The MTR Corporation says services on its Kwun Tong line are back to normal, after delays due to what it said earlier was the improper use of train facilities at Yau Tong Station.

Journey times between Whampoa and Tiu Keng Leng Stations had earlier been extended by up to 20 minutes. It had advised passengers to consider using other transport, and long taxi queues soon formed, particularly at Yau Tong station.

Earlier, the MTR said all other train services were operating as normal, after almost 50 stations were closed yesterday due to vandalism by protesters.

It says some station exits may be closed while they’re being repaired.
