| 1. | Among the upgrades are axle counters, mounting of an tracks.
|
| 2. | Axle counter assemblies can be bolted or clamped to the rail.
|
| 3. | Axle counters do not directly detect trains in between the paired sensors.
|
| 4. | The load cells can also be used as a rudimentary axle counter.
|
| 5. | Axle counters are particularly useful on electrified railways as they eliminate traction bonding and impedance bonds.
|
| 6. | Axle counters are also useful on long sections where several intermediate track circuits may be saved.
|
| 7. | Track circuits in the tunnel had problems because of wetness; in 2015 these were replaced with axle counters.
|
| 8. | Axle counters can be used in conjunction with the WIPD " ! device to correlate the faulty wheel with the train axle counter.
|
| 9. | Axle counters can be used in conjunction with the WIPD " ! device to correlate the faulty wheel with the train axle counter.
|
| 10. | Axle counters require no bonding and less cabling in comparison to track circuits, and are therefore generally less expensive to install and maintain.
