"Service Approaching"

[miata54]

I find this message very annoying when it appears as I near another loco. Just wondering if anyone knows how to disable it or even where the file is located, or its trigger?

Thx

As far as I noticed (I never play freeroam, excepting for testing purposes) It appears only for driveable engines approaching (in freeroam) to give the driver a chance to change loco, and goes on in few seconds (15 secs I guess). It's a deep scripted feature to any freeroam, don't know how to change it.
