Helm worked diligently to convince residents along the line's main route of the economic benefits it would bring. He persuaded many of them to help clear and grade land for the line and accept company stock as payment, and succeeded in selling stock subscriptions to people in the same area. Rising labor costs and troubles transporting materials raised expenses far above the projected budget, and at one point Helm personally redeemed $20,000 ($ as of ) of the company's bonds. Meanwhile, some observers accused Helm of mismanaging the company. The company's fortunes improved in 1857 when the city of Louisville provided $300,000 ($ as of ) in financial aid and the line was completed on October 18, 1859. Due to Helm's influence, the railroad's charter required all trains traveling through Elizabethtown to stop there.
