Aws Button On Xbox Controller

Can any body help with which one on the X Box controller is the AWS acknowledge button tried a few but still cant find. Thanks in advance.

 

Press the B button. Needs to be activated by finding finding the AWS lever in the loco.

 

B button when using TSW 2020 the Classic Controls and immersion controls. AWS switches need to be activated on the locomotive/EMU. For Electrostar EMU it's on the right side of the cab

 

It’s the B button the same as for DSD a knowledgement

 

thanks all
