Maintaining Rail Safety on the Down Relief Line

Yet another productive shift for the Amaro team on Tuesday, delivering essential support works on the Down Relief line at West Ealing, forming part of the ongoing P2R/Brunel project.

Facilitating the recovery of an Insulated Rail Joint (IRJ), our team removed, refitted and tested a Frauscher RSR123 wheel sensor. Big thanks to Ashley Jones, who took on the SMTH testing, and to Niamet Shah for carrying out the installation works.

Left in situ and bonded out during the Crossrail project, after being left in place for many years, IRJs can become potential rail defects and end up needing additional ultrasonic testing. Which is exactly why their safe removal is such an important part of maintaining long-term reliability.

What do axle counters / wheel sensors do?

– They detect trains by counting axles entering and leaving a track section. If the counts match, the section is clear. If not, it’s occupied.

– Unlike traditional track circuits, axle counters don’t rely on rail conductivity and are often seen as a more reliable, lower-maintenance alternative.

… removing the need for IRJs and similar equipment in the process.

All in all, a solid night’s work and another example of the Amaro team delivering safely, efficiently and collaboratively.

Great work from everyone involved.
