It's been more than a month since the toxic train derailment that Dominated headlines across the nation. On Monday, Norfolk Southern announced a new safety plan that might prevent disaster in the future.

That plan includes adding 200 hot bearing detectors to the networks, 13 new detectors to high traffic routes, cameras on their rail network, re-evaluations to the temperature that triggers the alarms and partnering with Georgia Tech Research Institute to develop new inspection technologies.

Some officials tell 21 News it's a step in the right direction, but that it's not quite enough.

"That's a good step forward, I mean you've got to start somewhere," said Johnny Long, American Rail System Federation Chair. "Members - or not just members but the union and the railroads need to come together and sit down and talk about these things, how we can get to the railroads being safer," he said.

Others officials tell 21 News Norfolk Southern is way behind and now, they're looking for safety requirements in law.

"Too little too late," said Tim Burga, Ohio AFL-CIO President. "The house bill here in Ohio is an approach. There's also a proposal introduced in the US Senate that would codify some of the things Norfolk Southern is saying they now will do, and it goes even much further than that," he said.

Although Norfolk Southern plans to re-evaluate that temperature that triggers the alarms, when 21 News asked if they would lower the temperature standard for what's considered critical, we never received an answer.
