See Locobase 13124 for a brief description of this northwest Pennsylvania common carrier.
The 1 was sold in 1897 to Norfolk, Virginia Beach & Southern as their #6. When the NVB&S was incorporated into the Norfolk & Southern in 1899, the 6 was renumbered 26 and placed in the N&S's class B-4. It remained on the N&S until its retirement in October 1925.
The 2 was sold to the Palmer Stave Company in New Hampshire. Its last known operator was the New Hampshire Stave & Heading Mill at least until 1923.
NB: Locobase 11579 describes an Atlantic & Danville trio of locomotives with identical firebox dimensions (69 7/16" long, 34 3/8" wide, 65 1/2" deep in front, 64 1/2" deep in back). Locobase bases his estimate of the P&CA pair's firebox heating surface area on the known quantity given in Locobase 11579.)
This little American is fondly remembered by those who rode the C&PA; see Locobase 13124 for a brief description of this northwest Pennsylvania common carrier.
The 6 served the line until 1946.
NB: The DeGolyer catalogue showed the specs as residing in Volume 46. It wasn't until Locobase thought of looking into volumes by date of order that I found their error.
