Not that reconductoring should not be done, but it would be great to leave the existing lines in place and stringing a new set to allow for both AC and DC, which requires only 1 - 2 conductors per circuit. To do that would require a level of coordination and vested interest that likely only Tesla has atm. Berkshire is also a possibility (maybe after Buffett is gone and interest rates are lower) with the huge cash pile that would have made sense to at least pay for electrifying their rail lines given the cross interest with reducing (re)insurance claims.
