Inscription. In 1923, the Great Northern Railway received 28 Class P-2 “Mountains” from the Baldwin Locomotive Works. These locomotives were assigned numbers 2500 through 2527 and had 29 X 28 cylinder, 73” drivers, a 200 psi boiler pressure, a tractive effort of 54,823 lbs and weighed 365,600 pounds each. Later, the boiler pressure was raised to 210 psi which increased the tractive effort to 57,580 pounds. The Class P-2 “Mountains” did an excellent job in passenger service. They were eventually replaced by the S-2 Northerns in Empire Builder service. The P-2 Class locomotives were then used in freight service and were retired in 1955.
