45 U.S. Code § 823 - Administration of direct loans and loan guarantees
The Secretary shall prescribe the form and contents required of applications for assistance under section 822 of this title, to enable the Secretary to determine the eligibility of the applicant’s proposal, and shall establish terms and conditions for direct loans and loan guarantees made under that section.
All guarantees entered into by the Secretary under section 822 of this title shall constitute general obligations of the United States of America backed by the full faith and credit of the United States of America.
The holder of a loan guarantee made under section 822 of this title may assign the loan guarantee in whole or in part, subject to such requirements as the Secretary may prescribe.
The Secretary shall assure compliance, by an applicant, any other party to the loan, and any railroad or railroad partner for whose benefit assistance is intended, with the provisions of this subchapter, regulations issued hereunder, and the terms and conditions of the direct loan or loan guarantee, including through regular periodic inspections.
For purposes of claims by any party other than the Secretary, a loan guarantee or loan guarantee commitment shall be conclusive evidence that the underlying obligation is in compliance with the provisions of this subchapter, and that such obligation has been approved and is legal as to principal, interest, and other terms. Such a guarantee or commitment shall be valid and incontestable in the hands of a holder thereof, including the original lender or any other holder, as of the date when the Secretary granted the application therefor, except as to fraud or material misrepresentation by such holder.
If the Secretary makes payment to a holder, or a holder’s agent, under subsection (g) of this section in connection with a loan guarantee made under section 822 of this title, the Secretary shall be subrogated to all of the rights of the holder with respect to the obligor under the loan.
The Secretary may complete, recondition, reconstruct, renovate, repair, maintain, operate, charter, rent, sell, or otherwise dispose of any property or other interests obtained pursuant to this section. The Secretary shall not be subject to any Federal or State regulatory requirements when carrying out this paragraph.
The Attorney General shall commence a civil action in an appropriate Federal court to enjoin any activity which the Secretary finds is in violation of this subchapter, regulations issued hereunder, or any conditions which were duly agreed to, and to secure any other appropriate relief.
No attachment or execution may be issued against the Secretary, or any property in the control of the Secretary, prior to the entry of final judgment to such effect in any State, Federal, or other court.
The Secretary may charge and collect from each applicant a reasonable charge for the cost of evaluating the application, including appraisal of the value of the equipment or facilities for which the direct loan or loan guarantee is sought, and for making necessary determinations and findings. Such charge shall not aggregate more than one-half of 1 percent of the principal amount of the obligation. Amounts collected under this subsection shall be credited directly to the Safety and Operations account of the Federal Railroad Administration, and shall remain available until expended to pay for the evaluation costs described in this subsection.
Except as provided in this subchapter, the Secretary may not assess any fees, including user fees, or charges in connection with a direct loan or loan guarantee provided under section 822 of this title.
 So in original. There are two subsections designated (b).
