Drudge Retort: The Other Side of the News

Electronic Controlled Pneumatic (ECP) brakes use electronic signals to control the application and release of brakes on a train, which is a significant improvement over traditional air brakes. This technology allows the brakes on each car of the train to be applied more uniformly, reducing the risk of uneven braking that can lead to derailments. When trains carrying hazardous materials derail, there is a risk of spills or releases that can pose a threat to public health and the environment. The use of ECP brakes can help reduce the risk of these types of incidents, as well as the severity of any spills that do occur. By rescinding the rule requiring the use of ECP brakes on trains carrying certain hazardous materials, the Trump administration potentially increased the risk of derailments involving these materials.

This could have several potential causes, such as increased stopping distances due to the lack of ECP brakes or increased stress on the mechanical components of the traditional air brakes used instead.

Ultimately, the impact of this policy change on the safety of trains carrying hazardous materials would depend on several factors, including the specific types of hazardous materials being transported, the routes being used, and the other safety measures in place. However, it is clear that the use of ECP brakes could have helped mitigate the risks associated with these types of shipments, and the lack of these brakes could potentially increase the risk of derailments and other incidents.

Trump allowed industry to take us back to the 1960s and industry did so; consequences be damned.

This is so not true... Maosy told me it was Hunter's Laptop's Fault.

Washington Post.

We decided to examine every possible regulatory change made under Trump that could be related to the accident and assess whether it could have made an impact. A preliminary report by the National Transportation Safety Board, which is investigating the incident, said the Norfolk Southern crew received an alert about an overheated wheel bearing and was trying to slow the train before it came off the tracks. From our analysis, none of the regulatory changes made during the Trump administration at this point can be cited as contributing to the accident.

Slurp, gobble it down and choke on it.

Light reading from the GAO on the ECP debate: DOT's Rulemaking on Electronically Controlled Pneumatic Brakes Could Benefit from Additional Data and Transparency

A bit early the slurping and gobbling lest you be the one slurping and gobbling in the end.

"Preliminary Report" - The why here is important.

From the WaPo Article: The train was not equipped with ECP brakes; instead its locomotive used dynamic braking " electric traction motors acting as generators, which slow the train and dissipate mechanical energy as heat. When the crew received the alert about the overheated wheel bearing and engaged the dynamic brake, an automatic emergency brake application kicked in to stop the train, the NTSB said. That's a full application of a train's main air brakes that takes place when the train senses that air-brake hoses between rail cars have been disconnected " indicating the train had already derailed.

The why being is it seems the train was in the process of derailing when the alert reached the engine or the train's dynamic braking system actually triggered the derailment. A full article is here: Washington Post and it goes through regulation by regulation the "preliminary" impact. It also explains my GAO link.

And we don't know what they will find about the DOT much like what they found out about the FAA and Boeing. DOT too cozy with the railways? If you even skim what I posted above from the GAO this rail system was one of the first to pull out of the ECP braking system program despite wavers. I think the above article may hint at why we are not seeing these regulations brought back as well. Just the reading I have done though seems to indicate ECP is the right thing to do.

Side note: I get stuck waiting for Dow trains from time to time. Let me just say that is not my favorite thing to do for many reasons including the poorly maintained tracks and trains - essentially waiting for just what happened in Ohio. I knew someone who lived a few houses down from the big derailment we had here in the 80s. That wasn't good either. Made the national news at the time.
