I received mine yesterday and was put to the test today. Excellent model, run in on the rollers and then load tested to 8 MK1's. It struggled a bit so I took 1 off and ran fine. I then added mt 5 GNR 4 wheelers to the back to add a teeny bit more weight though only minimal. Ran fine without any slip. BUT beware of the NEM pockets on the tender, make sure its fully pushed in. After a few laps of the layout, all of a sudden the loco broke free and before I could stop it, it ran into the back of the 4 wheelers, with the NEM still attached to the lead coach. Luckily there was no damage to loco or coach, but you have been warned. Or maybe i was just unlucky.
