The Department of Transportation may purchase active or inactive railroad lines, corridors, rights-of-way, locomotives, rolling stock, and other rail property, both real and personal, by installment contracts which create in the property purchased a security interest to secure payment of the purchase money. No deficiency judgment may be rendered against the Department of Transportation in any action for breach of a contractual obligation authorized by this section, and the taxing power of the State is not and may not be pledged directly or indirectly to secure any money due the seller.
