You gave the scale guys at least 95% of what they wanted and gave us Hi-rail people a real treat.
With all due respect Francine, I don't think you understand the needs and desires of the "Scale Guys". The fact that the engine will not have scale wheels means that it will be of 0% interest to most scale modelers. It looks like a great model for Hi-Rail and AF modelers for sure, but scale modelers need scale wheels... Simple as that. Even if it means an aftermarket upgrade as with the Y3s.
Personally, I would prefer scale over Hi-Rail, but it has become painfully apparent that there will be precious little new scale product being made. Most of the scale modelers on the S scale Facebook group are saying that "S scale" is going back to its "scratch builder" roots. That doesn't particularly interest me.
Will people change from scale to Hi-Rail? Not sure. I suppose it depends on the products that are made. It is a real chicken-or-the-egg scenario...
