Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 72, pp. 165+ and Vol 78, pp. 258+. Works numbers were 57979-57982 in September 1924 and 58951-58954 in January 1926.
Continuing to buy small wood-burning Ten-wheelers from Eddystone, the V a M increased the design's power by increasing boiler pressure. Their fireboxes were designed to burn either coal or wood.
A later roster renumbering assigned 81 to 88 to these locomotives.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 79, pp. 262+. Works numbers were 60593-60596 in August 1928.
Although duplicating the dimensions of the 1908 CVM Ten-wheelers shown in Locobase 13456, this wood-burning quartet was a little heavier, had a wheelbase that was 2" (51 mm) longer, and a slightly heavier tender that had a wooden canopy over the front end.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 66, pp. 286+.. (Thanks to Teemu Koivumaki's 21 November 2021 email noting the replacement of the 19; see below.) Works numbers were 52793-52794, 52813 in January 1920, 53632 in September.
This class updated the Ten-wheeler design described in Locobase 13456 by extending the boiler tubes 45" (1,143 mm) and allowing more weight on the drivers.
According to Baldwin's specs, the first three engines in the 17 October 1919 order from the CVM had no number. The second was numbered 19 and given the name shown in Locobase's data and the third bore number 20 and no name. Gene Connelly's Baldwin production list shows the numbering order as 20, 19, 21. The follow up order for a duplicate made on 2 April 1920 also appears in Connelly's list as 21.
Teemu Koivumaki found an explanation for the odd sequence of locomotives. He cites Reg Carter's statement that works 52794 was damaged in transit and was replaced by Baldwin's works 53632.
All of the engines were equipped to burn either coal or wood. When carrying wood, the tender's capacity was calculated at two cords.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 40, p. 133 and 44, p. 108. Works numbers were 32826-32827 in June 1908, 34467-34469 in April 1910, 36287-36289 in March 1911, 38404-38406 in September 1912, 60593-60596 in August 1928.
Paulo Frontin was the second locomotive in this order, which was followed by several more. These wood-burning Ten-wheelers set the pattern for more than twenty engines that varied in cylinder volume, boiler size, and driver diameters.
The class was renumbered in the following order (as the road numbers related to the works numbers): 22,21, 24-26, 23, 27-28, 29-31.
