Tom's Pacific

Chicago & Northwestern Class E Pacific

The C&NW began life as the Chicago and Galena Union Railroad in 1848.  The panic in 1857 resulted in a reorganization into the Chicago & Northwestern Railway Company in 1859.  Meanwhile, trackage for the Chicago, St. Paul, Minneapolis, and Omaha Railroad began being laid in 1865.  The Omaha was formally acquired by the C&NW in 1882.  The C&NW's Proviso yard (13 miles west of the Chicago Loop) was completed in 1929.  At time of completion, it was the largest freight yard in the US with a capacity of 26,000 freight cars.   The C&NW was absorbed by the Union Pacific in 1995.

The C&NW ran both light and heavy Pacifics.  The Chicago & Northwestern Pacifics were built primarily by Schenectady.

Class E2 Pacifics

The heavy Pacifics were given the class designation E2.   In 1934 a number class members were upgraded to Scullion 79" drivers and cast cylinders.  They were converted to oil burning and had boiler pressure increased from 210 pounds to 225 pounds.  The other members of the class received similar treatment in 1935 but remained coal burners.  Oil burners were class E2A and coal burners E2B.  One source says that the oil burners were returned to coal burning in 1939, while other sources say 1946.  Whatever was the case, eventually the whole class did return to coal burning and reverted to simple class E2.
