Model Railroading > BNSF heritage Trinity hoppers

I have been collecting the HO heritage Trinity covered hoppers from BNSF by Athearn and wonder if I missed the boat somewhere along the way.  I have NP, C&S, ATSF, Frisco, GN, FW&D, and BN, but no CB&Q and SP&S.  Have these two been released already so I have to find them on Ebay or elsewhere?  I can't think of any other roadnames than these, or have I forgotten one? 

The Athearn SP&S and CB&Q heritage covered hoppers were just released last month - Athearn 89613 and 89611.  The prototype of the SP&S car is a Trinity 5161cf car.  However the prototype of the CB&Q car, like a few of the other BNSF heritage cars already done by Athearn, is not a Trinity car.   

The prototype BNSF Trinity 5161cf covered hopper numbers only go up to 483999 (BNSF 471500-483999 are Trinity 5161cf) and the car numbers 484000 and up are Gunderson 5188cf cars (like the models done by ScaleTrains).

Some of the heritage car fleet are built by Gunderson. ScaleTrains offers those roadnames.
