N MT SW1500 truck question

[u18b]

I have some questions about Micro-Trains SW1500 truck configurations.

Of course, when the SW1500 was first released (in NS), it had the old Life Like friction bearing AAR-A frames.

But have they already gone to the regular roller bearing AAR-A trucks in UP and BN locos?  It is hard to tell from low-rez photos.

I see that SP is the latest to be announced.  And it is exciting to see that MT will be doing the flexicoil trucks.

CSX cannot be too far behind!

My UP appeara to be AAR roller bearing but ill check it later after the kids are in bed.

The RB sideframe were released between NS and UP. Everything after NS had been equipped with RB. I also am looking forward to the flexcoil release.
