Yes there is also a close connection between the early South Australian
3ft 6in gauge and the Norwegian 3ft 6in gauge, and I intend to cover
that in the book. As things developed the South Australian 3ft 6in gauge
more closely resembled the Norwegian than did the Queensland.
Norway's Beyer, Peacock 2-4-0Ts with the sloping cylinders were an
extremely important development, as they greatly surpassed the previous
attempts at building 3ft 6in gauge locos in performance. They appear to
have been jointly designed by Carl Pihl (of Norway) and Charles Beyer.
The first was "Tryggve" BP builder's number 704 of June 1866, so they
predated the Isle of Man copies by a considerable time. Yes the SAR "V"
class derived from the Norwegian Type VI, but they were much smaller
than the Norwegian locos.
The early sequence of 3ft 6in gauge developments (as I see it) were:
1. 1862 - Hamar-Grundsett (Norway) railway opened - proved 3ft 6in gauge
would work for a public railway. Used link and pin couplings, and 0-4-2T
locomotives built by Robert Stephenson which had a rigid wheelbase and
recommended minimum curve radius of 15 chains.
2. 1864 - Trondheim-Støren (Norway) railway opened - proved 3ft 6in
gauge would work in difficult country. Still used link and pin
couplings, but locomotives were Avonside 2-4-0Ts with leading Bissell
truck, and much more successful on sharp curves (but the sharpest was 9
3. 1865 - 1867 Ipswich - Toowoomba railway opened - proved that 3ft 6in
gauge would work in mountainous country with very sharp curves (5 chains
radius). First locomotives were Avonside 2-4-0s - a tender version of
the locomotives already supplied to Norway. Did not use chopper
couplings as they had not been invented yet, and the English consultant
Charles Fox did not like the link and pin couplings.
4. 1866 - 1868 Drammen - Randsfjord (Norway) railway opened. First use
of chopper couplings, and first use of Beyer, Peacock sloping cylindered
2-4-0T locomotives. Both of these new developments were considered very
After that a frenzy of 3ft 6in gauge developments occurred throughout
It perplexes me why Queensland avoided using Beyer, Peacock locomotives
when they were used so successfully in all the other Australian
colonies. Possibly politicians or book-keepers made the decisions based
on lowest tender bids rather than long term cost effectiveness
