Narrative:

IFR departure via gjt localizer rv ffu slc. Center handoff 10. Just as we were switching to center, an small aircraft descended down over our nose while on practice approachs. We were both flying out on the localizer. Small aircraft descending at a speed slightly faster than we were climbing. No time was available for evasive action. The two aircraft on different gjt approach frequencys although no mention of the traffic was made to us.
