Co‑acting signals
If it is possible for a running signal to be obscured from a Driver’s or Track Vehicle Operator’s view, a co-acting signal may be used to provide information about the running signal indication.
Co-acting signals may have:
- a sign showing CO‑ACTING, INDICATOR, or an abbreviation
- a signal identification sign with the same details as those on the primary signal.
