A Study on Interference between High Voltage Impulse Track Circuit …
WebWe also use high voltage impulse (such as in the video) and frequency based UM71 track circuits as well as a lot of axle counters. Its a casserole I know. In new installs/ upgrades over the last 10 years it's been UM71s and axle counters. 2. Some of our track circuits are 10m long and some axle counter sections may have kms between them.
