Bob Brook's Northern Pacific Z6. This was a static "photo op" because the locomotive could not negotiate most curves on the layout.
From Appalachian & Ohio 1.0
Michael - Bob Brooks tells me it is a Sunset NP Z6 (2 rail scale.)
Neat model trail.
Is BoB Brooks NorthernPacific Z1 an MTH model? What features does have if its not running on Proto Sond 2.0?
