Xbox Aws Slamming Brakes

Hello
Can any one help me with the Midland Mainline DLC? Whenever, I'm pulling into Derby or Nottingham, driving the Class 158, the AWS slams the brakes on, out of the blue, without a reason or alert for me to press anything. Is this a bug or am I doing something wrong?

If anyone could help, that would be great.

 

Its not AWS, its TPWS. It has decided that you are driving too fast for the situation. Usually it is because you are approaching a red signal or reduction in speed limit faster than it thinks is safe. Slowing down faster in those situations stops it happening to me.

 

At Nottingham I find that if you are below 25 by the signal gantry you'll be fine.

 

Oh right. I didn't know TPWS could do that. Thanks mate!

 

I'll stick to a lower speed limit now. Thank you

 

That's alright mate, glad I could help.
