Ntes app designed and maintained by CRIS and I have used this app from last few years and I have own experience that it Provides real time rail tracking system which have you can used to track your train and also you can marked as a fevorate train for view location at any time instantly also it provide train between system option where you can find number of trains with there timing also you can check cancelled train and diverted train. It provide live train under 2 hours and 4 hours also which is most useful for all passenger so I love this real time tracking app ie NTES app
