English: General Motors advertisement for its new line of Winton diesel engines. Union Pacific's M-10001, shown in the ad, was the first train to be equipped with the new version. Seller dates this as 1935; the train was delivered to the railroad in late 1934, when it set the record from Los Angeles to New York. However, it did not enter regular service until May 1935 as the City of Portland, following some rebuilding at Pullman. With this close-up, the many rivets that held the aluminum train together can be seen, making it much different from the Budd Company's stainless steel, shot-welded Zephyr streamliners for the Burlington.
