Mumbai's special Maharashtra Control of Organised Crime Act (MCOCA) court on Friday convicted 12 of the 13 accused in the 2006 serial train blasts case.
The court is likely to announce their sentence on Monday, 14 September.
Abdul Wahid Din Mohhamad Shaikh, accused number eight in the case, was acquitted.
Special MCOCA judge Yatin D Shinde who had finished the trial in the 7/11 Mumbai train bombings on 19 August, 2014, pronounced his verdict over a year later.
At least 188 people were killed and 829 injured when seven RDX bombs kept in seven first-class compartments of Mumbai local trains on various stretches went off on 11 July, 2006, PTI reported.
The bombs kept in pressure cookers on the north-bound trains exploded at or near Khar Road-Santacruz, Bandra-Khar Road, Jogeshwari-Mahim Junction, Mira Road-Bhayander, Matunga-Mahim Junction and Borivali in a span of 11 minutes.
Maharashtra Anti-Terrorism Squad (ATS) had arrested the 13 accused between 20 July, 2006 and 3 October, 2006. They questioned as many as 250 defence and prosecution witnesses, The Indian Express reported.
The special MCOCA court found them all guilty in the serial train blasts case on 6 August, 2007.
