G&SWR 99 Class

The Glasgow and South Western Railway (GSWR) 99 class was a class of four 0-2-2-0 steam locomotives designed in 1855.

Development
Four examples of class designed by Patrick Stirling were built for the GSWR by R and W Hawthorn between April and August 1855. Little is known about the class which is variously described as having a "dummy crank" or a "crank axle."

Withdrawal
The members of the class were apparently not successful, and all were withdrawn by James Stirling during 1866 and 1867.
