Xbox Series X East Coast Way, Class 171/8, Service 1g06 Signal Issue

Tried 3 times on service 1G06, 07:45 service from Ashford international to Brighton, with class 171/8.

Everytime i got to signal T700 on the viaduct heading into Brighton, it shows a red with 2 white dots, so it should be clear to proceed, everytime i go through i get a spad.
I have taken step by step pictures

So yeah cant finish this service.

 

Press "Train Stop Override" before passing the signal, then drive past it while the button is lit.

 

Cheers for the assist bud. I shall give it a go, and se eif it works ok. Shall let ya know.

 

Hi bud. Just did what you showed me.
