I now have mine..
Interesting way the battery-holder works.. - A standard 2x3 (6 total) 'AAA' battery-holder, with a little handle on the front. This is held in the loco with a clip, in order to apply pressure to the connecting springs on the circuit-board in the loco.
NOTE:
It would not be possible to fit 'AA' batteries, the loco / hood is just too small.
A second set of cleaning attachments. - These fit over the skates, so are only held to the track by the springs of the skates. Adding extra weight would NOT improve cleaning, only track-adhesion.
All four wheels have traction-tyres.
Forward-off-reverse switch is a centre-off slide-switch, and is nicely concealed, but easily operated.
There is a small bag of detail-parts (bell and horn) which also contains a pair of Kadee adaptors.
Handrails are nicely moulded plastic. All appear straight (not always true, on some models), quite fine. Only time will tell how robust these are?
The supplied paperwork is quite comprehensive enough to show how to get the loco apart, and diagrams are included for wiring and internal connectors. - Nice!


There is a moulded 'inner-roof' to the cab, and this is designed to house a speaker. - I think I can get an after-market sound-card in there.
With the wiring information, and not being afraid to attack the circuit-board, I think I can re-purpose the existing switch for charge-off-run, and find room for a charging socket.
Overall, I am pleasantly surprised by this model..
Moulding seems 'crisper' than an equivalent LGB model (more definition to angles, etc.) though whether this equates to it being more brittle will be found over time. 'Finer, and crisper' sums it up.
Not sure the lights are really in the right place? Also, there is some 'bleed' of light through the surrounding plastics. - Lights are where they are so LED's can mount on the internal roof circuit board, I reckon?
Speed it runs at is sensible, and due to the light pressure from the springs, it is not going to cause any real damage to track IMHO. - The instructions suggest 2 hours-plus run-time from a standard set of rechargeables, and needing to run it for (probably) an hour to clean your track.. They also suggest it is really better for cleaning a continuous run, rather than an end-to-end configuration.
