The profile of this freight Ten-wheeler class shows a slender boiler with no significant taper at the crown of the firebox. Indeed, the firebox is quite shallow and rides above the very small drivers. The class had a short wheelbases as well as being quite low-slung. See Locobase 7196 for the 57" driver variant.
As noted in Locobase 7194, this design had a very low profile with a shallow firebox riding above the driving axles. In two instance, the railroad increased the driver diameter and the 52-B was the result.
The one difference between this quintet and the D-17/53-B is driver diameter; see Locobase 7194.
Possibly the larger diameter of this set of 5 D-17s (see the 57" version in Locobase 7193) was to enable the locomotives to handle mixed-traffic trains more readily.
After the 25-engine class shown in Locobase 7203, Baldwin added 4 more with slightly larger cylinders and a 2"-longer wheelbase. Adhesion weight also grew by 2 1/2" tons as the driver diameter increased by 4".
The Rock Island built two more to this design, but with smaller grates; See Locobase 7201.
Yet a third set of Ten-wheelers (the others being shown in Locobase 7193-7194) for which the only difference is driver diameter. In this particular case, the result is a pure drag-freight engine.
Most noticeable about these Brooks engines was the large firebox heating surface area for a narrow firebox. They had arched cab windows. 1101 ran on 69" drivers, which reduced calculated tractive effort to 18,680 lb.
Baldwin delivered the first of these Ten-wheelers in 1891. Compared to many other Ten-wheelers of the time, the profile showed a fuller boiler supplying larger cylinders. Placing the firebox over the rear two driving axles rather than between them allowed a shortening of the driving wheelbase.
Along with the 4 D-18-25-B locomotives Baldwin delivered to the railroad in 1892, it supplied a 5th that had a longer piston stroke and lower boiler pressure. If this was for comparison, the railroad apparently wasn't convinced and this remained a single-engine class.
When the Rock Island built two of its own Ten-wheelers using the boiler and grate dimensions of the earlier Baldwin engine (Locobase 7200), it shortened the piston stroke and raised the boiler pressure.
These followed by four years another set of Brooks Ten-wheelers. Differences lay in the increased boiler pressure, a slightly larger grate, and taller drivers.
Baldwin continued producing its run of Ten-wheelers for the B CR & N with this set of smaller freight locomotives. The cylinder volume stayed the same as the earlier (Locobase 7202) D-18s but the layout was more compact
Using the same design as its passenger pair of 1897 (Locobase 7201), the Rock Island ran off a dozen mixed-traffic locomotives. The combination of smaller drivers and longer piston stroke raised the tractive effort.
A true express passenger engine with a big boiler, tall drivers, and 11" piston valves for steam admission. This was a one-off simple-expansion variant of the Baldwin compounds produced in the same year; see Locobase 7208.
In same year as the mixed-traffic engines came these freight locomotives. As the end of the century loomed, cylinder volume, boiler capacity both began to burgeon. Grate area followed but the great jump was still to come.
Brooks delivered over 120 Ten-wheelers of the same design to the Rock Island beginning in 1902. Sturdy Ten-wheelers for passenger service, these locomotives had a curiously outdated set of domes on the boiler. From the start, however, they used Walschaert radial valve gear outside that actuated 11"piston valves. Like the 68"-drivered 14-B (Locobase 7213) and 14-A (Locobase 7216), the 14-Cs had 22 sq ft of circulating tubes that supplemented the firebox heating surface
At the same time Brooks was supplying the 57" freight engines (Locobase 7212), it delivered these 5 mixed-traffic locomotives. Like the freighters, the 54-Bs had 10" piston valves actuated by outside Walschaerts gear and Belpaire fireboxes.
As Brooks was supplying over 120 Ten-wheelers including 15 for fast passenger service (Locobase 7211), it was also delivering this local passenger variant. Like the 14-C, the 14-Bs had 22 sq ft of circulating tubes that supplemented the firebox heating surface; they also had 11" piston valves.
At the turn into the 20th century, Brooks enlarged its Ten-wheeler designs for the Rock Island and delivered this quintet. The five had a larger, shallower grate within a Belapaire firebox and larger cylinders with a boiler that was not quite outsized. The radial valve gear operated 10" piston valves. The cab windows were oddly placed low in the cab wall and had a continuous arch over two panes. See Locobase 7209 for the mixed-traffic variant.

From the start, however, they used Walschaert radial valve gear outside that actuated 11"piston valves. Like the 68"-drivered 14-B (Locobase 7213), and the 73" 14-C, the 14-As had 22 sq ft of circulating tubes that supplemented the firebox heating surface.
1454 had a slight variation in its firebox layout in which 27 sq ft of circulating flues combined with 183.1 sq ft of firebox heating surface to produce 220.1 sq ft of direct heating surface.
As Baldwin was delivering compounds, it was also supplying a couple of simple-expansion variants. These two were driver-sized for mixed-traffic service.
Locobase enters this one Ten-wheeler because of its small size and early entry. He knows nothing about the original railroad nor about the engine's subsequent career. He observes, however, that for the locomotive to appear in the 1904 book is testament enough to a certain value.
Baldwin delivered a slew of Ten-wheelers in 1900, most to a Vauclain compound design. This set was the high-wheeler express passenger quartet. See Locobase 7207 for the simple-expansion variant,
The Baldwin express passenger compounds were joined by these 15 mixed-traffic brothers. If the experience of other US railroads is a guide, these were quickly reconfigured as simple-expansion engines.
This class is essentially identical to the T-31s of the 1550 class (Locobase 5361), except for their builder and a slightly lower number of boiler tubes.
Data also from RI to 1951 Combined Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.
Some of the class were later fitted with superheaters, Walschaert gear, and 12" piston valves. At that point, the tube-flue count came to 181 2" tubes and 27 5 1/2" flues. Road numbers of these superheated engines included 1557, 1560, 1565-66, 1569, 1574, 1581, 1586-87.
