AWS TPWS Self Test

When a train cab is energised, the Automatic Warning System (AWS) and Train Protection and Warning System (TPWS) undergoes a self test. The test is completed as follows:
- Check all lights illuminate on the TPWS panel
- Ensure AWS warning tone (horn) can be heard
- Observe AWS visual indicator is all black
- Acknowledge with AWS/TPWS acknowledge/reset button
- Ensure AWS warning tone (horn) is replaced with a clear tone (bell)
- Observe AWS visual indicator is black and yellow
- Observe all lights on TPWS panel extinguished

Funny enough, it always feels weird to me hearing an AWS self test without the Mk4 announcement made nowadays 🤔

Of course it would it does that on every train

[@Panda1303]

Nope, it doesnt. Some trains, like the IETs (Class 800-810) have different sounds. @@FormerleyMonsterJamFan

[@FormerleyMonsterJamFan]

@Panda1303 I think you're thinking of the AWS yellow aspect. It sounds the same on green signals

[@Panda1303]

@@FormerleyMonsterJamFan Nope, even the clear sound is different.
