Geared steam locomotive
A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
North Bay Railway
The four Diesel-Hydraulic locomotives are of common vintage and were constructed in the same works. The first two belong to Scarborough Borough Council, have operated on the North Bay Railway since construction, and are currently leased to the operating company. The other two locomotives are directly owned by the operating company and were originally built for the Golden Acre Park in Leeds. After its closure they were also used at Morecambe, Kilverstone and Great Woburn Safari Park. They were moved to the Cleethorpes Coast Light Railway for storage before finally being relocated to Scarborough in December 2006. In 2016 "Georgina", the railway's first ever steam locomotive, was finally completed and entered revenue earning service over the Easter holiday. She has proved to be very popular, with the crews and public alike, and is easily capable of hauling a loaded, five coach, train up the steep hill, to Scalby Mills station.
