Nice, nice set. Makes me regret once again not springing for the Lionel Mohawk set.
On another subject, the too-big car spacing is one of my objections to Lionel's (and others, I think) new trucks/couplers. The coupler shanks are too long, the coupler cannot be adjusted if the knuckle won't stay closed, and they have a somewhat delicate coupler shank.
I know everyone complained about the "thumbtack" couplers, and everyone tried to improve theirs, but most are a step backwards in use ("where IS that blasted tab?") spacing, durability and maintenance. And those air hoses...that's where the tab is hiding.
(The hoses are easily snipped off.)
The thumbtack design, which was accessible, armature adjustable, short-shanked and user-friendly, needed finessing, not replacing.
