Petition for Waiver of Compliance

Under part 211 of Title 49 Code of Federal Regulations (CFR), this provides the public notice that on November 7, 2017, Denver's Regional Transportation District (RTDC) petitioned the Federal Railroad Administration (FRA) for a waiver of compliance from certain provisions of the Federal railroad safety regulations contained at 49 CFR 236. FRA assigned the petition Docket Number FRA-2017-0118.

In accordance with 49 CFR 236.588, RTDC is requesting approval to perform periodic testing of the Automatic Train Control system (ATC) at an interval of 92 days for the RTDC fleet of electric multiple unit equipment (EMUs), numbered RTDC 4001 through RTDC 4066. Currently RTDC is performing ATC periodic testing at an interval of 60 days as required by 49 CFR 236.588. In support of this request, RTDC states that the original equipment manufacturer (OEM) Siemens Rail Automation (formerly PHW, Inc.) has developed the maintenance and testing program for these vehicles based on a 92-day interval. RTDC has included relevant portions of this program with its petition. RTDC further states that to date, there have been no issues with the ATC system found during periodic testing that would be impacted by increasing the testing interval to 92 days. RTDC adds that granting the requested approval would not result in an additional costs and would allow RTDC to improve efficiency and resource allocation while complying with the OEM's maintenance requirements.
