The LSWR 380 class was a class of 4-4-0 tender locomotives designed by William Adams for the London and South Western Railway and introduced about 1879. They were built by Beyer, Peacock and Company and received LSWR numbers 380-391. They were nicknamed "steam rollers" because of their small solid bogie wheels. The design was developed from Adams' 46 class 4-4-0T, later rebuilt as 4-4-2T.
