Positive Train Control Testing Starts Tonight
Posted on 04.26.19
RTD and its concessionaire Denver Transit Partners (DTP) will be updating and testing positive train control (PTC) software starting tonight as part of the Federal Railroad Administration (FRA) Grade Crossings Continuous Improvement Action Plan. DTP has to shut down the PTC and operate with automatic train control (ATC) in order to do the testing. This means that starting tonight and through Tuesday night from 12 midnight-3 a.m., trains will need to sound their horns on the University of Colorado A Line as they go through the grade crossings. This is expected to be four train trips during this timeframe.
DTP has planned this testing during this timeframe to minimize train horns as much as possible. While this is an impact to you and your neighbors along the A Line, this plan prevents all trains from having to sound horns during other operating hours, which is a much more significant impact.
Testing will be from April 26 – May 1 during the hours of midnight to 3 a.m. each night. If the testing is not completed by 3 a.m. Wednesday, May 1, testing will be extended and monitored on a day-by-day basis.
The software update and testing is necessary for efficient and reliable operation of PTC all in the name of safety.
We apologize for the disruption and inconvenience you have endured. We do understand the impact and are anxious to implement the quiet zones as intended.
