Did any trix 2-8-2s come with traction tires? I thought they never came with them. This thing is a very solid puller, its the heaviest RTR 2-8-2 on the market, since the entire thing is diecast (unlike BLI or Bachmann or Athearn Genesis), and unlike the MTH 2-8-2 which is also diecast, this thing has additional weight inside the boiler, unlike MTH which has a smoke unit take up most of that internal space. I cannot give you an exact number on how much it can pull since my freight cars are likely weighted differently than yours, but if you need a good puller, this definitely wont disappoint.
