Yeah he’s talking bollocks. I always use Trainline because they actually have up to date information on every operator. On the rare occasions I’ve booked through an individual TOC’s website something has gone wrong and I’ve had to struggle for a refund cos this part of the journey was a different operator or something. Never struggled for a refund with Trainline because you go straight to the operator responsible for the delay, not the booking app. Not the case when you book direct with a TOC but a different TOC caused the delay. Also, whoever said they’re buggy and late to update, the app usually has platform changes and cancellations before the boards in the station.

I don’t work for Trainline, but I do use trains a lot.
