22 Radius works great for longer passenger cars!
We set up dad's trains for special events at his assisted living facility (that's him in the photo provided.) He has a commemorative NMRA HO scale train with very long passenger cars that couldn't negotiate the 18 Radius track that comes with the Bachmann sets, so we bought the 22 radius to use with that train, and it works GREAT! Dad has lots of cool track that he made himself over 60 years ago, but it's complicated and tricky, and doesn't really work well for tempoorary set ups. I help dad set up each time, and the Bachmann EZ track makes it fast and easy, I can set up a huge layout in a few minutes, and dad has a GREAT time running his trains - and the other residents love it!
