I saw the davenport at a hobby shop in Flint MI 2 weeks ago. Much heavier than expected. Regarding the two comment that simple articulated locos had two stacks is not true. The UP challengers and big boys had twin stacks, as did the later northerns including the 844. The UP designed draft arraingement in the smoke box gave the engines a larger volume of draft so they could burn more fuel to sustain the steam pressure at the speeds they ran. The most of the simple articulated locos had a single stack including the Unitah engines wich were simple. We now return you to your regularly sheduled argument... |
