Toowoomba trainer Lindsay Hatch has had his best month on the track but believes he has had his biggest win off it.

Hatch underwent bowel cancer surgery on Tuesday and was hoping to be home by the weekend.

"They have a very good percentage success rate with the surgery these days. It apparently went well so I am looking forward to getting home," Hatch said.

"I will have to take it easy for a while but I have good family and staff support."

Hatch had his best day as a trainer when he prepared four winners at Toowoomba on Sunday - Rhyme Nor Rhythm, Helarocity, Jadentom and Captain's Way.

He has had five winners from his past nine starters with Transporter making a dynamic return to racing to win a 1600m-open handicap at Eagle Farm on January 21.

Hatch is proud of his effort with Transporter who won twice at Listed level and was third in the Group Two Hollindale Stakes before an injury enforced spell.

"After the winter carnival in 2014 he was injured and spent nearly two years away from the track. His owner Les Tinkler sent him to us to see if we could get him going again," Hatch said.

"We have a water walker at our complex and he seems to be loving life in Toowoomba."

The now nine-year-old will be having his second start this campaign in another open handicap over 1600m at Eagle Farm on Saturday.

"Emma Ljung who rode him to his first-up win is suspended so we will claim again with Rebecca Williams," Hatch said.

"I am hoping he is ready to fire again."

One of the biggest horses in training Transporter weighs about 600kg but Hatch hopes he can again show staying form.

"I would like to run him in the Toowoomba Cup. I don't know what weight he would get but it is a race which would suit him." he said.

Hatch was twice runner-up in the Toowoomba premiership before he decided to go further afield to gain more experience.

"They put a cushion track in at Toowoomba and I was against it. I took the family to Melbourne to work for John Sadler and then I was with Peter and Paul Snowden for 2-1/2 years at Darley," he said.

"It was great to learn from top trainers like them."

Hatch has been friends with top Brisbane trainer Tony Gollan for 20 years and when Gollan's father Darryl was in ill health Hatch returned to take over his stable complex.

"Also my boy is showing signs of being a top rugby league player and Toowoomba is a great place to bring up kids," he said.
