I have pieced together 10173 over the last year and now I'm looking to motorize the train. I've read all the threads here on Eurobricks about motorizing it, but most topics seem to be about converting it to PF. I am more inclined to go down the 9v route because it looks more straight forward with less required mods to make it work.
With that in mind, I have compiled a list of the required 9v parts. I was hoping somebody could check the list to make sure that I am not missing anything (see attached screenshot).
Thanks in advance.
