Xbox Br Class 387 Pis Issue

An issue I’ve noticed with the PIS on the class 387 is sometimes it breaks, causing the destinations to register as “none” and on the outside of the train it says the train is stopping at “,,,,,,,,,,”

 

Do you know which services this affects? Does it happen while the train is moving? Is it AI trains, the one you drive or both?

 

Have you also noticed how the PIS also lists each unit as 3774XXX?

 

I was doing a run on great western express from London Paddington to Reading and it happened to my train
