PC Traction Blocked In Acs In Nec

Hi,

I have just enabled ATC and ACSES in the ACS-64 at the start of a service run in the station. When cleared for departure, I began to proceed as I could see the next aspect was clear. However, when I began to drive, I noticed I could only crawl at 2 MPH regardless of the power control being at 80%.... On the Driver HUD I also noticed a red alert saying "traction blocked"... Does anyone know why this happened?

Is there something I missed on departure?

Thanks
Arm

 

Doors closed? All brakes released, train AND loco brake?

 

Yep I'm sure ... Independent, automatic and air brakes all off ... Doors closed

 

Can you make a screenshot, best with both displays visible so we maybe can see what's wrong.

 

same issue here but I got the alerter cutoff as well but in the city sprinter scene
