    I am trying to drive the GWG HST but after 1 minute or so at 15mph the brakes are applying, after waiting 2 minutes timeout it still will not let me apply power but if I disable safety systems in both power cars I can release the brakes again but not apply power. I noticed in the back power car the TPWS brake demand light is now on, if I set up the rear cab and wait the two minutes it does not go out. How am I supposed to reset this and stop it from keep happening every time I use the HST?
