I found that cleaning inside the bogie only lasts a couple of mths, so i added extra pickups to the wheels, this cures completely and locos run very smoothly, ive done 6 so far.
Many thanks, done as you described and a vast difference in running on both locos. The bogie housings were dripping with oil/melted grease. Both locos had not been lubricated since being taken out of boxes.
I totally agree with every word, having had one of these models in my hand and had a good look at it, for £140 what do some people want. This thread is a total waste of time.
