Railroad cars can stay in service longer, even with leaky shock absorbers
What happened
US rail regulators are making it easier for freight cars to stay on the tracks longer. They will now allow cars with leaky shock absorbers to remain in service, as long as a sensor shows the unit is still working.
Why it matters
This change means freight rail operators can avoid costly repairs or replacements for a common issue. Previously, any visible oil leak from a car's cushioning unit meant it had to be taken out of service. Now, if a sensor confirms the unit is still functional, the leak is no longer a mandatory repair.
The signal
Watch for how quickly freight rail companies adopt the new sensor technology and how many cars remain in service that would have previously been pulled for maintenance.
