Trainer Gino Poletti was thrilled with the hit-out.
"Shaun (O'Donnell, jockey) said he felt terrific," Poletti said.
"He was very pleased more so with his relaxed nature and the most important thing was he got a dead 5 track.
"We might run in to some wet tracks over there.
"The hardest thing was holding him back and not over-training him.
"I'm not sure how he'll travel so he won't gallop again until Tuesday week."
Luckygray won last year's Group 1 Railway Stakes on protest over He's Remarkable.
He took all before him in a short autumn-winter campaign at Belmont with wins in the Roma Cup, Belmont Sprint and Hyperion Stakes.

"We bred him ourselves," trainer Phil Humann said.
"He's always shown a bit of ability and has to be ridden back in the field.
"He'll go on to a 1400m race in a fortnight."
