Arnim Zola used a train for transporting equipment to and from HYDRA bases. He had special access to communications in the locomotive. The train was mainly used to transport him and the super HYDRA soldiers to various HYDRA bases around Europe. The locomotive was powered by the Tesseract, like Zola's other inventions. Due to its power source and advanced design, it was able to reach far greater speeds than any other locomotive of that era.
In early 1945, Captain America, Bucky Barnes and Gabe Jones conducted a raid on the train. During the attack Bucky fell from the train into an icy ravine. However, Zola was still captured soon after.
