Following up to my own post, (that wiki continues as "early alpha"), two 
important tasks emerge:

1)  Denver RTD's University of Colorado A Line (train) needs nodes/ways added 
to OSM, tagged public_transport=platform to grow the route from 
public_transport:version=1 to v2.  Seeing this is a pretty heavily-travelled 
passenger=suburban route=train, this shouldn't be too difficult, and

2)  TIGER Review of existing mainline freight rail (primarily mainline BNSF 
routes Colorado Springs, Pikes Peak, Spanish Peaks and Walsenburg Subdivisions) 
will need some additional authoritative data sources (Colorado PUC?) to 
"untangle" them from UP lines:  they have blurred so much and are have gotten 
so confused that the original TIGER data are virtually incomprehensible as they 
exist in OSM at present.

Of course, keeping the wiki synced with the data in OSM is the whole point.  
Then we go beta and eventually Colorado/Railroads become "a pretty darn good 
set of statewide rail data, well-documented."  One state at a time, OSM rail 
data (from decade-old hoary TIGER data) do measurably and demonstrably improve.

Thanks, especially to Colorado OSMers/rail enthusiasts who have responded so 
far,
