Class Details by Steve Llanso of Sweat House Media

Class 11-12 (Locobase 16068)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 13. p 219 and Volume 14, p. 169. Works numbers were 9597-9598 in November 1888 and 13096 in December 1892.

These were delivered to the M&NG, which converted to standard gauge at that time and established a through route from Atlanta to Knoxville. Locobase uses heating surface data from a set of Virginia & Midland engines (Locobase 11870) delivered in 1887 and fitted with exactly the same firebox dimensions as well as identical counts, diameters, and lengths of firetubes.

Alas, the M&NG entered receivership in 1891 and only re-emerged in 1896 as the Atlanta, Knoxville & Northern. In 1902, the Louisville & Nashville took over the AK & N and renumbered this trio 137-139.


Class 11/D-0 (Locobase 9767)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3034, 3036 in July 1882.

Prince's list had several class D-0 locomotives, but an evaluation of present and former road numbers using both Gene Connelly's roster and the Railroad & Locomotive History roster shows that at the very least, the data refer to the two locomotive works numbers shown above.

These engines were delivered to the P&A and turned over to the Louisville & Nashville in 1891 and renumbered. Renumbered again in 1897 as numbers 2 & 3, the pair was divided by a later variation in wheel diameter. 62" road #2 was classed D-0 and her stablemate was placed in class D-8 with 68" drivers.


Class 15/D-0 (Locobase 9773)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class 5/D-0 (Locobase 9771)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works number is uncertain.


Class 67/D-0, D-8 (Locobase 9778)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. DeGolyer, Volume 5, pp. 19 and 87. Baldwin works numbers were 2080, 2083-2084, 2086-2087, 2090 in February 1870; 2093, 2096-2097, 2101 in March; 2212, 2215-2218 in August.

When these engines were delivered, they had 160 fire tubes that measured 11 ft 8 in (3.56 m) long each.

One of this class was converted in 1875 to a Ten-wheeler that ran on 58" wheels and was driven by 18" x 24" cylinders. A few others were rebuilt, but most served the L & N in the 20th Century. The first retired in 1914, the last in 1933.


Class 76/D3 (Locobase 9677)

Data from Emory Edwards, Modern American Locomotive Engines, (Philadelphia: Henry Carey Baird & Co, 1883), pp. 120, 125. Works numbers were 2436 in April 1876, 2437 in August.

Shown in a table of drawings and data describing the locomotives shown at the Philadelphia Centennial Exhibition of 1876, this design featured the biggest, broadest stack. A wood-burning engine needed a lot of spark-arresting area to capture all the cinders and this engine's cabbage stack looked equal to the task.

When the M&M was taken over by the L&N, these engines were placed in class D3.


Class 9 (Locobase 12660)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 25, p. 225. Works number was 22183 in May 1903.

Obviously the L & NW was lightly built because this Eight-wheeler significantly underachieved compared to other 4-4-0s then in service on the US standard-gauge lines.

NB: Evaporative and direct heating surface areas are estimates based on locomotive supplied to the Charleston & West Virginia (Locobase 12255) whose tube count and length were identical and whose firebox dimensions varied by only 1/8" of an inch in grate length.


Class D-0 (Locobase 8133)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

Located in the coal fields of Kentucky, this little road was begun in 1916 to link Loyall, Ky with the L & N's main line at Corbin; the L & N acquired all of the C & M's capital stock and leased the road beginning 1 January 1927.

Locobase believes he has solved the mystery of the original owner of this 4-4-0 and the three described in Locobase 9777. The Louisville & Nashville bought 15 engines of identical size from Baldwin in 1871; these are shown in Locobase 9778. (Another possibility is that this was Midland Pennsylvania #1, which is credited with works number 43007 in March 1916. But Locobase has described another MP 4-4-0 of larger dimensions (14328) that seems a more likely stablemate than the dimensions shown here.)

The Eight-wheeler that eventually came into the Louisville & Nashville was quite small and light for 1916 and clearly intended for branch-line service. It seems certain that the L & N supplied the C & M locomotives.

And so the little 4-4-0 did serve until its retirement in 1947.


Class D-0 (Locobase 8142)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

According to a compilation of Pittsburgh locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, works numbers for 107 was 772 and it was delivered in February 1887.

