Theres at least 2 Ayats in Belfast for that service 2019 AXI 319 and 2023 BXI 323. They are probably not being used to their full potential as there may be some training issues to resolve.

Derry has 13 of the new type Ayats and the original (2001), expect to see them making guest appearances in Dublin very soon.

2019 was in Dublin today as I passed it on the Balbriggan By Pass.
