Maurie,

The CTC starts at Mile End Loop (for South Line), Trans Adelaide Control
controls intermediate Absolutes NR 2 and NR4 that protect Goodwood Junction,
in the event of a failure the ARTC Controller issues a Train Order for the
Mile End - Belair section. In the body of that order in addition to the
instructions to proceed will be the message: "ON ARRIVAL AT NR2 (or) NR4
(which ever is appropriate) CONTACT TRANS ADELAIDE CONTROL." The Trans
Adelaide Controller will then issue a Verbal Caution Order for the Driver to
pass that signal.
