Good Project will take on local star Scales Of Justice again in Perth but will also have strong opposition from within his own camp when he lines up in the Kingston Town Classic.

Scales Of Justice led all the way to deny the Chris Waller-trained Good Project back-to-back wins in the Group One Railway Stakes.

Sydney's premier trainer will have three runners - Good Project, Mackintosh and Vanbrugh - in the Kingston Town on Saturday, the final Australian Group One race for the year.

Waller said there were no concerns with Good Project who was reported to be mildly lame after the Railway.

"He lost a shoe, that was all," Waller said.

"He had a strong gallop on Saturday morning and all three horses will be suited by the 1800 metres.

"And Vanbrugh is the fresh horse on the scene."

Vanbrugh hasn't raced since his midfield finish in the Group One Emirates (2000m) at Flemington on November 5 when he struck trouble inside the final 100 metres.

Before the Emirates, Vanbrugh showed he was back in form with victory in the Group Three Coongy Cup.

Mackintosh finished fourth in the Railway after a Group One fifth in the Cantala Stakes at Flemington won by Le Romain.

Before the Cantala he won the Theo Marks Stakes then finished third in a three-way photo in the Epsom Handicap.

Mackintosh is the most favoured of the trio at $9 with Good Project $11 and Vanbrugh $13.

While the Kingston Town is the last chance for Waller to add to his 2016 Group One tally in Australia, the trainer is eyeing off an elite level win across the Tasman with Lady Le Fay.

"She won't run in the Pakenham Cup this week and she may even go to New Zealand for the Zabeel Classic at Ellerslie on Boxing Day," Waller said.

Lady Le Fay did her early racing in New Zealand for trainer Paul Shailler, foreman for Waller when he first came to Sydney.
