Yes, it's G gauge. One of the most captivating G gauge indoor layouts I've visited is EnTRAINment , Exit #22, off of I-71. Floor to ceiling scenery in three time periods. Civil War, WW II, & modern. Worth the stop coming back from the USAFM at Dayton, Ohio. Just returned from the children's Museum in Cincinnati with the Grandson & Family. Small G gauge layout in the lower floor and AWESOME display of prewar Std Gauge & O Gauge trains filling many shelves. Full size operating Carousel on the top floor. Yes...We all took a ride! Worth a visit! Many spectacular operating layouts in different gauges around the Country. I even have a few vids on Youtube.
Have a great week, stay safe & "Tight Lines!"

P.S.; When it's nice outside, I fly planes!
When it's not, I run trains!
