Class Details by Steve Llanso

Class 10 / C-26 (Locobase 863)

Data from 1944 Northern Pacific Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 2206 and 2210.

Like the smaller LS & M engines 8 and 9 (Locobase 864), this pair kept its road numbers when the railroad became the St. Paul & Duluth in 1877.

1035 was sold in May 1901, 1036 in August 1901 to the Northern Pacific as part of the latter's takeover of the St P & D.

Class A-1 (Locobase 9298)

Data from CStPM&O 4 - 1900 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Baldwin works numbers ran in a broken series from 2660 to 2793 and were produced in January-May 1872. Two more (works #2811, 2822) went to the St Paul & Duluth; see Locobase 865.

That the information comes from an Omaha Road diagram book indicates that these engines had a varied career. They were the first large class of locomotives delivered to the Northern Pacific and at the time of their arrival, they had drivers measuring 56 1/2" in diameter.

Four went almost immediately to the Chicago, Milwaukee & St Paul as 204-208 (works #2661, 2669, 2671, 2673) as did 5 others to unrecorded owners. Others were sold off in 1877 (to the Minneapolis & St Louis), and still others in 1880. Most of the rest were retired in the late 1890s or sold. The one that came to the Omaha Road in 1892 had received 63 1/2" drivers at some point and that is shown in the specifications.

Class B-1 (Locobase 887)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004). Works numbers were 10247 and 10252 in September 1889.

Other than weighing slightly more and arriving 2 years later, the B-1 Eight-wheelers were duplicates of the Bs (Locobase 878) that had been produced in 1887. The W & CR evolved into the Washington Central in 1898 and was absorbed by the Northern Pacific in July 1907. 673 was scrapped in February 1924 while 672 lasted until March 1931.

Class B-2 (Locobase 855)

The only works numbers Locobase can identify as possibly belonging to this subclass were 2490-2491 in July 1871; 4891-4892,4897, 4900 in December 1879.

309 was sold in April 1906 to the Pensacola, Alabama & Tennessee.

Class B-2 (Locobase 856)

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

Locobase wonders if these might have been numbered 251-254 instead, because a list supplied by Allen Stanley

Class B-2 (Locobase 879)

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

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class B-2 / B (Locobase 878)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004) and NP 1 -1929 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 8560-8562, 8565-8572 in May 1887 and 8668, 8672-8673, 8677-8678, 8680, 8682-8684, 8688-8689 in July.

Most served all of their time on the NP proper before being scrapped; this final event occurred over a decade and more from 1925 to 1940 with a few being retained through World War II. Some were sold to other, smaller Northwest or Minnesota railroads.

670 went first, being sold to the Canadian Northern in 1901

Minnesota & International bought 4 engines: 655 and 658 in July 1909, 6511 in January 1911, and 668 in June 1913. These were renumbered 21, 22, 19, and 20, respectively.

652 went to the Big Fork & International Falls in August 1911 and bore the number 1. The BF & IF was sold to the NP in January 1923.

670 may have ended up on the Cowlitz, Chehalis & Cascade in 1925, but Connelly's list indicates his uncertainty.

Class B-3 (Locobase 883)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004). A note on the diagram says:"Old W&C RR engines 4 and 5."

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class C-1 (Locobase 874)

From the The Tell Tale, August, 1950 (http://www.employees.org/~davison/nprha/niftyfiftytelltale.html) Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004). (the weights are higher than in the Tell Tale.)

NY Loco builder information from JF Webber's compilation as supplied by Allen Stanley in March 2004. This batch represented works #35-46 (February 1883). They were later renumbered 680-691.

R. V. Nixon talks about 684:

"The 684, [C]lass C-1, was built by the New York Locomotive Works and delivered to St. Paul the year the Northern Pacific was completed. It remained in main line passenger service for nearly 25 years and was then assigned to the Billings-Bridger passenger run. We who remember the bright red wheels, polished brass, clear-toned bell and peanut wagon whistle, can distinctly visualize the 684 starring in a Northern Pacific motion picture, along with the construction engine, Minnetonka."

Nixon adds that 684 was apparently to be dismantled in 1925, but instead was overhauled and sold to the Nez Perce & Idaho as their #4.

"For years," Nixon continued, "the 4 spot worked the 13 miles between Craigmont and Nez Perce, Idaho. Then the inevitable happened and she was laid aside in favor of more modern power. At the time of Nixon's account she seemed to be rusting away. "But even in her disgrace she's still a proud, high-stepping beauty," he said hopefully, "and waiting only for someone to come to her rescue."

Class C-10 (Locobase 873)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004). works numbers were 5714 in July 1881, 5902 in November 1881.

817 was sold in 1899, but 818 lasted on the road until December 1922.

Class C-12 (Locobase 859)

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

Manchester works #868-871.

Class C-14 (Locobase 860)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004). Works number was 5715.

Possibly the reason this was a single-engine class was the "Weston blr [boiler, Locobase believes]" mentioned in Connelly's notes.

