2 to keep CSX trains running at a very demanding operating capacity在句中什么成分

Accomplishing their mission requires a staff of dedicated professionals who can ensure availability of the locomotives, cars, track, and maintenance parts needed to keep CSX trains running at a very demanding operating capacity.

不确定,有没有ensure.......to do, 动词不定式做状语;to keep CSX trains running at a very demanding operating capacity在句中什么成分?

ensure的宾语是availability,与to keep ... 无关。

看看这么分析,能否帮助你理解这个句子的语法结构: 

who 主语

can ensure 谓语

availability 宾语[that is] needed to keep ... 过去分词短语做宾语的后置定语,不定式在过去分词短语中做状语
