Public transport operators are boosting services to accommodate the large crowds of passengers expected during the Hong Kong Sevens tournament.

The three-day event at the new Kai Tak Stadium started on Friday.

The MTR said it was increasing the frequency of trains on the Tuen Ma Line and deploying more staff than usual at Kai Tak and Sung Wong Toi stations.

Citybus and KMB, meanwhile, said 11 special routes would be in operation at the end of each day of the tournament.
