Finally, in September 1920, she began work as draftsman in the engineering department for the Baltimore and Ohio (B & O) Railroad.
 
In November of 1921, Olive was designated as the engineer of service. This was mainly due to an effort to keep the support of female passengers as cars and intercity buses became more common. Her responsibility was to improve passenger service on the B & O.
