First, a tongue-in-cheek note to Mr. Dye:
This engineer suggests that the shipping or erection damage be included - to make it really authentic. It doesn't take an engineer to find the damage - just stare at it long enough. And I'm talking about several inches out of straight.
Wonder what the Osmose report of a few years ago had to say. A copy is in the FC&TSR Osuna Road library. Probably also in the Commission's office in Antonito.
Second: One of the Chama spans matches one of the Creede Branch spans - at least from my "examination" from Highway 149.
Did the CRM get the drawings for these bridges?
Probably not, if UP is still using one of them.
There is a high probability that these were originally designed and built for standard gauge railroads. The strength required to handle the impact loading from reciprocating drivers has given the Diesel powered railroads of today a free ride over bridges of long ago. Do any other spans of this design still exist in North America - for railroad or trail use? I'm not particular.
