The Milwaukee Road's class EP-3 comprised ten electric locomotives built in 1919 by Baldwin and Westinghouse. They were nicknamed Quills because of their use of a quill drive. Although they were good haulers and well liked by engineers, poor design and constant mechanical problems plagued them for their entire lives and they were among the first of the Milwaukee Road's electric locomotives to be retired.
