Objective: Currently, the user is rely on the results of the Google search i.e. lengthy documents, web links etc. So, Question Answering (QA) dialogue system becomes more vital to access the succinct answers in a jiffy. Methods: The main focus is on Query Processing based on partial semantic and syntactic analysis and keyword based approach. The major module is Dialogue Manager which is responsible to communicate between the User and the System to resolve anaphora and Co-reference problems. Findings: The existing Indian Railway system is based on clicking system which is more time consuming. Thus, proposed QA dialogue system provides specific and concise answers to users. The results are encouraging and a motivation for further research in this field. The proposed system restricted to provide answers of related queries but further extension of the system can also include replies related arrival time, departure time over the phone etc.
