@OGRNorman, I agree with @TM Terry 's post above. At 1/24 scale, the LGB/Aster Hudson is a bit too big for the train if that's really a concern.
This may or may not help, but here's a picture of Lionel's Commodore Vanderbilt Hudson pulling a train of State cars -
Overall, it looks pretty good, but the engine is actually a little small for the cars. From the perspective of size, it would be better suited to the Blue Comet cars on the inner track. Of course, the 400E Blue Comet locomotive is really too big for its cars and is better sized to the State cars. Go figure . . .
Height and width wise, the State cars are actually better matched to my USA Trains 1/29 scale Hudson. Unfortunately, I haven't got a picture to share at this time.
Cheers,
