within Book 2 describe specific project requirements that may over ride or supplement specific requirements of The Criteria.

D. Functional Requirements

1. Test Track

a. The Test Track shall be used by WMATA and WMATA’s vehicle suppliers to test new rail cars before they are put into revenue service. Used in conjunction with the Commissioning Facility, cars will be moved from the Commissioning Facility in the Green Belt yard on the inbound Green Line track, to a new switch located near the Green Belt station. Once on the test track, the cars will be separated from all revenue trains on the Green Line. The new cars are married pairs with an arrangement where two 75-foot long cars are semi-permanently coupled together. Typically, some electrical or mechanical systems are shared between the two cars. The intended testing configuration will be one or two sets of married pairs (two or four cars). Tests to be performed on the cars on the test track include: 1) Acceleration, at maximum rate, to 75 miles per hour, then braking to

a stop

2) Brake testing from various speeds

3) Multiple aspects of the Automatic Train Control (ATC)

4) Stops at a phantom station

5) Other tests that are to be determined at a later time

2. Commissioning Facility

a. The Commissioning Facility will be located in the south eastern part of the Green Belt Yard. New cars will be received from the car manufacturer on an existing track in the Green Belt yard and moved to the Commissioning Facility. Once inside the facility on one of the two tracks, the cars will be thoroughly inspected and tested. During this process some components may be removed and replaced on the vehicles. Sets of portable jacks are required for this purpose to be supplied by others.
