[Invicta]

QUOTE (5696Arethusa @ 19 Dec 2007, 10:55) <{POST_SNAPBACK}>On the steam front I can't think of a smaller class having been produced than the Princess Royals with only 12 (not counting the Turbomotive) though this class has the benifit of long service, toplink duties and a wealth of liveries.

The Triang/Hornby Caledonian single was a class of one- it does share the same advantages of the Princess though- long service (1886-1935), toplink duties and 3 livery choices
