"If by "very positive" you mean "a can of worms", I agree.
The problem is reverse compatibility. The number of new trucks that come on the market every year is quite small, and if today manufacturers adopted a standard going forward, it would be decades before a majority of trucks on the market met the standard."
Larry makes a very good point...one that I allude to when I point out that I must and intend to continue to stay with the Code 110 wheel as defined in RP-25 because I have about 700 locomotive axles with Code 110 wheels on them...the majority on brass steam engines. As I've noted in the past, I'd be glad to promote...even insist that everyone on the STMFC use P87 wheels as soon as someone comes down and installs P87 wheels in all my engines and redoes all 55 of my turnouts during a weekend.
"Retooling existing trucks to meet this standard would be expensive and result in no measurable increase in sales."
Not gonna happen, of course. The only practical option is for new tooling to reflect newly developed dimensions for truck sideframes, etc so that modelers can have more accurate dimensions for such new cars.
"And if the standard matches manufacurer A's current practice, the rest of the manufacturers will have an unfair financial burden placed on them. Retooling every freight car chassis to conform to the standard - well, I'm not even gonna go there."
Aint gonna happen.
"I understand the desire for these kinds of standards, and how much they would simplify both designing products and the modeler's ability to kit-bash easily. What prevents them from becoming reality is not coming up with a good standard, it is the complexity of implementing the standard."
I'm not so sure. Who decides what the standard is? Implementing it? You're kidding...right?
