Louisville & Nashville / Louisville & Nashville(L & N / Louisville & Atlantic / Lexington & Eastern 2-6-0 "Mogul" Type Locomotives

Class F-0 (Locobase 9792)

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

Class F-1 (Locobase 9793)

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

Class F-1 (Locobase 9820)

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

The L & N diagrams show several variations of this basic design, some of which trailed slope-back tenders for switching duties. The specifications remained the same throughout and the only difference on the boiler was the siting of the bell between the two domes on a couple and ahead of both domes on most of the rest.

Class F-3 (Locobase 9794)

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

Class F-3 - Belpaire (Locobase 9795)

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

This was an unusual locomotive for the L & N in sporting a Belpaire firebox.

Class F-6 (Locobase 9796)

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

Class F-6 (Locobase 9797)

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

Class F-7 (Locobase 9798)

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

Identical to L & N F-6 engines (Locobase 9797) except for drivers that were 3" taller.

Class F-8 (Locobase 8131)

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

As shown in the 1927 book, this class seems to have operated mostly as switchers. The low drivers gave them agood tractive effort for such small locomotives.

Class F-9 (Locobase 8132)

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

This small Kentucky railroad was absorbed by the Louisville & Nashville in 1909. The 7 engines were supplied over an 8-year period.
