Does anyone know of anywhere you can set alerts when tickets go on sale? I need train tickets for Taylor Swift concert in June. Are they likely to put on extra trains for this event? (A friend said they did for Ed Sheeran!) and are they likely to go on sale any earlier than the 12 week advance mark? I've set reminders to look for the tickets 12 weeks prior, but I'm worried I'll miss them as assume they'll be popular! Can't find any info online so thought I would ask here. I never travel by train so pretty clueless...
Thank you
