Thirty-nine of these relatively small but handsome Class
J-3-a Pacifics were delivered to the Grand Trunk Western Railroad over a two-year period, #100-#118 from the Baldwin Locomotive Works and #5030-#5050 from the Montreal Locomotive Works in 1912. At least twenty-
three, including #5030, were later equipped with new boilers with substantial changes, including a 24% reduction in the small tube count from one hundred and eighty-one to one hundred and thirty-nine. Installation of 50 sq ft of thermic syphons also increased the firebox heating surface to 231 sq ft. The grate is 50.62 sq ft and total heating surface is 3,003 sq ft including 578 sq ft superheating.
#5030's driver wheelbase is 13’ 4” and engine wheelbase 33’ 2”. It weighs 226,000 lbs, 146,550 lbs on the 69” drivers. With 23” x 28” cylinders and operating at a boiler pressure of 190 psi, It delivered 34,669 lbs tractive effort. #5030’s tender weighs 150,000 lbs light and has a capacity of 9,000 gallons of water and 12 tons of coal.
