Ugly 62 that runs along the Spa Valley line. That every engine created has a name and number is not surprising.
Each locomotive had its owner, UGLY's being Robert Stephenson & Hawthorns Ltd. and each had a log of activities that was kept by its operators, a partnership that once brought wealth. The above website link has details in the Engines and Carriages on their side bar.
Of greater interest to me was a company's logo, S.& L. MINERALS Ltd. secured along with the number 62 on the side of UGLY. It has a historical significance that dates back to King George lll and Cape Breton County, Nova Scotia and the W.Sydney and Loiuburg Railway, once the finest in all the world.
P.S. There are various videos for any of you who are train buffs on You Tube.
