Haines' most notable achievement was the construction of Sanford-Tampa Line in 1883-1884. In 1883, Henry Plant acquired a charter from the state of Florida to connect
Sanford, Florida and
Tampa, Florida by railroad. However, because of political wrangling in the state, Plant's charter was only good for seven months, from June 1883 until the end of January 1884. In order to succeed with the Sanford-Tampa Charter, Plant had to lay over of new railroad through thick sub-tropical forests, wetlands, and swamps of central Florida before his charter expired. Plant called on Haines to oversee the entire operation in the field. Crews of blacksmiths and wheelwrights were at work 24 hours a day to stay on schedule. ==References==
