National Rail Enquiries and trains entered in after they have started their journey

If a train is marked as cancelled in the National Rail Enquiries system but actually runs via a different route and is only updated to stay it is running, after it has started its journey, what happens?

Today the 7:35 Guildford to Waterloo via Cobham was listed as canclled. However it's now listed as running via Woking. For the stops Guildford; Worpolesdon and Woking it says no report. The first reported time is for Surbtion. Does that mean hmean it didn't stop at those stations or it did but as they entered the route in afterwards the system can't give a time?

The 7:34 is shown as running to Waterloo but starting from Guildford today, as opposed to Haslemere. South Western Railway say it was cancelled throughout. Times exist for that service though so I assume it stopped at Worpolesdon and Woking, after departing Guildford. Unless that became the other service on route. I find this kind of thing fascinating.

Just to add, I'm using the National Rail Enquiries App rather than Web Site. That may make a difference.

Two things from experience that could happened.

1. Different headcode entered at Guildford, meaning the train didn’t track.

2. Service was actually cancelled at Guildford but this wasn’t issued via Tyrell, (maybe forgotten to have been cancelled off) so it showed as ‘No Report’

As a side note, the app and website should get exactly the same data.

They should but I find when a train is stop is cancelled, it still shows on the app. So the other day Sandhurst was cancelled and then reinstated so it showed as cancelled and stopping. So two entries. Maybe it did the same on the Web Site but I didn't check.

Looks like the train started at Woking from the Bay platform, this corresponds with the previous working having terminated in the Bay at Woking. The correct headcode was definitely entered from Woking, so can only assume the alteration was entered after it had left Woking.
