I have the 5 postwar Lionel Lines 2500 aluminum streamliners (baggage, 2 pullman, vista dome, and observation) plus the modern era combine, diner, full vista and duplex roomette that I have added Lionel Lines plates to. All with silhouettes. Running a 6464 boxcar of a matching roadname with the ABA F3 engines and a milk car or horse car or merchandise car makes for one prototypicaly long train and a dream come true for this baby boomer. Plastic just doesn't do the same for me.
Well, unless it's the 2400 027 cars and the 2600 Madison cars.
Postwar rules!
