A large focus of Visclosky during his tenure was improving the South Shore Line rail service. Visclosky managed to help secure federal funding for a number of improvements to the South Shore Line throughout his tenure, including funding for new overpasses and bridges. In his last term as a congressman, two major projects Visclosky had long advocated for to improve the South Shore Line, double tracking on the existing main branch and the construction of the new West Lake Corridor, received federal funding.
