Lawmakers in Connecticut say the deadly train crash in Hoboken, New Jersey is further proof that more safety is needed on railways across the nation.

Sen. Richard Blumenthal and state Sen. Tony Hwang, of Fairfield, say railroads should already be using positive train control technology. The devices can automatically stop a train in an emergency, even when the conductor can't.

Hwang says new fare hikes that have been proposed should be used to install that technology on Metro-North.

The federal government mandated the use of positive train control technology on all commuter railways by 2015, but extended that deadline to 2018 when many railroads said they could not meet it.
