Tram passengers will enter vehicles from the front under a $1 million refurbishment plan to be completed by March.
All turnstiles will also be removed to allow travellers to get off at the rear.
Staircases to and from the upper deck will also be widened as a safety measure and closed circuit video systems and a rear door alarm will be installed to ensure passengers have got off before trams leave a stop.
Hongkong Tramways general manager, Frankie Yick Chi-ming, said the changes were being made to enhance safety and smooth passenger flow on the crowded vehicles.
He said five trams were being refurbished now and work on all 161 vehicles would be completed by March.
'We have decided to use the same method as the buses do as it will help to streamline the flow of people,' Mr Yick said.
