You may correct me if i'm wrong but 3 position signals were brought in under
circular C.8/15 Sept 1915 I am not sure when they were first used but I believe it
could have been between Richmond and Sth Yarra in Oct 1915.     The 1919 book of
Rules and Regs in clause 56 shows the rules regarding 3 position signals as speed
signaling. Was the description  not copied from the R .S .A Principles of Signal
Indication (1906) and Signaling Practice As Defined (R.S.A 1913) Incorporated  in
the report of the committee on Transportation of The American Railway Association
May 1911.
