I know, there are a few parts still missing. :) The thing was that this locomotive is real scale dimensions, and my track has a much narrower radius than scale, so this locomotive has serious trouble in the turnouts. It handles curves quite well, but the turnouts is really tough with these big wheels. I've had on my to-do-list to try with smaller wheels, but I've devoted more time into developing other rolling stock that is more suited to the track, also because this locomotive is so big that you cannot have cars attached to it with my tight curve radius. With the Hectorrail 141 I departed from scale dimensions and made it significantly smaller while trying to maintain a scale look, and it works a lot better.
