Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899). See also PM 3 1929 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. Roster information developed by Art Million and Tom Dixon and presented on the Pere Marquette Historical Society website ([], accessed 1 March 2008). Works numbers were 3090-3094 in December 1898.
This is a hefty Mogul fitted with an Improved Belpaire boiler, firebox with 21 sq ft of arch pipes, and a tender of considerable capacity. Clearly, this engine wasn't meant to stay near the shops.
Within two years of this class's delivery, the Flint & Pere Marquette became the better-known Pere Marquette. At that time, the class was renumbered 210-214 and in 1902 they were renumbered once again as 223-227. 226 was scrapped in December 1929, 224-5, and 227 were broken up in 1934 (March, February, and February, respectively) and 223 lasted until January 1937.

Works numbers were 3759-3762 in February 1901.
This was the first set of Moguls supplied to the PM after its formation in 1900. The class had Belpaire fireboxes and "improved" piston valves.
Two -- 215 and 218 -- were scrapped in 1930; the other two were retired and scrapped in 1934.

When the PM went back to Brooks for more Moguls, it bought a batch that were slightly larger overall, but particularly endowed with a larger bigger firebox. The direct heating surface was augmented by 15 sq ft represented in 2 arch tubes. These were later superheated; see Locobase 9265.

Roster information developed by Art Million and Tom Dixon and presented on the Pere Marquette Historical Society website ([], accessed 1 March 2008). The diagrams show that the class arrived in two batches: works #25514-25523 arrived in 1902, 27642-27645 in 1903.
Alco delivered fifteen of these powerful little Moguls in 1901 (Locobase 9273). The Pere Marquette's own shops made over the locomotives later on. They retained the big firebox with 15 sq ft of arch tubes, and added a relatively small amount of superheater area. Still, the class proved long-lived with the last one leaving service in 1944.

Works #1271-1272 (September 1887), 1463-1468 (November 1888), 1556-1560 (August 1889), and 1768-1769 (November 1890).
This F & PM class of Moguls represented a consistent purchase of motive power over a 3-year period. Their modest dimensions and power output suggest a similar level of traffic over a railway that spanned Michigan from the Lake Erie port of Monroe in the Southeast to Ludington on Lake Michigan in the Northwest and to Port Huron and Bay City in the state's "thumb". Later the F & PM extended south to Toledo, Ohio.

Cooke delivered these large, heavy Moguls (works #28583-28585) in 1903. They operated for three decades, were never superheated, and were retired in 1934.

These small Moguls entered service well before the PM rebuilt them in 1900. The basic dimensions were petite to begin with and about the only change seems to have been a new boiler of the same size as the old one. The overhaul yielded another quarter-century of service with the later of the two being scrapped in 1926.
