20 ILCS 2705/2705-425
No funds available for operating or capital assistance under Section 5 of the United States Department of Transportation Act for rail freight services in Illinois may be expended without specific appropriation of those funds. Reimbursements for those loans that financially responsible persons are required by agreement to repay shall be deposited in the State treasury as follows: (1) the State's share shall be deposited in the fund from which the original expenditure was made, and (2) the federal share shall be deposited in the Rail Freight Loan Repayment Fund. In the case of repaid funds deposited in the Rail Freight Loan Repayment Fund, the Department shall have the reuse of those funds and the interest accrued thereon, which shall also be deposited by the State Treasurer in that Fund, as the federal share in other eligible projects. However, no expenditures from the Rail Freight Loan Repayment Fund for those projects shall at any time exceed the total sum of funds repaid and deposited in the Rail Freight Loan Repayment Fund and interest earned by investment by the State Treasurer that the State Treasurer shall have deposited in that fund.
