I posted elsewhere that the leases on the old machines had run out and the hardware was considered life expired, and that the Shere machines were/are all going.
I've seen the new machine at WGC and found it odd that they've got vinyls stuck on that look badly sized and cut out, a weird duplication of the 'Tickets' text, graphics that don't line up to things on the machines, and a barcode reader that is given undue prominence - considering nobody seems to know what it's for.

I do think the software is okay though, especially for managing railcards and adding/subtracting adults and children, or editing things before purchase - but it really does need to be updated to sell tickets from another origin, and to do boundary extensions.
Do that and I'd have few complaints. The fact they take CPCs massively speeds up purchasing times.
