Part 1:    • Double the Power  Modifying the LEGO...  

Welcome back to Danjo Trains!
Finally, we have the long awaited Orient Express part 2: electric boogaloo.

In this video, I present the complete design of the motorized Orient Express that utilizes TWO large motors and a differential gear. I also briefly cover Pybricks, as well as showcase the train going around my layout. Free instructions for this design are available on Rebrickable (see link below).

Enjoy the show!
