stick lock

[onestrangeday]

thanks PJW, I have now gained better understanding on the subject.

Not used on the IRSE suggested CT which has a column for the route locking but nothing explicitly for stick disengagement.

If the CT has entries for a layout included then if
a) for stick disengagement: there would be the ID of the TC OCCUPIEDimmediately beyond the relevant signal (possibly also with berth TC also occupied)
b) for opposing route locking: then there would likely be several rows of entries, each consisting of a sequence of TC IDs required CLEAR, which start at one of the opposite direction signals and listed in the order approaching that of the signal which is the subject of the specific CT.

Hi PJW:

thanks for your reply. I saw this on the control tables where it has this heading at one of its column. So do you have any ideas when will 'stick locking' be applied into the design of interlocking systems?
thanks

Not a term with which I am familiar; what was the source which used it and the context.

It could be something else such as a "route lock stick" used to impose maintained locking on points & conflicting routes after a train has been routed past a signal........

Hi Signalling Professionals:

Recently, I came across a signalling terminology "stick lock", can anyone define what does it mean ?

and in what situation would the "stick lock" be applied in the signalling design ?

thanks
