#DidYouKnow? As part of the #DowntownRailReconstruction project, RTD uses ultrasonic testing to keep our rail system safe and reliable. 🚆✨

Here’s how it works:
🎧 A transducer sends high-frequency sound waves into the rail.
📡 Those waves bounce back to a receiver, where a certified technician analyzes them on screen.
⚙️ The reflections reveal the location, size and type of any internal defects — all without damaging the rail.

It’s one more way RTD is using advanced technology to ensure a safe, smooth ride for our customers.
