The Lionel Prairie Type 2-6-2-Locomotive No. 2026 was issued on two different occasions by Lionel. This accounts for the two variations of this locomotive. This engine has a boiler whose casting was derived from the No. 1666 and altered by adding a feed water heater box on the pilot and extending the sand dome. First issued in 1948 and 1949, this version (Variation A) would be a Prairie Type with a 2-6-2 wheel arrangement. It came with sliding shoe center rail pickups, a smoke unit, and a three position directional unit whose control lever protrudes from the top of the boiler right in front of the cab. It was equipped with a eccentric crank driving rods and steel rimmed driving wheels. The tender was the No. 6466WX that had handrails on the deck, staple-end trucks with one electronic coupler.

The second variation (B) was issued during the Korean War between 1951 and 1953. For this version Lionel would change the trailing truck into a four wheeled sheet metal version that would alter the type of locomotive to a 2-6-4 Adriatic. Other changes resulted in the removal of the eccentric crank and the steel rims on the driving wheels. It came with roller center rail pickups and either a No. 6466W, No. 6466T, or a No. 6066T tender that had bar-end trucks with one magnetic coupler.

Neither of these variations have Magnetraction.
