I think the easiest solution would be tie all infrastructure funds railroads receive with the delays Amtrak incurred on their tracks due to freight trains. Do it to many times and you lose out all funding for the rest of the year.

Trying to block Amtrak from services should automatically incur a funding pause for those tracks.

The railroad lobbyists aren't who Congress would be afraid of if they passed such a law, it's the industries that make use of the freight rail system that would have Congress running for the hills. The US has an extraordinarily robust and high-capacity freight rail system. Anything that interferes is going to get extreme blowback from those who depend on it. Amtrak's very existence could be in danger if they started causing freight users logistics problems.
