Tàu hỏa Duplo động cơ đôi mạnh mẽ

I am not done tweaking this design but I figured I should share it in the current form so that I can get some feedback.

After building some custom train track parts and finding that the standard Duplo trains have difficulty with long slopes and are just underpowered in general, I decided to find a design online.  I tried a few things I found on Thingiverse but they weren't very good and they genralyl lacked a flat build plate for the top of the train.  I felt that is really important so that you can do whatever they want with it.

I'm still very much experimenting with how to make the best wheel.  I've tried making TPU wheels, elastic bands over PLA wheels, and just straight up PLA wheels.  I'll include some wheels in the files but I might remove these and upload a more final version a later date.

What you need to build this:
