It's very odd that Lionel would make this set of heavyweights that don't have colors matching the Vision GS locos. Having an engine pulling cars with colors that don't match is not a good look. For heavyweight passenger cars that match, the ones to get are the No. 25506 (the 4-car set (there was also a 2-car set and sounds diner), cataloged in 2008. For matching aluminum streamlined Daylight cars, No. 29115 (the 4-car set, again there was also a 2-car set and sounds diner) cataloged in 2005 are the ones to get.
