Lionel Lines LionMaster J3A Hudson #1900 Considered by many to be among the most beautiful and successful steam locomotives of all time, the J3 Hudson was the ultimate development of this pioneering locomotive on the New York Central. Back for the first time in many years, the LionMaster J3 is now available for the first time with our LionChief+2.0 control and sounds. This 4-6-4 locomotive packs in the detail of a larger sized locomotive, with the convenience of being able to navigate tighter curves for O-gauge layouts.
