I just tried a run in the 377 from Brighton to London, and the AWS was very buggy. I first noticed that I wasn't always getting the ping when approaching a green signal. But I then also started randomly not getting getting the alert tone when approaching a distant signal at caution. Some worked, others did not. It ended with an emergency braking near Victoria because I overlooked a magnet (there was no caution sound) and got stopped. Anyone else noticing this?
