The [[United States Army Transportation Corps]] (USATC) '''S200 Class''' is a class of [[2-8-2]] [[steam locomotive]].  They were introduced in 1941 and [[lend-lease|lent-leased]] to the [[United Kingdom]] for use in the [[Middle East]] during [[World War II]].

==Service==
===Middle East===
At least 85 S200s operated in the Middle East, including [[Egypt]], [[Palestine Railways#World War II locomotives|Palestine and Lebanon]].{{sfn|Hughes|1981|pp=70, 133}} One was destroyed by fire at [[Arish|El Arish]] in Egypt in 1942.{{sfn|Cotterell|1984|p=133}} 29 of this batch was later supplied to [[Turkey]] where they became the TCDD 46201 Class. In 1946, another 24 were transferred to [[Turkish State Railways|TCDD]] which added them to the same number series 46201–46253. 51 S200s built in 1942 served on the [[Trans-Iranian Railway]], where they became Iranian class 42.{{sfn|Hughes|1981|p=125}}

===Europe===
After the [[Allied invasion of Italy]], 31 S200s were transferred and used there. 30 of these entered [[Ferrovie dello Stato|FS]] stock as [[FS Class 747]] Nos. 747.001–747.030; the other one caught fire and was destroyed.

===Asia===

Thirty were donated to [[China]] by the [[UNRRA]]. [[China Railway]] designated these as class ㄇㄎ10 (MK10) in 1951, then reclassifying them as class 解放10 (JF10, ''Jiefang'', "Liberation") and numbering them 3711−3740.{{Citation needed|date=October 2020}}
