In the wake of the Metro-North accident, NJT’s C3RS PRT developed a correction action (presented March 24, 2014) recommending installing Approach Permanent Speed Limit Signs at locations where there is a 30MPH or more drop from Maximum Authorized Speed. At that time, the Support Team indicated that it had a more effective solution, Cab Signal Indication Code Reduction, a.k.a. “phantom code drops” utilizing the existing cab signal system. We also submitted a list of 9 locations that the PRT felt were a priority.

The PRT has been informed that our Recommended Corrective Action has been approved and the installation of the signs and code drops has begun. A list of sites will be published by NJT in the next few weeks.
