The federal government has approved a nearly $1 billion loan to the Metropolitan Transportation Authority to improve safety on Metro-North and the Long Island Railroad.
It's the largest loan in MTA history—meant to pay for positive-train-control systems.
The new technology is designed to reduce human errors that lead to derailments and train collisions.
Officials say positive-train-control could have prevented incidents such as 2013's deadly Metro-North derailment in the Spuyten-Duyvil section of the Bronx.
Congress mandated the technology be installed on commuter railroads in 2008.
The MTA will have over two decades to repay the loan.