Class C-19 (Locobase 880)

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

NY Loco builder information from JF Webber's compilation as supplied by Allen Stanley in March 2004. This quartet bore Rome works #249-252 (April 1887) and seem to have been the first engines delivered to the MU. When the MU was taken over by the Northern Pacific, these engines were renumbered 675-678.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class C-2 - 1883 (Locobase 10801)

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

Class C-2 / C-11 (Locobase 876)

Roster information from the Northern Pacific Railway Historical Society website page http://www.nprr.org/Lists/Class%20List/DispForm.aspx?ID=21&Source=http%3A%2F%2Fwww%2Enprr%2Eorg%2FLists%2FClass%2520List%2FAllItems%2Easpx (7 Feb 2004).

Works numbers were

1879

April 4584, 4589, 4590, 4593; July 4726, 4732; September 4776, 4778

1880

1881

February 5522, 5524; June 5673-5674; July 5714-5715; August 5794; October 5842

5846-5849, 5851, 5880, 5883

January 5997, 5999; March 6113, 6115, 6118; April 6125, 6149-6150, 6161-6162; July 6279-6281; December 6523-6525

Class C-2 / C-4 (Locobase 871)

Data confirmed by locomotive diagrams from 1900 hosted on http://www.nprr.org/Steam%20Diagrams/Forms/AllItems.aspx (7 Feb 2004). These are described as "Lignite Burners" on Larry Schrenk's all-time Northern Pacific list originally found on http://museumoftherockies.org/photoarc/nixon/nixon-loco/schrenk.html . Works numbers were 5997, 5999.

At a later date, the Northern Pacific grouped several classes of light Eight-wheelers under the common class ID of C-2. A few were re-classified still later, presumably to take account of the differences in capability represented by smaller or larger boilers. This pair may have had the smallest boilers of the class because the tube count is certainly the lowest.

Class C-20 (Locobase 881)

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

JF Webber's list of Dickson locomotives (conveyed to Locobase by Allen Stanley in March 2004) gives the works numbers as 605-610 (September-Ocotober 1897).

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class C-21 (Locobase 885)

Data from http://www.nprr.org/Steam%20Diagrams/Forms/DispForm.aspx?ID=18&Source=http%3A%2F%2Fnprha3%2Estsbeta%2Eiponet%2Enet%2FSteam%2520Diagrams%2FForms%2FSelected%2Easpx%3FView%3D%7B32C6F164%2DBD66%2D44D5%2DA8C7%2DDC3E454BA2D7%7D%26FilterName%3DID%26

NY Loco builder information from JF Webber's compilation as supplied by Allen Stanley in March 2004. This trio were works #350-352 (April 1888). When the St P & D was absorbed by the Northern Pacific, the latter railroad at first renumbered them in the 1000s, but later grouped them with the other 17"-cylinder 4-4-0s in the 600s.

Class C-22 (Locobase 877)

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

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 #1104-1107 in March 1886, 1194-1204 in March 1887.

The St Paul & Duluth appeared as a result of the reorganization of the Lake Superior and Mississippi in 1870. It was known throughout its history, both before and after the Northern Pacific's purchase in 1900, as the Skally Line.

Class C-23 (Locobase 870)

Of the six originally delivered, two were scrapped in the 1890s. (A short time to be in service -- were they victims of accidents or was the design flawed somehow?)

Class C-24 (Locobase 869)

Data from 1944 Northern Pacific Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection.

Class C-25 (Locobase 867)

Baldwin works numbers were 1723, 1732 in June 1868 and 1920-1921 in July 1869.

The first two entered service on the LS & M with names: William L Banning and William R Marshall.

Class C-27 (Locobase 864)

Data from 1944 Northern Pacific Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 2121 and 2124.

The LS & M collapsed in the Panic of 1873 and reorganized itself as the Saint Paul & Duluth in 1877. These two locomotives kept their numbers until the Saint Paul & Duluth was taken over by the NP. See Locobase 863 for the slightly more powerful pair that came to the LS & M shortly after these arrived.

Class C-28 (Locobase 865)

Data from 1944 Northern Pacific Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers were 2811, 2814, and 2821-2822.

These were produced at the same time as the Northern Pacific's A-1 class (Locobase 9298), but had slightly smaller boilers and slightly larger grates. When the LS & M failed to absorb the heavy shock of the 1873 Panic, it was sold to the St Paul & Duluth in 1877.

Only the 101 and 104 were taken into the Northern Pacific in 1901 as 1138-1139.

Class C-29 (Locobase 866)

Data from 1944 Northern Pacific Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection. Works numbers 3397 (September 1873), 3469 (October 1873), 3550 & 3553 (March 1874), 3593-3594, 3596-3597 (May 1874).