When it was delivered, the 33 ranked in the top third in the size of boiler, but its relatively large firebox and grate areas exceeded an even higher percentage of Eight-wheelers put into service in the mid-1880s.


Class D-0 (Locobase 9768)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works number may have been 4402 and it may originally have been ordered by the Findlay, Ft Wayne & Western as their #3.


Class D-0 (Locobase 9769)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

This quintet was delivered to the L&N in 1870 (Locobase 9778) as part of a bigger order. Many were rebuilt by the railroad in last few years of the Century. Originally numbered 83-87 with works numbers 2212, 2216-2218, and 2215, the group was rebuilt to the dimensions shown above.


Class D-0 (Locobase 9770)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class D-0 (Locobase 9775)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class D-0 (Locobase 9776)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class D-0/D-12 (Locobase 9774)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class D-10/D-0 (Locobase 9780)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3607-3608 in January 1886, 3615-3616 in February, 3617-3618 in March.

These were delivered with 67" drivers, but by 1927, the engines had been fitted with 64" drivers.


Class D-11 (Locobase 9772)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The firebox heating surface includes 14 sq ft of arch tubes.


Class D-11 (Locobase 9781)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class D-13 (Locobase 9783)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The firebox heating surface includes 14 sq ft of arch tubes.


Class D-14 (Locobase 9784)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. See also DeGolyer, Volume 10, p. 207. Baldwin works numbers included 6152, 6158 in April 1882; 6378-6379 in September; and 6558, 6560 in January 1883.

The L&N's diagram suggests that this class was rebuilt with a stronger boiler. As laid out in the 1882 specifications, the engine was to put 46,000 lb (20,865 kg) on the drivers and 70,000 lb (31,752 kg) for the engine.

Kentucky Central was taken into the Louisville & Nashville by 1891, at which point this class was renumbered 433-438. Six years later the class was again renumbered 38-43. The class was scrapped over a 15-year period from 1916 to 1931.


Class D-15 (Locobase 9785)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

The L&N took over these three Eight-wheelers when they bought out the Atlanta, Knoxville & Northern. For the most part, the engines were unchanged from the time they were delivered in 1887 to the Marietta & North Georgia (Locobase 16068).

Years later, the class received new boilers and fireboxes that were substantially smaller than the original.. The firebox heating surface includes 14 sq ft of arch tubes. 137's driver diameter was now 63"; 138-139 rolled on 64" wheels. The latter two put 1,200 lb more weight on their 64" drivers, which contributed to a 1,600-lb increase in overall engine .

So renewed, all three locomotives rendered almost two decades more service before being scrapped in 1933.


Class D-16 (Locobase 9786)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.


Class D-20 (Locobase 9789)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

This Eight-wheeler was rebuilt by the L&N from one of two Rhode Island-built 4-6-0s delivered in 1891 to the Atlanta, Knoxville & Northern as their #29. (Originally numbered 23, this was works number 2359 and was delivered as one of a pair, the other being works number 2360 and road 24.)

When modified, the firebox heating surface included 11 sq ft of arch tubes. The 141 was scrapped in 1934.


Class D-20 (Locobase 9790)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

This Eight-wheeler was rebuilt by the L&N from a Rhode Island-built 4-6-0 built in 1891 for the Atlanta, Knoxville & Northern as their #30. When modified, the firebox heating surface included 11 sq ft of arch tubes. The 142 operated until 1937.


Class D-21 (Locobase 9791)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection.

When the L&N acquired these locomotives in 1891 with the Alabama Mineral Road, they were still the Ten-wheelers they'd been when Baldwin (as Burnham, Parry, Williams & Co) delivered to the Anniston & Cincinnati in 1889 (Locobase 11571).

In 1906, the two were converted to the 4-4-0 layout shown in this entry. The makeover involved installing a longer boiler with more tubes as well as a larger grate.

The 144 was scrapped in 1934, but the 143 served throughout World War II before its dismantling in 1946.


Class D5 (Locobase 9777)

Data from L&N 8 1927 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3015-3018 in June 1882.

The Cumberland & Manchester was built in Kentucky by local interests and reached from Barbourville 23 miles north to Manchester when it opened in 1917. It later became a branch of the Louisville & Nashville. Locobase believes that these locomotives were supplied at the startup by the L&N from the 15-locomotive class described in Locobase 9778.
