THE FOLLIES OF TRADEMARK YIELD MANAGEMENT. Triticale scoffs at attempts by prototype railroads to harvest rents from their heralds.

Altho, lucky for them, model railroaders are not political enough to rise up and organise a boycott, it is wondrously easy not to model the Union Pacific. Aside from the many competitors who see no need to resort to such measures, there is also a glorious tradition known as freelancing. One of the first truly great model railroads was the Gorre and Daphetid and I can expect as much acceptence and nearly as many contest points for models of Phoenix - Durango rolling stock as for those with known prototypes. There is also a trend toward starting over in a new scale and/or gauge; there may well be a disproportionate number of HO scale UP models cut up by people switching to On30.

The biggest reason that the Union Pacific is foolish for being so anal about trademark and IP is that altho their business is booming right now they are in competition with other railroads and with other forms of transportation. There are demographic reasons why antagonizing model railroaders and railfans is likely to be detrimental to the marketing of transportation service.

I think that last sentence means "traffic managers might have model trains, or kids who have model trains."
