I like that they continue to offer this as an entry level model. Sure, the shell is clunky, but it has been tidied up, which helps. Obviously the most important feature to Bachmann is the price tag, which remains inviting.
With the improved drive, it should provide good fodder for the 3D printers among us to address the shortcomings of the boiler shell.
I have an example of the earliest version with brass gears and a burned out motor. It was basically a ripoff of the Trix 060 drive, with the gears on the back of the drivers, only on the opposite side of the Trix design. It turned out I could replace the old open frame job with a motor from the new generation 2-8-0 with hardly any modification. It's a reasonably good runner now, having a hardwired 8x8 tender installed.
