After completing formalities, officials said, relatives of 12 victims took the bodies to Pakistan during the day.
A mini-truck carrying seven bodies left the Civil Hospital here at about 4.00 pm while another with five left at 8.30 pm.
All bodies, which were identified on Wednesday, were of Pakistani nationals. Those identified on Wednesday include Mohammad Harun, Farzana, Azam Khan, Zareena (all from Karachi) and Mohammad Rafiq (Multan).
With this, the total number of bodies identified has risen to 26, including one Harif Mohammed who succumbed to his injuries in Safdarjung Hospital in New Delhi. Among the identified, 20 are Pakistanis and five are Indians.
Sixty-eight people, including Pakistani nationals, were killed when two blasts ripped through the trans-border Samjhauta Express on Sunday night at Deewana, about 100 km from Delhi.
Most of the bodies that were brought to the Civil Hospital in Panipat, were charred beyond recognition, posing difficulties in identifying them.
Authorities have already made arrangements for embalming the bodies and for this, six teams of Army doctors are in the town. The team is led by Brigadier Amarjit Singh, Deputy Director of Medical Services.
DNA tests will also be conducted on the bodies and the relatives have been asked to get along with them at least one blood relation of the dead so as to help in the tests, officials said.
