Leading trainer Annabel Neasham will face further questioning over the circumstances which led to four of her horses being released, including one that made it as far as nearby Warwick Farm train station.

CCTV footage of a racehorse on the platform at Warwick Farm railway station after escaping from trainer Annabel Neasham's nearby stables.

The much-publicised escapee made national news bulletins on Thursday when CCTV footage emerged of the horse trotting along the train platform around midnight last Friday night.

The horse avoided injury in the incident, which saw a train arrive on the platform as the horse was moving alongside. The train kept its doors closed when stopping, and the horse was recovered by Neasham's staff and returned to its stables.

Neasham told Racing NSW stewards that an unknown person gained access to one of her stable barns in the Warwick Farm stabling precinct.

She said the person released three racehorses and a stable pony. The one captured on the CCTV footage was the only horse to leave the stable.

Neasham, who has one of the largest stables in the country, said she contacted local police who attended soon after and the horse was recaptured.

Stewards reported their discussions with Neasham but said that she will be formally interviewed at a time to be fixed regarding the incident.

The horse in the video has not been identified.
