    I am trying to use the EMT HST and I can't find any AWS switch. I have looked up and results say one of the two switches over the fire suppression discharge box but these are vigilance and DSD, none of which enable the AWS when set to normal Other results say one of the three switches next to the lighting switch, these are a spare switch that does nothing, demister, and clipboard light. None are for AWS switch. Where is the switch to enable the AWS?

    It’s on the second man side on the cab, near the DSD switch

    In the HST's files, the Spare switch is linked to the AWS isolation, but I don't know if it actually does anything yet

    There is no AWS on, I am supposed to hear it om approach to any signals even if they are clear but it does not do anything.

    The switches on the secondmans side are DSD and vigilance . It does not have one for AWS there.

    I tried it on and off but it makes no difference.

    without using any switches and just setting off AWS does work for me, the keyboard shortcuts only toggle DSD and Vigilance with nothing for AWS

    I think some of the buttons may have been incorrectly named, DSD Isolation seems to actually be the Vigilance Isolation, and Vigilance Isolation is actually AWS Isolation. I tested it on East Coastway and AWS seems to work fine with Vigilance Isolation set to Normal

    DSD meanwhile doesn't seem to work at all

    I thought it didn't work as I accidentally stood up once pressing E when the vigilance went off (TSC move), but I don't have any AWS. I was on Edinburgh - Glasgow so I should have working AWS.

    Im also quite sure its the vigilance switch, left of the dsd isolator switch iirc.

    It is in the "normal" position but there is nothing from the AWS.

    Very late reply, but I was interested in this myself and found this post! After some experimentation, if you keep 'Vigilance Isolation' in the isolated position, that enables the AWS. 'DSD Isolation' in the normal position seems to enable the vigilance! Clearly some unfortunate mislabelling, but hopefully it works for you.

    For that train, I usually cycle all safety system switches off and on twice and then everything works
    It is like... 50 years old after all! ;)
