A long time ago, BAET once posted some information about how remote securing worked in pre-SER days, with lots of lovely circuitry info and diagrams and stuff - he used Queens Park (BB) as an example of how remote securing worked.
Are the principles of remote securing the same in modern SERs (i.e the Central and Jubilee SERs)? I do know that the sites lucky enough to have full lever frames (OZ, OP, EN, JB (part), JP (part)) are able to use the route card procedure, based upon the failsafe point indicator circuits in the frame, but how is similar information conveyed in SER-land?

Did I?? Queen's Park was the probably the only place I had the circuitry for, though ISTR using the standard reference sheet to explain it.
It is different on the Central, but I don't have any circuitry to refer to right now. Give me a few days to get back to the UK (currently in Igelkotten-land).

As far as I know you gave out lots and lots of technical info, including acronyms. I can't recall if you posted any diagrams but you definitely described some of the circuits used. It is different on the Central, but I don't have any circuitry to refer to right now. Give me a few days to get back to the UK (currently in Igelkotten-land). Thanks. |

BUMP.
Now that BAET should be back from the Land of Hedgehogs, could you describe (again) how remote securing works, and additionally, which sets of points at a site are likely to get it?

Notes are at work - will retrieve them tomorrow.

Notes are at work - will retrieve them tomorrow. Thanks. All I remember regarding remote securing is the 'route card' procedure used at sites with manually operated lever frames and primary-circuited point indications. When was the 'route card' procedure invented? |

The Route Card procedure was, as far as I can remember, introduced on the H&C/Met in 1995/6. I remember being the one who wrote out the cards for the Edgware Road area, and also assisted the chap at Hammersmith.
