Re: Chama Steam engine placement

Greg:
The rules were changed over the years as the bridges aged and the B&B department evaluated them. I have two photos of the San Juan doubleheading across both Lobato and Cascade in the late 40s with a 470 and a 480. Guess the 470 was light enough that the rule did not apply, or they simply ignored the rule that day.
The D&RGW had similar rules for the Almont and East River bridges on the Crested Butte branch, but a D&RGW engineer told me of crossing both bridges with two K37s and Rotary 00.
They tried that once in the Black Canon of the Gunnison and Rotary ON fell through the bridge.
