The Lionel Illinois Central F-3 No. 2363C B Unit was produced in 1955 and 1956. Unlike the A Unit No. 2363P of this engine that was produced on a GRAY body shell, the B Unit used an ORANGE body shell. A rubber-stamp was used to apply the lettering and stripes. Reproduction shells have silk-screened application of this lettering and colors. The chassis is BLACK, as are the truck side frames.
This version has louvered roof vents, filled in portholes, cast in side ladders, and solid die-cast metal non-operating couplers at each end.
