Wabash class J-2

United States 1916 23 produced
No. 690 in October 1936 double-headed in front of another locomotive Edward Lindquist / collection Taylor Rush

In 1912, the Wabash had procured the last new passenger locomotives with the 16 class J-1 Pacifics. In 1916, a class G-1 locomotive with a 2-6-2 wheel arrangement was taken instead and converted into a 4-6-2. The G-2 was particularly suitable because it already had 70-inch wheels and was less than ten years old. The locomotive was lengthened by about four feet and the leading axle was replaced with a bogie. 

Since the conversion was successful, another 22 of the total of 60 engines of the G-1 class were converted in this form. Some of these had received the numbers between 1676 and 1681 and were used between New York and Ontario, the others carried the numbers from 683 to 699 and remained entirely in the USA. The first of these was retired in January 1947 and the last in February 1952.
