[RFI] Damned Amtrak

[dalej]

You might consider a Timewave ANC-4 noise canx device.  I have one here.  It phase cancels the noise before getting into your receiver.  You would need an external noise antenna close as you can get it to the source of the noise.  Then keep in mind, it only will cancel out one noise.  If the noise is changing, re adjustment will be needed.  It sounds like you've got a bad case.  

Good luck
