Both beauty and ugliness are in the eye of the beholder.
Thats right Mark, thats how I can think a late Cab-forward is the most gorgeous articulated ever, but someone else may think its a stupid lookin’ contraption.

Aggro,
You have something there! I’ve never been able to bring myself to buy a Rivarrossi Cab Forward, because it is flexible at the wrong end! While the cab end engine unit is rigid on the prototype, on the model it is articulated, so on model curves, the cab “throws over” , something that doesn’t happen to the real thing!
Does the BLI model have this problem, or does it need huge curves?
My vote would really have to go to the Rivarrossi/Mehano F-M C line cab unit, however. I bought a couple for about $5 (new) which is about what they are worth, because they are almost historic, one of the first mass production HO diesel units, dating from the mid 1950s.
(I’m not really down on Rivarrossi - I like a lot of their models!)

My BLI AC-5’s cab doesn’t overhang that much, even on 24" radius curves. Not far enough to wipe anything out.
LIghtbender: Thanks for the photo of your MDC Climax. How could anyone resist it? It’s like a cat-show, everyone’s there to show off all of their purebred Siamese, Abys or Maine Coons, but the cage that gets the most ‘oohs’ and ‘aahs’ is the one containing the battle-scarred Red Tabby alley cat with one ear. Like I said, so butt-ugly that it’s CUTE! And you’re right, a buddy of mine has one and it wobbles and whines through bad track like a champ.
