A dog entered train tracks near Mong Kok East train station on Monday, causing delays on the MTR East Rail line at around 8am.
The MTR warned at 8:07am that trains may be delayed for around 10-15 minutes.
The situation was resolved by around 8:40am after five staff at the station used a sheet of canvas to drive the dog from the tracks. Service then returned to normal.
Trains going through Hung Hom and Mong Kok East stations slowed down during the 40 minute standoff. The incident caused congestion at East Rail stations as crowds swelled during rush hour.
In August 2014, a dog which also entered the East Rail Line tracks, was killed after failed attempts to remove it. Although trains were suspended momentarily, the control centre decided to resume services and the animal was hit by an intercity train from Guangzhou.

The incident sparked outrage and lead to a re-examination of MTR Corporation policies.
