Chris Waller has been encouraged by Damien Oliver's decision to stick with Triple Honour in Saturday's Kingston Town Classic in Perth after his last start disappointment.

Triple Honour beat just one runner home in his first West Australian start in the Railway Stakes (1600m) but his Sydney trainer said he would give him a chance at another Group One this week.

"On face value it was disappointing," Waller said.

"But the race was run at a slow tempo which didn't suit him and the step up to 1800 metres is in his favour.

"And Damien is keen to stick with him which gives me confidence he can do better."

Fellow Sydney horse Black Piranha also failed in the Railway with his jockey Daniel Ganderton also citing the tempo as a reason.

"It wasn't an outstanding run but I think the run was better than what it looked," Ganderton said.

"The way the race was run, there was no pace, he was given no chance with his big weight (58.5kg)."

With Railway winner Gathering out of the Kingston Town, emerging local star Playing God was installed as favourite following his comprehensive win over his fellow three-year-olds in Saturday's Aquanita Stakes (1800m).

He will clash with his year older full brother God Has Spoken.

Playing God has built an impressive record of four wins and two placings from just eight starts for earnings of more than $309,000.

"They'll both run and both will be excellent chances," trainer Neville Parnham told perthracing.com.au.

"Obviously the three-year-old with the (light) weight he will be carrying - he'll be the favourite (between the two).

"But at the end of the day it will be a good contest."

A field of 16 was declared ahead of Tuesday's barrier draw with Triple Honour and Black Piranha at $18 and $21 respectively with TAB Sportsbet.

Playing God was still the $4.60 favourite when betting re-opened on Monday.
