A few trains out of the cupboard today

It sounds really croaky. No smooth control of speed, it's either fast of slow with nothing in between.

A little video done on the Gopro this afternoon....

Only fast or slow on the problem loco would make me think drivetrain issue.... it's also been seen when one motor block is not working and the other is pushing the loco against a dead block. I think your NW2 should not have any traction tires.

And of course, my favourite type of G Scale locomotive, the F7s

And the biggest disappointment of the collection is this. Struggling to pull even one wagon. Wish it came with traction tires like its RC counterpart. Cant even buy the wheels as spares.

After my experience with my OcCre Street Car and short wheel base, are both axles driven, is there any axle compensation, and lastly is it heavy enough. My assumption is that the drive wheels slip when trying to pull more, and not that it is the motor not being "man" enough.
Is it track powered? My one of the same sans traction tyres pulls the house down. I took the weights out to fit battey power but then added roofing lead cut to shape between the wheels and the outside frames to compensate. Used small LGB screws to hold in place. Pretty well near the same weight as bought 1.31kg.

Its a piko, track powered and no tires. Useless, despite adding weights.

Interesting there is such a disparity in the experience.
So one thing often overlooked in the forever churning track vs battery power debate, is that battery powered people have no reason to "sand" or "polish" the rails, and they usually have brass track. The oxidized brass track had a lot MORE friction/traction as opposed to nice clean polished track.
Perhaps this is the difference between your two experiences. I've learned the hard way, try stainless steel drivers on slippery stainless steel track!
By the way, adding traction tires to that small track powered loco would severely impact it's power pickup, weight is all you can do. This is why some kind of suspension is really needed, if only on one axle. Look at an Aristocraft 2 axle motor block, one axle can conform to the rails, so with enough weight all 4 wheels have good contact.
No such suspension in your Piko mini loco.

Way to confustulate my eyeballs
Hm the disparity is so strange, just thinking out of a the box a little are both sets wheels getting movement under power. Sounds to me like only 1 axle is working suggesting gear issues on the other axle. As for the likelihood of dirt on the track contributing power for my one, sorry that is not the case as the traction on mine has always been the same and not that long ago I maintained track power in the shed thus the track was Squeeky clean in there. Haulage on clean track was no different.
