Tex. Utilities Code § 186.055

If a railroad requires a utility, common carrier, cable operator, or energy transporter to obtain from the railroad a right to use a railroad right-of-way, the railroad shall produce, if requested in writing, the readily available documentation from the railroad's records indicating the extent of the railroad's right, title, or interest in the property sought to be used by the utility, common carrier, cable operator, or energy transporter. The utility, common carrier, cable operator, or energy transporter shall reimburse the railroad for the reasonable cost of producing the documentation as required by this section. The reimbursable cost, including internal costs, may not exceed $500, unless the parties agree otherwise. A railroad that produces documentation as provided by this section is not limited or prevented from asserting a right, title, or interest in real property based on documentation that has not been produced under this section.
