These large 24½-ton open wagons were intended to be the standard bulk coal wagons under the BR ideal stock plan, being the heaviest 2-axle wagons which could be granted near-universal route clearance. Where clearance wasn't available however was under the screens of many collieries. While the slightly lower 21-ton wagons proliferated this 24½ type was built in limited numbers and frequently made a nuisance of themselves by getting mixed in with the 21-tonners when going somewhere they wouldn't fit!
