In my review a couple weeks ago I expressed my desire to attempt a motorization of the latest (and best) Hogwarts Express, but shortly thereafter I began to lose faith that I'd find the time. Thankfully a very productive week left me with the better part of a day to work on this (and motivation to boot!).

In the video I discuss some of the viable options for attempting your own conversion, along with pros & cons, and I partly dissect my attempt to fully show off the arrangement of components & methods of connection. I believe my choice of M motor + PF 1.0 IR receiver in the locomotive & battery in the tender is one of the more difficult setups to pull off, but it allows remote speed control, provides good driving traction, and leaves the passenger car completely untouched for a fairly clean look in motion.
