This group of model train components consists of various O gauge pieces manufactured by Lionel. The collection includes a black streamlined steam locomotive featuring a 2-4-2 wheel arrangement, a decorative red and silver horizontal stripe, and the number 6 visible on the side. Accompanying the engine is a black coal tender with a rivet-patterned body and an embossed side panel reading LIONEL LINES. The set includes several tinplate passenger cars finished in green with yellow window inserts and trim. Two of these cars are marked with the number 2640 and labeled PULLMAN, while another is an observation car numbered 2641 with an integrated rear platform and railing. Additionally, there is a red freight gondola car. Materials include pressed tinplate and die-cast metal components. The items feature mechanical latch-style couplers characteristic of pre-war production.
