1. The ALERT button has a 1 second delay after pressing it on the Raildriver, bevor the alerter in the cab gets pushed. That is way to much. I have pressed it 2-3 times in panic that it didn't work bevor it starts to react. That's a perfect example on how not to do inputs. 2. The button to charge the brakes gets released after 2-3 seconds without releasing the button on the raildriver. I then have to release the button and press it again. Its a simple button, why can't you get that right?
