"I must not have enough experience with model trains because I am having a hard time figuring out how to use this accessory. The only instructions that came in our box were how to install the batteries - which I could easily have done without - batteries are easy to install, using a new remote control is more difficult and could have used instructions. I have even looked here and throughout the Lego sites and no one explains what each of the controls... control.
I'm sure once I figure out how to use it, it will be great!"
