Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 29, p. 162. See also George E Hoke, "The Railroads of the Compania Minera de Penoles", archived at [] . (Thanks to Greg Maxwell for his 27 August 2021 email noting the incorrect road number 14 for the E&P 8.) Works number was 28806 in August 1906.
The E&P was a small Nevada narrow-gauge shortline originally built to exploit the thick veins of silver and lead ore. It eventually included 90 miles (145 km) of main line and remained in operation from 1874 to 1910. The latter year saw several miles of track flooded by heavy spring runoff and rain and the company declared bankruptcy.
Although the line would reopen as the Eureka & Nevada and remain in operation until 1938, the 8 was sold off by the new owners to the Sumpter Valley of Bates, Ore. The SVRR renumbered it 14. It was retired in 1931.
