Right now I have two of the passenger cars ("First Class") and two of the open "frieght" cars ("Second Class") that go with Chloe. Hopefully if I oil the wheels and don't have much of a grade it will be OK.
That's the exact same load of cars that I'm pulling with my Chloe and it pulls it fine with the weights on the pilot. I do have figures and metal wheels installed in all the cars. I've been operating my Chloe with that set up for about five years now and I'm still on the original motor.
I don't know if it makes a difference quality-wise, but Chloe was made in Germany, not China like the latest products from LGB. All of my LGB products were made in Germany.
The quality of all of my LGB products is second to none in my opinion. I cannot vouch for what others have said about their experiences but all I know is that 100% all of my LGB products work flawlessly. I've had some of them since 1987 too.
