Conservatorium has played his part in a long-term plan to win the Group One Railway Stakes at Ascot on Saturday.

Since Conservatorium finished fifth in last year's Winterbottom Stakes at Ascot, the father-and-son training team of Gary and Lloyd Kennewell have targeted the $1 million Railway for their the six-year-old.

They knew they were on the right track when Conservatorium was edged out in the Listed Centenary Mercedes Benz Mile by Fire Up Fifi, also a Railway acceptor, at Eagle Farm in late June.

That was the first time Conservatorium had run 1600 metres and his performance that day sealed his start in Perth.

"We had got to the stage where we thought he probably couldn't get past 12-to-1400 metres but we tried him in the mile in Brisbane and he was second by half a neck to Fire Up Fifi," said Gary Kennewell.

"He carried 60.5kg that day and that gave us the confidence we could head over here for the Railway."

For good measure, Conservatorium picked up the Lee Steere Stakes to more than cover expenses for his Perth campaign.

At Ascot, Conservatorium will carry 56kg, and with the emergencies out, will start from barrier eight which Kennewell said is the perfect gate for the front-running galloper.

"If there is good pace going all around him he can sit back off them, or if they are going steady he can go forward and take up the position there - it's all pace-related," Kennewell said.

Kennewell said the $14 chance has improved since his Group Three Lee Steere Stakes win on November 9 and expects him to run well in the Railway.

"That was the plan - to get here early and try to knock off the (Lee Steere Stakes) that was a bit easier," he said.

He will wait and see how Conservatorium pulls up before considering running him the Group One Kingston Town Classic (1800m) on December 7.

Joe Bowditch will ride Conservatorium, as he has done in the gelding's last 12 starts.

"He's never ridden a bad one on him and, hopefully, he doesn't start on Saturday," said Kennewell.
