Well Doug, a few facts you may not be aware of.
Over the last two and a half decades, in addition to the establishment of of the DCC standards, the NMRA has added standards for Proto scales and Fine scales in virtually all scales and gauges. And there have been minor adjustments to the original standards.
This includes trackwork, wheels, turnouts, everything. Turnout specs have been greatly expanded in to all of these areas.
The Data Sheets have been updated to include newer prototype information.
And the recently completed standards for LCC - layout command control.
So as technology and usage has advanced, the Standards and Recommended Practices have been reviewed, expanded, and adjusted as needed.
And in the last 20 years, all this data has moved from paper to electronic media - no small task in itself.
I do agree that the splintering of the hobby is partly the result of the passage of time. I have explained over and over, and only some people seem to understand its implications.
If we just start at 1900, in 1968 when I started in the hobby there were basically only seven decades of prototype history to choose from. Today there nearly 13. So even if the number of modelers has grown at the rate of the population increase since then, there are still less modelers “available” to model each decade.
And the available resources are equally diminished for each modeling era. This is a very real problem for today’s manufacturers. And it shows up very clearly if you model the transition era today.
The “wealth” of new high detailed RTR models does not come close to representing the transition era very well, let alone the 1900 thru 1940 era.
Fact is, with the possible exception of “famous steam”, most of the new high end RTR models are post 1980/90 or newer prototypes.
Personally, model trains has always had a historical component for me. In 1970 I was not interested in modeling 1970, and in in 2025 I’m not interested in modeling 2025.
If I were to choose an era other than my 1954 date, it would be sometime before the Great Depression, likely 1920.
20 years ago I was invited to work on the Data Sheet revisions because of my knowledge of Architecture and Civil Engineering. Unfortunately I did not have time back then.
Honestly your expectations of what would make the NMRA valuable to you seem unrealistic.
