Has the OMI NScale Brass Texas special train streamliner passenger car been released?

I have been running NScale OMI Brass EA7 (2000 2003) in the picture for the first time in a while.
I think I bought it about 20 years ago.
It's embarrassing, but I only own a locomotive, and I don't own a Streamliner passenger car.
At that time, did OMI also release NScale's Brass Texas Special streamliner passenger car?

 

These are not OMI and they are not brass, but they are N scale. Have you thought about the cars described in this thread?

Some are sold out and may not be available in Japan.

 

Mr. Windsor Spring, thank you very much for the wonderful information.
I learned about the manufacturer of the Rail Smith Model for the first time.
I think that the passenger car does not have to be Brass.
I also learned that the FRISCO MKT carriages were sold out quite a bit.
Thank you for letting me know that there are some things that are impossible to sell in Japan.
It's embarrassing, but NScale owns only two of these E7AAs.
I'm thinking of studying and looking into it.
