Jones' adopted home of Elmira was a major stop for the
Underground Railroad. Most of the people who were escaping slavery that passed through came via
Harrisburg and Williamsport, continuing their route to Rochester or another "station." Elmira's participation in the Underground Railroad was significant due to its location between Philadelphia and
St. Catharines, Ontario; the final destination for many escaping slavery. At one point in July 1845, 17 people who were escaping slavery were in the Elmira area, hiding on farms and at other places. The completion of the
Northern Central Railway after 1850 further escalated Elmira's contribution to the Underground Railroad. The new railway allowed people who were escaping slavery to hide in baggage cars, making their journey quicker and easier. Jones became an active agent in the Underground Railroad in 1851. By 1860, Jones aided in the escape of 860 people who had been enslaved. He usually received the fugitives in parties of six to ten, but there were times he found shelter for up to 30 men, women, and children a night. It is believed Jones sheltered many in his own home behind First Baptist Church. Of those 860, none were captured or returned to the South. In 1854 the tracks from Williamsport to Elmira were completed. Jones made an arrangement with Northern Central employees and hid the fugitives in the 4 o'clock "Freedom Baggage Car," directly to
Niagara Falls via Watkins Glen and
Canandaigua. Most of Jones's "baggage" eventually landed in St. Catharine's. ==Employment==
