The boiler itself had a heating surface of 722 square feet while the firebox added another 80 square feet to give a total heating surface of 802 square feet. The grate area pf the firebox is 13.1 square feet. In working order, the engine unit weighs 32T 1C (32564kg), the tender 24T 5C (24629kg) which gives a total of 56T 6C (57203kg).
