[quote]QUOTE: Originally posted by andrechapelon [quote]QUOTE: Originally posted by twhite Banger1: 32 cars and you had to do all THAT? Funny, my Rivarossi Allegheny will do that and more up my 2.4 WITHOUT traction tires, and my BLI AC-5 does that and more regularly, just out of the box. Maybe, like the UP prototype, the Lionel Challenger just isn't built for grades. You guys out there ever think about that? UP and their piddly little 1.5% over Sherman Hill? Maybe Athearn and Lionel are trying to tell you something--THE CHALLENGER IS NOT A HEAVY-DUTY FREIGHT DRAG ENGINE! At least not those little 97,000lb. TE UP jobs. You want pulling power? Get yourself an AC or a Yellowstone! [/quote] The UP Challengers were never designed to be drag engines, but a higher horsepower/speed replacement for the 4-12-2's. Both engines had essentially the same starting tractive effort, but the Challenger was good for roughly an additional 1000 HP. As for the Allegheny, it was also a high horsepower engine misused as a drag engine to haul coal and cost about 80% more than a Norfolk and Western A for a mere 1200 HP increment. The Y-6B. Now THAT was a drag engine. Andre [/quote] Well said, Andre. Like the Big Boy's, the Challengers were built to haul fast freight over steep grades, but not terribely steep.
