The Lionel Hudson Type 4-6-4 Locomotive No. 2046 boiler is derived from a modification of the No. 726 Berkshire locomotive and it shares this same boiler with No. 646 and No. 2056. It was available in 1950, and 1951, and again in 1953. This locomotive was replaced in 1952 by the No. 2056 which does not have Magne-traction. This engine was equipped with Magne-traction, smoke, drive rod connecting rod valve gear, three position direction unit that is adjustable from the top of the boiler, and there is a whistle in the tender. It came with both rubber and heat-stamped numbering on the cab.
