Acoustic Ultrasound in Railroad

Keeping railcars and locomotives moving is as important to an economy as any industry. CTRL Systems has worked closely with railroad service organizations, operators, and manufacturers to identify more than 20 areas of application to use the UL101 and InCTRL for inbound/outbound inspection stations.


Manufacturers of hopper cars and train compartments that carry grain, cement, or other granular materials must inspect their products for leaks in order to ensure effective transportation. The current industry standard is extremely rudimentary, typically only done visually with a flashlight. This practice is very time consuming, and still leads to routine leaks and loss of inventory. However, CTRL revolutionizes this process with the UL101 ultrasound listening devices.
