Commuters using the Downtown Line 2 (DTL2) to get to work yesterday morning found that there were delays on the new line.
Mr Zhi Cong, 23, said the train he boarded at Bukit Panjang did not move out of the station for about eight minutes.
"After the train reached Sixth Avenue, it was stuck again for another eight minutes," said Mr Zhi.
Lawyer Lyv Meah, 37, said the platform doors failed to open at Rochor station, causing a delay.
She added that the train she was on moved "slowly and jerkily" towards Bugis after the problem with the doors was rectified.
SBS Transit's senior vice-president for corporate communications Tammy Tan said that slow service on the line was caused by a signalling fault at Rochor station at 9.10am yesterday. "The fault was rectified soon after and trains could resume their regular speed at about 9.18am," she added.
The DTL2 was officially opened on Sunday, covering a distance of 16.6km from Bukit Panjang to Chinatown.
In a blog post made on Dec 21 before its opening, Transport Minister Khaw Boon Wan said that commuters could expect "teething issues".
He added in his post that engineers from the Land Transport Authority and SBS Transit had
told him that there would be a 'bedding-in' period of several months for the DTL2 before it stabilises.
