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" 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 of arch tubes in the heating surface. But Brooks would deliver larger ones in the same period; see Locobase 9262-9264.
Freight Ten-wheelers from New York (works #5075-5076) 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 D RG & W and the PM. The latter retired the duo relatively early in 1915.
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.
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.
Identical to the 2 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.
Later in 1903, the PM added to its new collection of Ten-wheelers with these passenger engines (works #29395-29400) that probably had a similar, if not identical, boiler to the TAs delivered earlier. Sometime later, superheaters added to the power implicit in the large firebox (which included 17 sq ft of arch tubes). Of all the PM's 4-6-0s, these lasted longest, some serving until 1935.
The works numbers -- 26865-26866 -- show these to have been 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 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 less than the TAs.
Even as the nascent PM was taking delivery of 14 small Ten-wheelers (Locobase 9261), it was also procuring 13 of the larger engines shown in this entry. Works numbers for these low-drivered versions (187-189 had 63" drivers as shown in the specs, 1901-191 had 61" drivers) ran 27179-27183, which put them between the two batches of Ts. They had relatively big fireboxes whose heating surface area included 17 sq ft of arch tubes.
The TAs shown in Locobase 9263 were of a more passenger-oriented nature.
