Please help identify 2 trains!

[momof4]

I have just received some of my father's trains. I have been doing interesting research on them and their are 2 that I cannot find anything about. One is a blue hopper that was in an Atlas box with a Rivarossi label. (See 1st 2 pictures).
The other is a Bachmann missile load (item no 5506)(see 3rd pic). I find PLENTY with a carrier that is either no name or an L&N. The one I have is an ATSF. Can you please tell me if either of these are rare or where I can find more information on them? Thanks so much in advance for any help.

I can't get any of the pictures to attach.

If you're wondering if they're valuable collector's items (or whatever), the answer is no. Both cars were introduced in the late 1960's and were produced in the thousands (tens of thousands?) over many decades. Worth a few dollars, but no more than that.
