Opponents of the HK$66.9 billion express rail link to Guangzhou are planning to mobilise university students ahead of Friday's delayed vote on funding.
However, the government is determined to put an end to the funding row before protests escalate.
The Transport and Housing Bureau has asked the legislature's Finance Committee to set aside three days for a marathon discussion - from 3pm to 11pm on Friday, and 9am to 9pm on Saturday and Sunday - until the committee reaches a conclusion.
The government's demand, which is awaiting a reply from the committee chairwoman, came as opponents of the link planned to recruit supporters from six universities.
'We will host a series of activities outside the Legislative Council from Thursday, including a music concert like that at Woodstock,' protest organiser Bobo Yip Po-lam said. 'We hope youngsters will learn more about the problems of our flawed political constitution.'
Crowds gathering outside the Legislative Council building have increased since pan-democratic lawmakers successfully delayed funding for the link twice since December.
However, even lawmakers opposed to the link say they may not succeed in stalling funding again this time, especially with their allies in the Democratic Party leaving them to decide on their own action.
