Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 26, p 287; Volume 27, pp. 116, 163; and Volume 28, p. 182 . Works numbers 23968 in March 1904, 24696 in September, 24847 in December, 25043 in January 1905, and 27225 in January 1906.
This quintet of Consolidations served the PCR for 30 years before the last three were retired in 1935. 109 was sold for scrap; 107-108 were retained for parts before being scrapped in 1940 (108) and 1948 (107). 106 crashed into a gasoline truck in August 1938 and was scrapped in October. 105 was scrapped in 1943.
