The B&A began to increase the speed of its freight service in the early 1920s and gradually took the 2-10-2s out of service because they were too slow. In 1926, they were transferred to the CCC&StL and later they went to the NYC&HR. In 1928 all ten of the Class Z-1 locomotives were sold to the Canadian National Railway.
There are no surviving B&A "Santa Fe" 2-10-2 type locomotives.

| Z-1 | 10 | 1100-1109 | 1919 | ALCO | USRA allocated .Santa Fe-Light. locomotives. Sold to the Canadian National Railway in 1928 and became CNR numbers 4200-4209 |
Data from the 1953 Canadian National locomotive diagram supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Works numbers were 60065-60074 in January 1919.
The origin of the data for this class reflect its bifurcated career. They began as USRA Light Santa Fes (Locobase 231) assigned to the drag freights on the B&A. Very soon after their introduction, however, the B&A made a particular effort to increase freight-train speeds and these engines proved ill-suited to such work. They went to the Big Four in 1926 and the New York Central itself in 1927.
In 1928, the Canadian National bought the class, renumbered them 4200-4209, and placed them in their own class T3 to serve the Grand Trunk. There they found a home and served their new owners until the end of steam. The first of the class retired in 1955, the last in 1961.
