Lionel made the 208 toolbox with tools from 1934 to 1942. It came in sets with the 400E work train, and was available separately. The 812, and 2812 O gauge gondolas came with the tools but without the box when the gondola was part of a work train.
Work trains were a steam engine, tender, crane, gondola, searchlight car, and caboose. Standard gauge work trains were always pulled by the 400E and had 200 series freights. O gauge work trains were pulled by the 260E, the 263E, the 226E, and the 763E.
The tools are nickel plated cast iron, and each measures about 4 inches long. The metal tool boxes come in aluminum as shown above and gray. I’ll add a picture of a gray toolbox in the future.
