Unable to rail minor axis allies

[AFV]

I noticed today that I was unable to rail Hungarian units thru a hex occupied by a Rumanian unit.
I get that they cannot *end* the turn in the same hex, but are they also not allowed to move thru it either, even by rail, or is this a bug? If this is intended, I guess I would have to ask, why? (I can understand normal movement thru a hex but not for it to include rail movement).

That's working as intended.

Cheers!

The 2 countries hated each other. Even the Germans kept them seperate on the battlefield so that they would not shoot at each other.
