This locomotive replaced the No. 681 in 1954, and was available for one more year. It was produced on a BLACK painted die-cast boiler with WHITE heat-stamped numbers. This locomotive has the running boards painted WHITE on both sides. There is a "6200" keystone decal on the front.
Unlike previous editions of this locomotive, this version boasted the addition of valve gear linkage that was attached to the first driving wheel. A three position directional unit controls the motor that powers the four driving axles that utilize Magnatraction. There is a smoke unit and a lighted headlight lens in front. Came with No. 2046W-50 Pennsylvania streamlined tender that housed a whistle. The tender was equipped with bar-end trucks that has one magnetic coupler. There are no variations.
This, and other versions of the S-2 locomotive were produced by Lionel for both O and O27 Gauge sets. However, because of length of the eight driving wheels these locomotives run best on the larger diameter O Gauge track.
