Just picked mine up yesterday from the local Train Shop and did not unbox it until today. Wow! Lionel has done an incredible job on this Locomotive.
I unwrapped it and set it on the track. Paint and graphics are flawless. I powered up my 15B transformer, listened to the Railsounds come to life and all the various lights turn on for the 1st time on my layout.
There are lights all over the place on this model.
Headlight(of course), numberboards, marker lamps, cab light, firebox ashpan, tender markers and back-up lite.
Tons of detail and the front smokebox is looks very accurate(unlike it's larger "O" cousin).
Lionel re-designed the tender, so the water cistern(sides) curve down properly to narrowed pedestal wheel base. This is one of the major distractions of the AF Bigboy, IMO.
Ok, so how does it run? Well, she started off well, running on my 40" diameter, folded dogbone loop. About the 2nd curve, she stalled. I thought it was binding in the mechanism, but I ran it in reverse and then forward again.
Same thing happened! I noticed this time that the rear engine was trying to move and the front engine was dead.
I decided to lubricate all the axles, valve gear including the tender wheels.
I tried again and she appears to be running great in conventional mode, with no problems now(Whew!). I think it might have been a momentary electrical contact issue to the motor of the front engine.
This has been the only "Glich" so far.
I am thinking a re-designed Big Boy by Lionel will be a good bet in the future. Al
