Etna (5 Gauge)

Overview
Etna is a 4-4-0 Tender locomotive designed by Don Young. It was based on the LNWR Whale Precursor Class. At just over 5 foot in length it is relatively compact for a 5" Tender locomotive, with 1.75" diameter cylinders and a driving wheel diameter of 7.187". Don Young passed away before the design had been fully covered in "Engineering in Miniature", however the drawing set had been completed and marketed prior to publication.
