It is quite 'basic'. - Well from a Garden-Railers' point of view.
The track has a 'rough' moulded top-edge to it, and the loco has 'traction tyres on all four wheels of the powered bogie.
The tipper is fixed-axle, as was stated the bogies stock has one axle per bogie.
fixed couplings on the tipper, the rest are on the bogie-frames, so will swivel.
It says' 'multiple layouts' for the track:
I get four; Circle, circle with straight in each quadrant, one-straight oval, two-straight oval..
Looks to be you have to press the light on the loco to make that work? - No batteries at the moment..
There is some minor cosmetic damage on my loco, but for £16.00, added to the fact I probably won't be able to live with the chrome anyway, I can't complain.
