“This set is a nice addition to any LEGO train collection. It has some cool stuff like a little shed, a cart, a palette with weight, a wagon and the crane. The set is a great build and we also get a few stickers to worry about. The wagon can be attached to the wagon with the... More crane very easily and there's also space for the cart and the shed. The crane swivels full 360° and the cockpit can be opened very easily.”

“The 4552 Rail Crane is the latest installment in a long history of rail crane sets made by The LEGO Group for their train system. There have been at least two other models, 7817 and 7814, and all are basically double-bogied flatbeds with a crane for lifting rail, pallets and... More other cargo around. The 4552 has a midsized flatbed, a bit shorter than its predecessors, as well as a second flatbed car for holding cargo.”
