My question relates to tms/voice announcements system Did the short TP15 service Edinburgh to polmont and at Edinburgh no stop was announced for haymarket looked at tms screen and realised destination blank so I changed it from blank to polmont then when I repeated above step got we will soon be arriving at Linlithgow and this got me thinking is it the case that the audio announcements are linked to the destination display rather than timetable itself as seems odd destination was blank and not displayed when started service at Edinburgh itself would be intresting to learn more/people’s thoughts on this please
