Temporary Arrangements The S & I diagram refers to the Temporary Signalling & Interlocking Arrangements. I assume that these were related to the construction of the new Wellington yard and the Tawa deviation. There were a number of S & I circulars for Lambton covering the period from the 1920s until the new Wellington Station was opened in 1937.
Link To Lambton Yard At the south end of the Thorndon Yard there was a link to the Lambton Yard. In later years it ran from the Goods Yard. I do not know where it ran from in 1928.
Colour Lights The Regulations for Three-position Upper Quadrant and Colour-light Signals applied. I do not know when the colour light signals were installed.
Crossover No 4 at the north end was power worked.
Cross-over To Exchange Sidings I do not know when the crossover from the Johnsonville Line to the Exchange Sidings was installed.
Stop Signal Thorndon - Palmerston North was tablet territory and so the running signals are classified Home or Starter. Of interest is signal 36 which is classed as a Stop signal.

Enginemen must first give the whistle for the road they are on, and then the whistle for the road they require.
Note: - To avoid unnecessary whistling, enginemen or shunters should, when near the signal-box, tell the signalman what road they require.
