The probe into burning of a few compartments of the Deccan Queen and a Karjat suburban train during the violent protests in Ulhasnagar began on Saturday.
On November 30, Dalits in Mumbai and other parts on Maharashtra took to the street after a statue of Dr Babasaheb Ambedkar was vandalised in Kanpur.
The state government has set up a special inquiry committee headed by Additional Director-General of Police, Law and Order, Sanjeev Dayaal, to probe into the railway damages.
Dayaal visited the riot spots and walked a kilometre along the railway tracks from Ulhasnagar station to MP Gate in Ambernath.
"It is too early to comment on the inquiry," said Dayaal, adding that he visited the riot spots and got information about the incident from the local and the railway police.
He claimed that the police did not harass any innocent person. "If anyone has any such complaint he or she can forward it to me. I will see that justice is done," he said.
Dayaal also made an appeal to the public to help the police arrest the culprits.
"If anybody has any proof, documents or video shootings related to the riots, he should give it to the police. This will help in nabbing the culprits," he said.
"Arresting all culprits is important so that nobody will dare do such a thing," he added.
The city police have arrested 70 people and the railway police arrested 43 in connection with the violent protests in Ulhasnagar, he said.
The city police have registered 14 cases in connection with the Ulhasnagar riots and the railway police have registered three offences.
"The police have got hold of news channel reports with visuals and have also collected photographs published in newspapers," Dayaal said.
