The whole thing around getting people into the ground is terrible.
There's no flow control in the Gallowgate so you have people queueing for the strawberry turnstiles while people are also need to get past for the main gallowgate stand turnstiles and it almost went into a crush yesterday.
The issue with the new tickets is it's slower to register the ticket to the turnstile, so let's say 2-3 seconds slower x 52k and you can see why the queues are bad.
