I remember years ago working in the asbestos industry and learning how polluted the outside air is in cities from asbestos from automotive brakes being worn down.

Milwaukee Road – Little Joes Locomotives

Milwaukee Road – Little Joes Locomotives

"The unique "Little Joe" electric locomotives were built by General Electric in 1946 to fill an order placed by the Soviet Railways to operate on a 3,300 volt, DC system. However, upon the order being completed relations had broken down between the United States and Russia (thus plunging us into the Cold War) and the locomotives had no place to go, with all 20 sitting at GE’s Erie, Pennsylvania plant awaiting purchase. The "Little Joes" derived their name from the Soviet Union’s ruler, Joseph Stalin originally being called Little Joe Stalin's locomotives and later shortened to just Little Joes. From a technical standpoint these motors carried a 2-D+D-2 wheel arrangement, were equipped with eight GE 750 motors, and operated on a 3,000 volt DC system (perfect for the Milwaukee Road) with a continuous rating of 5,500 horsepower! While geared rather low with a maximum speed of just 68 mph they produced 75,700 pounds of tractive effort and would prove to be perfect in stiff, mountainous territory."
