FYI:....A fellow Forum member who I believe was NP2626 sometime ago asked a question about the plastic shield surrounding the NMRA Standards Gauge. The plastic snap on shield is the standards clearance gauge for tunnel portals for rolling stock since 1983 when double stacked and high rolling stock made its appearance and higher clearances became necessary.

When the plastic shield is removed the NMRA Standards Gauge can be used like most have become accustomed to using.

Thanks for letting us know. I had no idea that the sheet metal stamped gauge also came with an adaptor for double-stacks. Makes sense, and I heartily agree with the concept.

Turns out I don't need it. My gauge is this, Trix HO, but with the pantograph raised. I need 4.24" overhead for this one locomotive:

I used an On30 Forney to accomplish much the same purpose , the only piece of On30 that I have, lol
It was easier to use than the gauge, I have two or three of the gauges, I keep misplacing them...
