A press release from the Federal Railroad Administration; September 12, 2018:
WASHINGTON – The U.S. Department of Transportation’s Federal Railroad Administration announced today Notice of Funding Opportunity (NOFO) for at least $46 million for Positive Train Control (PTC) Systems Grants. This NOFO represents the balance of the $250 million PTC Consolidated Rail Infrastructure and Safety Improvements (CRISI) Program that remained after selections were announced in August. 
The purpose of the NOFO is to solicit applications for at least $46,301,702 million in PTC Systems Grants to fund the deployment of PTC systems technology for intercity passenger rail transportation, freight rail transportation and/or commuter rail passenger transportation. Eligible projects include: back office systems; wayside, communications and onboard hardware equipment; software; equipment installation; spectrum; any component, testing and training for the implementation of PTC Systems; and interoperability.
“This expedited solicitation will provide commuter and intercity railroads an additional opportunity to request grant funds for positive train control,” said FRA Administrator Ronald L. Batory. “By reissuing these funds, FRA is showing our continued commitment to work with railroads and suppliers in fully implementing PTC.”
Under this second solicitation, applications are due by 5:00 p.m. on October 12, 2018, 30 days after the NOFO is published in the Federal Register.
