One such dynamic change taken place in India is in the area of transport, especially rail travel application started by Indian Railways, namely, Indian Railway Catering and Tourism Corporation (IRCTC) portal.

Data from 193 usable questionnaires was collected from Goa and were tested against the research model. Result indicated that habit, hedonic motivation, performance expectancy, and perceived trust were the main predictors of behavior intention to adopt and use IRCTC application. The proposed model was able to explain 65% variance on behavior intention.
