Nashville, Chattanooga & St. Louis 2-8-0 "Consolidation" Type Locomotives

Class H-0-24 (Locobase 6868)

Data from NC&StL 9 - 1925 Locomotive Diagrams-CLR CHTS supplied in May 2005 by Allen Stanley from his extensive collection.

One-of-a-kind Consolidation from Baldwin with low drivers.

Class H-0-27 (Locobase 6870)

Data from NC&StL 9 - 1925 Locomotive Diagrams-CLR CHTS supplied in May 2005 by Allen Stanley from his extensive collection.

This Consolidation is virtually identical to the single engine of a year earlier. The principal difference is a slightly larger firebox and a boiler pressure setting that ups the tractive effort.

Class H-0-28 (Locobase 9843)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This single locomotive is described in the 1921 diagrams as a switcher. It had a narrow, but deep firebox.

Class H-0-28 (Locobase 6873)

Data from NC&StL 9 - 1925 Locomotive Diagrams-CLR CHTS supplied in May 2005 by Allen Stanley from his extensive collection.

Upright pair of Consolidations with relatively tall drivers and a small grate for the Dixie Line 2-8-0s.

Class H-1-12 (Locobase 6867)

Data from NC&StL 9 - 1925 Locomotive Diagrams-CLR CHTS supplied in May 2005 by Allen Stanley from his extensive collection.

Small Consolidations with very modest boiler proportions. All were sold or scrapped in 1915-1916

Class H-2-26 (Locobase 6869)

Data from NC&StL 9 - 1925 Locomotive Diagrams-CLR CHTS supplied in May 2005 by Allen Stanley from his extensive collection.

This quartet of Consolidations resembled the single locomotive shown in Locobase 6868, but with a big jump in heating surface and some expansion of grate area. The small tender suggests short-distance duty.

Class H-3-28 (Locobase 6871)

Data from NC&StL 9 - 1925 Locomotive Diagrams-CLR CHTS supplied in May 2005 by Allen Stanley from his extensive collection.

Locobase figures that repeating a 9-year-old design (the one described in Locobase 6870) to a virtual T must have been dictated by either a) axle-loading considerations, or b) the class shown as coming into service in 1906 was of an earlier vintage. The boiler was pressed a little harder, but otherwise there seem to be no significant innovations.

Class H-4-28 (Locobase 6872)

Data from NC&StL 9 - 1925 Locomotive Diagrams-CLR CHTS supplied in May 2005 by Allen Stanley from his extensive collection.

Upright pair of Consolidations with relatively tall drivers and a small grate for the Dixie Line 2-8-0s.

Class H-4-30 (Locobase 9841)

Data from NC&StL 2 - 1947 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This pair of Consolidations was originally delivered from Baldwin in 1902

Class H-4B-30 (Locobase 9844)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This pair of Consolidations was originally delivered from Baldwin in 1902

Class H4C-28 (Locobase 9842)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Class H5-29 (Locobase 8325)

Data from NC&StL 1 -1 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This looks like an enlargement of the Baldwin Consolidation that arrived on the N, C & St L two years earlier. Its firebox heating surface included 15 sq ft of arch tubes. Its appearance was marked by a small steam dome centered over the gap between the 2nd and 3rd driven axles and a capped stack.

The first of the class was retired in 1934, but several were superheated (Locobase 9845) and the last lasted until 1950.

Class H5C-31 superheated (Locobase 9845)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

When the H5 series was superheated, it received a relatively rare large-tube layout, Walschaert radial gear, and 13" piston valves.

Class H6A-36 (Locobase 9846)

Data from NC&StL 6 - 1951 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

When this class was delivered in 1902-1903, it was with saturated boilers. Some time later the N, C & St L superheated the class; see Locobase 8326.

Class H6A-39 - superheated (Locobase 8326)

Data from NC&StL 6 - 1951 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

When this class was delivered in 1902-1903, it was with saturated boilers. Some time later the N, C & St L superheated the class. The process involved the usual trade off between small tubes and larger flues. And the firebox heating surface now included 20 sq ft of arch tubese.

All of the class served at least 40 years each with the first being retired in 1946 and the last in 1952.

Class H7-36 (Locobase 9847)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Following right on the heels of the H6As (Locobase 8327), this class had the same power dimensions and grate, but substantially more heating surface.

See Locobase 8327 for the superheated update.

Class H7A-37 (Locobase 9848)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

For some reason, the second batch of H7s reverted to the smaller boiler originally produced for the H6s. All of the H7s were superheated to a common design; see Locobase 8327.

Class H7C-40 - superheated (Locobase 8327)

Data from NC&StL 6 - 1951 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

When the H7s (Locobase 9847-9848) were superheated, the modification involved the usual tradeoff of tubes and flues.

All of the class operated into the late 1940, with retirements beginning in 1948 and ending in 1952.

Class H8-40 (Locobase 9849)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

This class of relatively large, saturated-boiler Consolidations was supplied one at a time over 3 years. Baldwin works #23291 was produced in December 1903, 25772 came out in May 1905, and 3 more (29571, 29603, 29635) in November 1906.

At least some of these were superheated; see Locobase 9850.

Class H8C-40 (Locobase 9850)

Data from NC&StL 1 - 1921 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

When the 5-locomotive H8 class (Locobase 9849) was superheated, the weights stayed the same, but the boiler tubes and flues apparently shrank slightly. The firebox heating surface area increased thanks to the addition of 30 sq ft of arch tubes.

All remained in service until 1948-1950.

Class H9-46 (Locobase 8328)

Data from NC&StL 6 - 1951 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

These Consolidations were the most powerful 2-8-0s to operate on the N, C & St L, serving the road for more than 40 years. The firebox heating surface included 23.1 sq ft of arch tubes.
