The Prairie Type 2-6-2 Locomotive No. 2025 was based on the Pennsylvania Railroad’s Class K-4 Pacific locomotive. However, Lionel left off one of the leading truck axles that was on the prototype, which is why their version of this locomotive is classed as a "Prairie." Lionel would not produce a 4-6-2 Pacific locomotive during the post-war years. This locomotive did not have Magnetraction and early versions of this locomotive came with "Baldwin Discs" that had nickel rims for the driving wheels. These wheels have the "Baldwin" name embossed on them. It has a three position direction unit whose lever is adjustable from the top of the boiler and is located behind the smoke stack. This has a No.6466WX tender that had rear deck handrails and staple-end trucks with a magnetic coupler and a whistle. Although the four digit number of this engine designates it for use with O27 track, it will also run on O radius curves. This locomotive has a redesigned pilot with a simulated front coupler and has a BLACK smoke stack that is considerable smaller than the SILVER aluminum ones.
