Now I have to admit, other then the power function trains we own I am not very familiar with using them.
Just to see how it worked I took off the handle that you manually turn, and put the motor on... If it had wings it would have flown!! Both horses flung off it... went that fast!
Now I had to work out how to use the gears... At first (what took about an hour) I had this 16 stud long line of gears to slow it down. but it was still too fast, until I pick this little piece up out of the tray...
It slowed it down to the perfect speed! What was a gear line of 16 studs long has now been reduced to 1 stud away from the hut all because of one piece.. Below is a quick video of it in action.
