The electrified railway is a much better fit for this purpose as there are additional electrical connections between the rails but connecting additional grounding to those rails would cause issues with the electrical equipment and various sensors placed within the railway structure. When I did some tests once the DC (stray voltage) was ca. 20A and the voltage up to 50V.

Cool! 20A and 50V in combination? :-) Maybe you can modulate the 20A current. Just build a special class-A PA for VLF :-)
