Brainerd & Northern / Nickel Plate / Minnesota & International / St Paul & Duluth / Northern Pacific 2-6-0 "Mogul" Type Locomotives

Data from 1899 Brooks Catalogue.

Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004.

Works #1629-1633 in March 1890. Rumary-Lambert credit the class with 19" cylinders, which they may have received some time after their initial delivery.

Low-drivered light Mogul for the Nickel Plate, as the New York, Chicago, and St. Louis was known. The class was renumbered in 1910 with retirements beginning only a few years later in 1913 (2). Two more were withdrawn in 1914 and 219 was scrapped in June 1916.

Class D (Locobase 809)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004) and from a 1944 Northern Pacific Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Class D-1 (Locobase 808)

Converted relatively quickly (by 1887) to 0-6-0 switchers with 14' 2" wheelbases.

Class D-10 (Locobase 8150)

Data from NP to 1944 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

The "Mike & Ike" (formerly the Brainerd & Northern) was incorporated in 1900 (July 17). It was also known as the Sportsman's Route and ran from Minneapolis to International Falls. It was not actually absorbed by the NP until 1941.

Class D-2 (Locobase 810)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004).

Class D-3 (Locobase 811)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004).

Class D-5 (Locobase 807)

Rebuilt as cross-compounds in 1897 R.H. 30 x 24, LH 19 x 24. Specifications refer to that version.

404-409, 430-432 built at Brainerd; 410-418,426-432 at Schenectady. 430-432 rebuilt by Schenectady in 1897 as simple-expansion locomotives with two 18" x 24" cylinders.

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004).

Class D-6 (Locobase 812)

400-401 (works #4842-4843), 402-403 (5432-5433) built in 1899, slightly lighter on the drivers at 111,000 lb, engine weight was 130,100 lb.

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004).

Class D-7 (Locobase 8146)

Data from NP to 1944 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

The tender shown is likely from a later era when these Moguls were used as switchers. The B & N later was renamed the Minnesota & International. Connolly's list of all Baldwin locomotives tells us that the Josephine came first, in August 1892 as works #12890. The James B Ransome followed 2 months later (works #12957)

Class D-8 (Locobase 8147)

Data from NP to 1944 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Class D-9 - compound (Locobase 8148)

Data from NP to 1944 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Richmond delivered the 8 engines in this class over a 5-year period in batches of 2 each in 1898 (works #2722-2723), 1899 (2829-2830), 1900 (3122-3123, and 1902. At least one of these two-cylinder cross-compounds was converted to simple expansion in 1905; see Locobase 8149.

Class D-9 - simple (Locobase 8149)

Data from NP to 1944 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Apart from the unusual choice of a 17" diameter for the cylinders, this was a typical and straightforward alteration of the 2-cylinder compound D-9 design that had arrived on the M & I in 1898 (see Locobase 8148).

Class F-7 (Locobase 6716)

Data from TStL&W 1 - 1924 Locomotive Database supplied in May 2005 by Allen Stanley from his extensive collection.

Drury (1993) tells us that these Moguls were originally procured by the Nickel Plate. The 1924 Clover Leaf book suggests that the NKP moved to this lighter-weight line to augment the F-6 Moguls already there.
