@Gaelan very cool!
if I may … the British Rail double arrow symbol only applies to GB, not NI, which is separate (logos attached, I prefer the old one)
(arrows trivia for those curious: it’s nowadays owned by the Department for Transport, and licensed to the Association of Train Operating Companies, branded as National Rail)
(it’s also arguable that in Scotland and Wales the logos of the national TOCs is appropriate? :o though these do still run under the National Rail branding so maybe not!)
@Gaelan (bonus: this image featuring two even older NI Railways logos, yay!)
