Via Rail points
 

Is it possible to transfer Amtrak points to Via Rail?
Or maybe some other reward program can transfer their points to Via Rail?
I couldn't find any yet.

I think the quick answer is no to both.

There is no earning, transfer or redemption options between Amtrak and Via. I am also not aware of any portal like Points.com for moving points between the two programs, even via am intermediary program. One would think that the two major North American intercity rail systems would have reciprocal program arrangements, but they do not.

I am a member of both Amtrak Guest Rewards and Via Preference. There is no way that I know of to transfer points between them.
