what is it?
The M-10000 was an early American streamlined passenger trainset that operated for the Union Pacific Railroad from 1934 until 1941. M-10000 was the first streamlined passenger train to be delivered in the United States, and the second to enter regular service after the Pioneer Zephyr of the Chicago, Burlington and Quincy Railroad. Rather than having a locomotive and separate detachable cars, the M-10000 featured a front power car with connected passenger cars.
