In a joint press conference at the CR headquarters here, top officials from both the divisions said the IRCTC database is in safe custody.
"Our preliminary reports have found no hacking nor any leakage on IRCTC ticketing website and everything is safe and going on smoothly," General Manager of Central Railway, S K Sood, said.
Railways has constituted a committee comprising IRCTC and Centre for Railway Information Systems (CRIS) officials on May 3 to check the possible theft of data.
The e-ticketing system is managed in-house by CRIS, the IT arm of Indian Railways. The data centre is on the premises of CRIS, headquartered in Delhi.

"Neither in Delhi nor here in Mumbai, no complaint or FIR has been filed. However we are cautiously looking into the issue," Malkhede said, adding the security system has been reviewed recently and they are still monitoring it.
According to Railways, the report of possible theft of data came to light on May 2 and a thorough investigation was carried out.
The data of e-ticketing system can be broadly divided into two categories - sensitive information like debit/credit card details, login ID, passwords, which could cause potential financial risk. PAN card detail is not required for booking e-ticket.
"No sensitive data have been leaked. Till now, leak of data through none of the service providers of IRCTC has been established," Ravindra Bhakar, WR chief spokesperson, said.
