The 2D-P5 is an appropriate upgrade for the Lima/Model Power heavyweight coach (it being based on the PRR P70). The same goes for the NJ International brass R50b.
In N scale, American Limited used to make "some assembly required" 2D-P5 kits (not sure if they still do). More recently, BLI released 2D-P5 trucks for use on their P70 coach models -
