Thameslink: "formed of" Vs "which has"

[Tobberz]

Thameslink announcements now seem to say "a Thameslink service which has x coaches", whereas I'm sure it used to say "formed of X coaches".

Am I amnesiac, or has it changed?

And, further, is this part of this premise of the supposed de-lingoifying of the railways, e.g.: abandoning use of the word "terminating"?

For as long as I can remember in Northern land, the displays have said "A Northern service which has 4 carriages", but the wording of the announcements has been "This train is formed of 4 carriages".

Is this onboard the train itself or at the station? If it's the latter, what station did you hear it at?
