The behavior of the E-stop button on all cabs is based on which command station is being used.
The E-stop button when used on the Power Cab and SB5 systems is single loco only regardless of which cab triggers the E-stop. This is different from the multi stage / full layout shut down E-stop on the 5amp Ph-Pro / Power Pro or CS02 system.
The "Big Red Button" on the Power Cab and Pro Cab throttles does a few different things. Again this is based on which system it is being used on.
1. On all systems: Press this button once to stop the current locomotive selected on any NCE system but leave the speed setting intact.
2. On a CS02 / Powerhouse Pro / Power Pro system ONLY: A second press will reset the loco to 0 speed.
3. On a CS02 / Powerhouse Pro / Power Pro system ONLY: A third press will shut the entire command station down and turn off track power. The full system wide Estop is only available in the PH Pro command stations. To re enable track power the system must then be turned off then back on again.
The Estop in the Power Cab and SB5 is a single key press for the current locomotive only.
While in Radio mode the red Estop button also serves as a power "on" button to turn on the wireless / battery operated throttle.
