“The latest feature we’ve added, which is only available on the app is the ‘Running Status’ option.

The probability of a ticket being booked is presented using a colour-coded percentage — tickets with odds above 65 per cent are highlighted in green, which implies a high chance of the ticket getting confirmed. Tickets with sub-optimal odds are highlighted in yellow (50-65) and red (below 50 per cent odds). Trainman has been tested with over 5 million PNR numbers, and claims an average accuracy of around 83-90 percent.
