Joe Lyons,
Steve is correct about the 263E train sets the 800 series rolling stock were the 1st cars that came on the original 263E, which included the big 810 Crane Car, later these Cars became the 2800 series rolling stock. The 260E came with both 800 and later 2800 rolling stock also. I would need to review the 261E & 262E Train Set to see exactly which rolling stock, 1st came with those trains sets, not sure of the sizes of the 261E & 262E engines and tenders off the top of my head. I do believe the 262E is the smaller engine & tender, in the 259E size range. I do own the original Lionel 259E & 264 train sets, both originally came with 2600 series rolling stock, however the 264 is the mid size Lionel Tin Plate, engine & tender, between the 263E and the 259E Train sets.
