Hi,
I’ve come across the following in Network Rail standard SSI/8500/D(1), section 4.1 “Motor Drive Outputs”. The section details the motor drive outputs of points object controllers for SSI.
“A motoring up facility is also provided in the Module which operates in the event of detection loss without any change in the points control command from the signalling.”
So I’m taking this to me that in event that detection is lost without a command from the interlocking the points machine redrives the points to regain detection with no additional command to do so from the interlocking. I have a few questions about this:
Does it do this even if there is a train in section or even on the points?
What is the history behind this, is there an incident which occurred that meant this had to be introduced?
Where the points machine is not controlled by SSI is this function still present?
Many thanks for any help you might be able to give with this issue.
