British Engineering Standards Association Standard Goodgs six-coupled freight engine. The standard Belpaire boiler came in two sizes -- this was the larger one. The earlier version was designed for the permitted axle loads at the time. When much of the system was upgraded with heavier rail and permanent way, the BESA standard now used a larger boiler as shown in the specs. The boiler was used with 2-6-4T and 4-4-0 designs as well (which see). See the HP 4-6-0 for full description of the BESA intention and varying views of its utility.
