7714 is a GWR Collett 5700 class 0-6-0PT ‘pannier tank’, one of two examples on the SVR (the other being [[GWR Pannier 5764 | 5764]]). The 5700 class was the largest most numerous class of engine designed and built by the Great Western Railway; more than 860 were built between 1929 and 1950. Pannier tanks could be found at work all over the former GWR system and although designed primarily for shunting duties, they were regularly used on local freight and passenger workings. The class was rated 3F<ref>Classic British Steam Locomotives (ISBN 1-86147-138-6)</ref> by British Railways, although some publications record it as 4F.<ref>Keith Langston, ''Scottish Steam: A Celebration'' via [https://books.google.co.uk/books?id=mPNsBQAAQBAJ&lpg=PT337&ots=b3UyIbOWvR&dq=5700%20AND%204F&pg=PT337#v=onepage&q=5700%20AND%204F&f=false Google Books] (retrieved 27 December 2016)</ref>
