MTH had a display at York many years back when they first released the model. They had the Big boy running on what looked like a ridiculously tight set of curves. I can only imagine it was to show that it could do it? I felt it made the engine look bad. The boiler overhang caught my girl’s eye and she said she liked how it looked. I used that comment to acquire my first Challenger! She stayed quite for years after.
I modified all my Challengers using Ray Manley’s pages and adding springs to make the front drivers pull harder. I didn’t know that MTH had modified their bigboy’s to include that. They also have steel frames and drivers to add to pulling power. I’m excited to get one to compare against the Challengers. The included DCC control will probably never be needed on my RR as I run full DCS. I do like the use of caps and the removal of any polarity issues with the new PS3 system. I have plenty of PS2 models that still work with the new PS3 thankfully.
I may sell off a Challenger down the road if she does her weight on my RR. I still can’t find out how much a MTH Triplex will pull. Seems that I snap or have couplers fail somehow, when I get past 100 cars.
