'Neck' is probably to describe its location rather than function, ie it's at the station neck. Just a variation on Up siding, or down sidings, could equally well have been centre siding, but that's what they called it I guess some 160 years ago so we can't check with the station developer.

Neck siding, headshunt, station throat - the theme seems quite obvious...

Clive, Just goes to show that what one sometimes takes for granted is quite different from what's expected. <Getting of the floor after falling out of my chair while reading> Excellent stuff Thanks, NR Log in to reply |

Let me add my thanks to Clive's post too. Makes SimSig a whole lot more understandable.

My favourite single tale is the time that four trains all left from the same station at the same time, all along single lines, all with the wrong token! What's more, in two cases the line used Tyers Number 3s, which don't allow the token to be replaced in the machine at the originating station.

To which I'd add one Clive has become very familiar with (if not by name); the siding behind signal 48 (bottom of the screen, opposite the ends of platforms 4/5) was "the back of the box". And indeed the base of the 1952 box is still there to this day, on the opposite side to the box Clive has simulated... Log in to reply |

" said:" said:Then there was Port Arthur, and wasn't there another name used at Euston? Don't go confusing us Clive! (I do know where Port Arthur is by the way, a friend of mine (Graham F) was a signalman at Euston in the '80s.) Is the other name you're alluding to The Rat Hole? All goes to show the locals create their own names for things, often a lot briefer then the official name (or perhaps easier understood in a noisy environment). Incidentally, some of these names have historical resonances (like Port Arthur - and I believe there were a number of places that had Klondikes, either yards or sidings), which may offer clues as to the development of a location.

Just a quick one. I can see that wide-to-gauge points are usually found protecting sidings, but in which direction do they work? Do they protect trains on a main line from running into sidings at high speed, do they protect a train within a siding from straying onto the main line, or both? I can't find a definitive answer. In the case of a single catch point, such as at Royston, its purpose seems to be to prevent trains moving (rolling?) Down (left to right) into the station (against the direction of signalling, which is Up), so maybe if one considers a w-t-g point as being equivalent to a pair of catch points, maybe they stop trains on the "stem" of the Y moving "upward" - which translates as moving out of the siding onto the main line.

theyre purpose is as per trap/catch points, prevent an authorised movement from a siding, essentially one on each rail, rather than on a single rail. they open inwards (the ones at sheffield do anyway) so that a train finds a distinct lack of rail to run on and finds itself in the 4' "We don't stop camborne wednesdays" Log in to reply The following user said thank you: maxand |

So another way of putting it is that when they open inward, the wheel flanges of an approaching train soon find themselves on the outside of the w-t-g points and ride up? Thanks for answering the important question, which is that they are intended to act to stop trains moving out of a siding unless signalled to do so.

I worked at Lime St for a year or so from 1989, although not in the 'box. I was told that the purpose of these points was to derail anything running away out of the neck but (hopefully!) without any vehicle so derailed ending up leaning to one side - for obvious reasons. I was also told that should the track circuit that covers the points occupy without a route being called, all the surrounding track circuits would 'flood' and therefore return signals to danger.
