Class T (Locobase 9261)

Data from 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). The diagrams show that the class arrived in two batches: Schenectady works numbers 25514-25523 in 1902, Brooks works numbers 27642-27645 in 1903.

Two years after the PM was formed out of several Michigan railroads, the new company purchase a relatively large number of these Ten-wheelers. Four of the 14 had 67" (1,702 mm) drivers, the other 10 turned the 63" wheels shown in the specifications. These were still pretty small 4-6-0s, particularly for the time and compact of wheelbase too, although their fireboxes were relatively large and included 14 sq ft (1.30 sq m) of arch tubes in the heating surface. But Brooks would deliver larger ones in the same period; see Locobase 9262-9264.

Class T1 (Locobase 9266)

Data from 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 5075-5076 in 1899.

Freight Ten-wheelers from New York that fell on the small side, but had relatively large fireboxes riding over the driving axles. They used saturated steam right up to retirement in 1928.

A pair of Ten-wheelers that came from New Hampshire (works #1015-1016) to offer mixed-traffice service to the DGR&w and the PM. The latter retired the duo relatively early in 1915.

Data from 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).

Ocean-state Ten-wheelers (works #2719-2724) that were small even for the early 1890s, but which rode lightly and served the C & WM and the PM until the late 1920s.

As with so many other locomotives of the period, these Dunkirk, NY engines somehow seem more modern than those of other builders of the time. They had big, relatively shallow fireboxes with plenty of direct heating surface.

Class T3 (Locobase 9272)

Compared to other Pere Marquette Ten-wheelers, this engine (works #1552) had a relatively short wheelbase devoted to adhesion or, looked at the other way, a long stride for its adhesion wheelbase. Otherwise, this was a typical freight 4-6-0 that served for about 30 years.

Class T4 (Locobase 9269)

Data from 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).

Identical to the two Ten-wheelers with 57" drivers (Locobase 9268), this third engine (works #4795) went into mixed-traffic service where its taller drivers would have allowed higher speeds but generated less tractive effort. Like many of the PM locomotives inherited from predecessor roads, 164 was retired in the late 1920s.

If you dig into this locomotive's past through Connelly's Baldwin records, you discover that it came to the F & PM with another engine in 1878 (works #4486-4487, engine numbers 45-46). It's hard to tell whether both were originally Moguls or one was a Mogul and the other was a Ten-wheeler. Locobase suspects the former was true, because when 46 was rebuilt in 1896, its firebox remained unchanged and had a very high ratio of total heating surface to grate area. This indicates installation of longer boiler tubes for more heating surface as well as the likely reason for its early scrapping in 1913.

Class TA (Locobase 9263)

Data from 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 Works numbers were 29395-29400 in October 1903.

Later in 1903, the PM added to its roster of Ten-wheelers with these passenger engines, which were delivered with 69"(1,753 mm) drivers.

Sometime later, superheaters added to the power implicit in the large firebox (which included 17 sq ft of arch tubes) and the class rolled on the 73" wheels shown in the specs. Of all the PM's 4-6-0s, these lasted longest, some serving until 1935.

Class TB (Locobase 9264)

Data from 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 26865-26866 in October 1902.

These Ten-wheelers were built between the two batches of small T-class engines (Locobase 9262). The pair were freight engines, but had bigger boilers and quite a sizable firebox that included 17 sq ft (1.58 sq m) of arch tubes. The PM later superheated this class to essentially the same design as the TAs (Locobase 9262), but somehow managed to trim the weight off to the point that these weighed 4 1/2 tons (2.8 metric tons) less than the TAs.

Class TC (Locobase 9262)

Data from 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 27179-27183 in July 1903.

Even as the nascent PM was taking delivery of 14 small Ten-wheelers (Locobase 9261), it was also procuring thirteen of the larger engines shown in this entry. Gene Connelly's Alco production list names the Santa Fe Central as the original buyer of this quintet, which had 50-54 as road numbers. The SFC possibly never took delivery of the set.)

So they wound up in Michigan. They had relatively big fireboxes whose heating surface area included 17 sq ft (1.58 sq m) of arch tubes.

The TAs shown in Locobase 9263 were of a more passenger-oriented nature.
