Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 52, p. 359. See also Mississippi Rails entry at [], last accessed 22 September 2011. Works number was 41353 in April 1914.
The DL&T owned timber stands in Louisiana and Texas and this logging Mikado worked in both states. The 200 first operated on the Neame, Carson & Southern (successor to the Missouri & Louisiana). It was later transferred to Texas, then sold to Kirby Lumber of Silsbee, Texas in 1925. That owner gave the engine road number 100. After another 3 decades, the 100 was scrapped in 1955.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 52, p. 361. See also Mississippi Rails entry at [], last accessed 22 September 2011. Works number was 41996 in June 1915.
The considerable growth in boiler size in the 201 suggests to Locobase that the logging Mikado delivered to the DL&T a year earlier was deemed too small for their needs. This The first example of this design was diverted to work on the Zwolle & Eastern; see Locobase 13187.
This one was ordered two months later specifically to fulfill the original 201 requirement. It was completed to the identical specification.
