In accordance with Part 211 of Title 49 Code of Federal Regulations (CFR), notice is hereby given that the Federal Railroad Administration (FRA) has received a request for a waiver of compliance from certain requirements of its safety standards. The individual petition is described below, including the party seeking relief, the regulatory provisions involved, the nature of the relief being requested, and the petitioner's arguments in favor of relief.
Metropolitan Transit Authority
The Metropolitan Transit Authority (MTA), on behalf of the Long Island Rail Road (LIRR) and Metro-North Commuter Rail (MNCW), seeks approval for a waiver of compliance with the requirements of the Passenger Equipment Safety Standards contained in 49 CFR 238.105(d)(1), train electronic hardware and software safety. Section 49 CFR 238.105(d)(1) states that:
“Hardware and software that controls or monitors a train's primary braking system shall either: (I) Fail safely by initiating a full service brake application in the event of a hardware or software failure that could impair the ability of the engineer to apply or release the brakes; or (ii) Access to direct manual control of the primary braking system (both service and emergency braking) shall be provided to the engineer.”
This waiver is for over 1,000 M-7 electric MU's already being operated over LIRR and MNCW. The braking software provided by the manufacturer only partly meets the above requirements. The railroad requests that an application of only emergency brakes in the event of a loss of power, or failure (hardware and software), of the friction brake control unit be allowed in lieu of either the requirement for a full service brake application or restoration of direct manual control of the primary braking system to the operator.
The electric MU locomotives brake systems were provided by Knorr Brake Corporation and the electronic control logic was provided by Mitsubishi Electric Company. The railroad explains in their petition that the full service brake application is transmitted electronically to an analog converter which provides pneumatic brake force through application and release magnet valves. Emergency brake function is provided by venting brake pipe to initiate a trainline brake application. Emergency brake application can be initiated via the Master Controller, the B3C conductors valve, or by loss of trainline power to the emergency magnet valve circuit causing trainline to vent to atmosphere causing the brakes over the entire consist to apply at an emergency rate.
