Local trainer Adam Durrant has pulled off a training coup to win Perth's richest race with Mr Moet claiming the $1 million Railway Stakes at Ascot at his first start since July.

Mr Moet burst from the ruck inside the final 100 metres while last year's winner Luckygray made a sustained run down the outside from last on the turn but came up three-quarters of a length short.

Many punters had faith in Durrant's plan, with the TAB reporting a steady stream of money for Mr Moet at $101 early in the week and again on course on Saturday where he was backed from $31 to $21.

Durrant sent the five-year-old, who has scored six of his 10 wins at 2000 metres and beyond, into the 1600m race with two barrier trials under his belt and said he was almost speechless with the result.

"I'm very humbled, very proud of the horse and the staff," Durrant said.

"The Perth cup was on the cards for him if this didn't work out but I knew we had the horse to do it.

"He's a great horse fresh and lethal if we get him right.

"And I took a little bit of the 150-1 that was around early on."

Durrant praised Daniel Staeck for his ride but the jockey said he knew he had the right horse underneath him.

"It was a bit easier than expected without sounding cocky," he said.

"Adam gave me a fair bit of confidence before the race and I knew I just had to get him into clear running."

Wall Street (eighth) finished best of the eastern states visitors with Epsom Handicap winner Fat Al and triple Group One winner Yosei among the tailenders.

Earlier, unbeaten sprinter Barakey stretched his tally to 11 in the other Group One of the day, the Winterbottom Stakes (1200m).
