HR2884S Rivarossi Heavy steam locomotive, class 4000 “Big Boy”,of the Union Pacific - Sound

Novelty 2022 - Heavy freight train steam locomotive, class 4000 “Big Boy”Heritage Edition (with fuel tender),of the Union Pacific with Sound

Running number: 4014

Called “Big Boy” as of all the articulated engines, this 4-8-8-4 was the biggest in terms of size, weight and speed. The name originates from a message written in chalk on the door of the smoke box by a worker on the prototype project. “Big Boy” can reach speeds of 80 miles per hour, with over 7000 hp.

With a confounding length of 475mm (almost 19 inches), a 5-pole motor and brass flywheel, a DCC Ready 21-pin plug, handrails made from steel wire and much more, this locomotive is unlike any other and undeniably lines alongside other models as a classic.

Special edition in celebration of the 150th anniversary of the first transcontinental railroad and  60 years since the “Big Boy” locomotives first started being removed from the US network.
