The train is supposed to arrive an hour ago, but it didn't.

When you use "is supposed to" the possibility still exists that it will happen. If the train was expected an hour ago, to say it's supposed to happen doesn't make sense. It WAS supposed to happend, but it did not.

I prefer "the train was supposed to arrive an hour ago." I don't see any difference in "The train was supposed to have arrived an hour ago."

I'm not sure I'm understanding the difference.

The original train schedule had the train arriving at 3. Then, there were delays and the train was supposed to arrive at 5. Now it's 6.

1 and 3 OK. 2 - doesn't sound right. is supposed to always implies now or in the future, so it can't be used with an ago phrase.

4 John was supposed to have come an hour ago. Also OK.

By the way, the paraphrases you're using indicate you haven't quite got the meaning. (I think.)

The idiom be supposed to often has a meaning similar to must or have to. There is no true "supposing" (assuming, guessing, estimating) going on here -- except in the sense that "It is supposed that" can mean "It goes without saying that", "It is a duty to ...".
