I have a few questions;
- Does the system inherently eliminate track circuits?
- Are axle counters used even as train detectors over switches and crossings (eg Millswood loop)?
- Will the whole Seaford line be changed to axle counters as part of electrification?
- If track circuits are being retained between Goodwood and Noarlunga Centre what steps are being taken to allow for traction return currents (impedance bonds and the like)?
