Interesting that many will dismiss the Lionel cars for incorrect windows but overlook the fact that no one else except GGD has full width diaphrams which were an early trademark of the Daylight to make it appear to be a continuous train with no breaks.

Pete, I honestly don't think there are that many folks dismissing Lionel for the window issue. Frankly, I never heard of it until Nick clarified a comment on another thread.
I would however agree that GGD has top of the line models if one is looking to purchase the absolute best in O-scale passenger cars. I saw the GGD Congressional set that The Public Delivery Track brought to York last October, and it was magnificent -- definitely in a league of its own.
