Did D&RGW run Mail/Express Trains, specifically in the 1950s?

About the closest thing to an M&E on the Moffat line would be the Nampa Mail which was the final home of the PAs. Most of the pix I recall of it was Eng, bag/mail and coach. The Tennessee Pass line would have a few head end cars on the psgr trains but most of the transcon mail went UP. Of course an imaginative DRGW modeler could certainly conjur up a washout/derailment on UP and detour all the delay sensitive mail, where else, to the D&RGW

If so, did Alco PAs ever pull these trains (such as on he AT&SF)?

Thanks,
