Nice consist Ron,
I have ordered the Crescent RPO from Jeff at the Train Loft. I don't know if one was lettered for the Crescent or not . But it looks good and along with the Crescent Reefer will give me a 9 car consist (which with a Ps- 4-6-2 is about four or five cars too long for my little attic layout).
My Lionel set has a lighter colored center band than MTH as shown in the partial photo below on my old mountain cottage shelf operation. Actually the first two cars(Baggage) are old K Line units painted to match Lionel's consist including the gold stripe. K Line's cars have a slightly lower roof line. The ACE Hardware Store in Banner Elk scanned a Lionel car and sold me a pint of heavily thinned latex paint which I hand-sprayed on in many coats. However that is MTH 1396 (with correct green roof) towing the consist. All my early MTH power was converted to TMCC by T/A Studios.
