When looking through some NX panel photos (e.g. https://photos.signalling.org/picture?/25896/category/3297-2017_march ), I'm struggling to work out the purpose of the central indication lamp on the point switches. The N and R lamps I presume are lit when the points are detected in the respective positions, but the central lamp isn't as obvious. From the photos on the linked site, as far as I can tell they don't indicate that auto mode is selected, nor do they indicate that the point is free to move.

I'll open with I think the Western region E10K panels work differently with how the indications work, I'll leave it to someone else to answer how they work. N lit - Detected Normal R lit - Detected Reverse C lit flashing - Points are out of correspondence. [EDIT] Actually I think flashing means the points are out of correspondence (Should be normal but are reverse for example), while lit steady is that they aren't detected in the position they currently lie in. It's been a long time since I signed Gatestown  The switch itself needs to be in the C position to allow route setting to call the points automatically to the needed position. If you move the switch to N or R you'll only be able to call routes that require those points in that position.

Minor footnote: The C will also flash when the points are moving as they are not detected in either position when moving of course. If it continues to flash you've got a bit of a problem :P Of course some particular designs of panel may function differently?

You're quite right of course. Not too far off Power Operated Points on the block shelf really, white N if they're normal, white R if they're reverse, Solid white if they're in anyway unhappy. Except the solid white doesn't come up when they're travelling between positions.

The C light on at least one brand of panel point switches lights up if the point is locked (eg route or flank). As you can see, there is no single standard! SimSig Boss Log in to reply The following user said thank you: Steamer |

The centre red light on on WR Panel point switches is indeed a lock light Out of correspondence is indicated by the route lights on the panel flashing alternately between Normal and Reverse Log in to reply The following user said thank you: Steamer |

At Derby and Trent where I worked the centre light would flash while points were moving and would stay flashing if no detection was found, i.e. out of correspondence.

Some panel fascias have a fourth light above or below the C light to indicate whether the points are free to swing or locked by a route (or flank) rather than using the centre indication for this.

Perth for one, off the top of my head. Though I am sure I have also seen it elsewhere.

I had a look around for pictures of the older panel and that doesn't appear to have been any different: https://www.flickr.com/photos/llangollen_signalman/5830019728/ Quite an unusual installation, though, Perth. Very nice, mind Last edited: 15/11/2020 at 14:45 by TUT Reason: None given Log in to reply |
