The 14xx class is a class of small Great Western Railway Tank Locomotives intended as a lightweight locomotive for branchline work. They were reported to not be very popular locomotives on the Bala branch.
The 58xx class is included here as they were similar to the 14xx class but were not equipped for working autotrains.
