Road trip:
My local Division 7 (Cincinnati, Ohio) of NMRA has a one day bus tour of local (within 150 miles, or so) railroad interests.
This year we saw two On3 layouts, a club (50'X150') and a very cool full size 'age of steam' roundhouse.
The 'age of steam' is not open to the public but they allowed the NMRA a tour. A fully functional roundhouse with pit, about a dozen steam engines, about 20 diesels and all kinds of cars. One person owns it and has a working crew doing repairs, etc.
The roundhouse is the only one built in the last 60 years. With such tremendous weight, I beams had to be driven down to bed rock (60') to support the turntable and wooden beams to support the roundhouse.
Very cool.
Some very nice scenery on the On3 layouts.
The large club layout has an actual interlocking tower 'armstrong' controls that move the turnouts on the one section of the layout.