It wasn't very long after these locomotives were delivered to the LS & M when that railroad was thrown into financial convulsions by the Panic of 1873 and forced to reorganize. By 1877, the octet was relettered for the Saint Paul & Duluth, but retained its original road numbers. Later, the St P & D renumbered the class 28-34, having sold 112 to the W & SW.

In 1901, the Northern Pacific renumbered 5 of the class 1140-1144.

The 105, Connelly simply records, was "gone" (possibly as result of a wreck). 34 was sold to Standard Construction.

Class C-3 (Locobase 875)

Data from NP 1 - 1929 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. Class quantity supplied by the NPRHS's website http://research.nprha.org/Lists/Class%20List/DispForm.aspx?ID=13&Source=http%3A%2F%2Fresearch%2Enprha%2Eorg%2FLists%2FClass%2520List%2FAllItems%2Easpx, accessed 3 February 2007. Works numbers were 6535, 6548-6549 in December 1882;

6563, 6565, 6571-6572 in January 1883; 6600, 6610 in February; 6636, 6646, 6650-6651, 6676-6677 in March; 6704, 6707-6708, 6724, 6726, 6729 in April; 6730, 6735, 6739, 6740-6741, 6743, 6769-6770, 6776-6777 in May; 6787, 6790-6791 in June , 6905 in August; 6913, 6920, 6942, 6948, 6967-6968 in September; and 6955-6956, 6972 in October.

The Puget Sound & South Shore Railroad locomotive produced in March 1890 was delivered to the Northern Pacific instead as their 740.

Most of the class operated on the Northern Pacific until they were scrapped after 20-30 years worth of service, but several were sold:

NP numbers Railroad or Company Year New number(s)

706 H T McLeary Lumber 191101

722 Louisville & Nashville 190511 51

Appalachicola Northern 1929 101 (2nd)

727 Louisville & Nashville 190511 57

730 Appalachicola Northern 1913 101 (1st)

732 Chehalis & Cowlitz 191305 1

(later Cowlitz, Chehalis & Cascade)

735 North Yakima & Valley 191004 2

(later returned, then sold to Inland Empire Paper 192301

736 Minnesota & International 190605 20

738 Appalachicola Northern 190512 102

739 Spokane & Inland Empire 190604 4

(later Spokane, Portland & Seattle 56)

740 North Yakima & Valley 191010 3

(later returned and scrapped)

Class C-30 (Locobase 882)

Data from 1944 Northern Pacific Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection.

Rhode Island delivered these four locomotives in drips and drabs, producing a pair -- works #1779-1780 -- in 1887, then 1820 and 1937 in 1888.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class C-31 (Locobase 886)

Data from 1944 Northern Pacific Locomotive Diagrams book supplied in May 2005 by Allen Stanley from his extensive collection.

These were slightly bigger locomotives than the 1-4 delivered in 1887-1888 (Locobase 882), but had fire tubes that measured a foot shorter. They were produced as a pair by Rhode Island and were that company's work #2085-2086.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class C-32 (Locobase 861)

Data from a 1944 Northern Pacific Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection. Works number was 4925.

Baldwin delivered this engine in January 1880. It was sold to the Bellingham Bay & Southeastern in 1892 as their road number 1. The BB & SE discarded the locomotive in April 1904.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class C-33 (Locobase 862)

Data from a 1944 Northern Pacific Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

Surprisingly low-drivered Eight-wheeler.

The railroad was built as the Vancouver, Klickitat and Yakima, but the effort broke the company and it was reorganized as the PV & Y in 1898. In 1903, the NP took over the PV & Y.

NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.

Class C-5 (Locobase 872)

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

NY Loco builder information from JF Webber's compilation as supplied by Allen Stanley in March 2004. This quintet had works #6-10 (July 1882). They were later renumbered 743-747 and three (744-746) went on to the Louisville & Nashville as that railroad's 52, 58, and 53, respectively.

Class C-6 (Locobase 8144)

Data confirmed by NP Misc Steam Locomotive Diagrams supplied by Allen Stanley in May 2005 from his extensive collection. The Northern Pacific Railway Historical Society's comprehensive website has a complete listing of classes and engine numbers. http://research.nprha.org/Lists/Class%20List/DispForm.aspx?ID=16&Source=http%3A%2F%2Fresearch%2Enprha%2Eorg%2FLists%2FClass%2520List%2FAllItems%2Easpx, accessed 3 February 2007, shows that this class total 56 locomotives and came from Portland.

The diagram shows "New Portland" as the builder, which presumably refers to the Portland Company of Portland, Maine. The 56 engines supplied to the NP -- works #463-518 -- represent a little less than 10% of all the locomotives (628) this company ever built. Portland also supplied 29 C-13 class 4-4-0 locomotives in 1881-1883 in a series of small batches, road numbers 172-183,189, 191, 194, and 203-222. later numbered 870-898. Little else seems to be known about this class.

Class C-7 (Locobase 884)

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

builder information from B Rumary compilation as supplied by Allen Stanley in March 2004. Works number was 862.
