Metro Rail services were suspended for around half-an-hour between Dum Dum and Kavi Subhash stations on Tuesday evening, following a problem on the tracks, a senior official said.
Kabi Subhash-bound trains were stopped for 25 minutes after a spark was noticed on the tracks near the Rabindra Sadan Station around 6.50 pm, Kolkata Metro's chief public relations officer Indrani Banerjee said.
"A thorough inspection of the tracks was conducted and normal services towards Kavi Subhash resumed around 7.05 pm," she said.
On December 27, a fire broke out on board a metro train here during rush hours, causing a stampede-like situation and leaving at least 16 passengers injured.
