Is this actually possible

Hey all

https://www.realtimetrains.co.uk/service/gb-nr:W33954/2026-09-10/detailed#allox_id=0

Really? Is a 20-car Pendolino actually allowed to run in public service? I only met with my supplier Avanti today - could've asked the rep had I seen this earlier!

There are multiple threads on the same topic, no, it didn’t happen, it’s an IT data error. Usually when two sets swap and someone forgets to delete one of them on the new service.
https://www.railforums.co.uk/threads/rtt-showing-a-20-coach-pendolino.293280/ is just one previous example. Or https://www.railforums.co.uk/threads/22-coach-pendolino.290852/

It's been updated to 11-car on RTT but the guard is saying 9-car despite us being 137! Curious and curiouser
