Hi all. As a complete TEMPLOT beginner I decided to try it all out by designing (using pug 0.91.c) a simple shunting plank. However, after a couple of false starts, I got carried away and the 'plank' is now 15 feet long and 2 foot 6ins wide! As it's S7 I needed to save space where I could or there would be no space in the house to errect it, so in the middle is this curved double slip which I offer for your comments. I didn't quite follow the sequence in Martin's video as I found it easier (after altering the switch of the turnout based on the curved diamond and saving a copy) to attach the turnout to the peg, MCP or TCP as appropriate, and then manipulating it by swapping/inverting the hand until it obviously lay on the diamond in the right position. Once there making the slip road was easy and guranteed to be right. I say this after making numerous mistakes and getting some very weird slips, incliding those in which the switch blades were outside the point entirely. Anyway, here it is. Phil |

Hi Phil I have had a look at your double slip and I see that your bottom slip road has minimum radius of 43" which scales out at 2.34 chains this will only be suitable for 0-4-0 locos and short wheel base or bogie wagons. Is this what you have in mind for using on your layout? Cheers Phil |

However, designing your slip as an outside slip - with the switch blades outside the diamond - should increase the radius of your slip road and make things a bit easier. I always think that an outside slip is a more attractive formation - notwithstanding the extra crossings required. Jim. |

If you upload the whole .box file rather than just the slip we could perhaps have a look at it. regards, Martin. |

Thanks everyone. Once I've sorted out how to do "quotes" I'll reply to everyone individually. In the meantime, I've spent the day re-visiting the shapest turnouts and curves so ... watch this space! Your assistance is very much appreciated. Phil |

Thanks again folks - I'm attaching the .box files for the St Margarets project (suitably revised in view of your comments) and the revised curved double slip on its own. The original purpose of the project was the production of a rather large 'inglenook' style shunting layout, no passenger trains involved at all. Well, that was the intention, it rather grew as I played with Templot. I'm secretly quite chuffed with it. As you may gather, I don't much like dead straight lines! Phil - Yes, it was intended to be for an 0-6-0 (at most) and vans so I wasn't as concerned as I should have been about curves. Jim - I've only ever seen a rough sketch of an outside slip (there's one on the MRN pages you posted) and have no idea at all how to create the template! All suggestions gratefully received though. Thanks for pointing to my posting on RMWeb Martin. Re-reading it, I rather think my imagination carried me away. I have been doing some rough sketches though and thinking about a mock up using some of that card the re-cycling people won't take away ........ As I said, here they are for your comments and suggestions. Thanks. Phil |

Hi Phil Attached is an outside slip extracted from a plan I did years ago (and can be seen in the flesh* on my website at http://www.paul-boyd.me.uk/ - follow the model rail link then the "EM trackwork" link) Hopefully this will give you a pointer, and I think it should regauge from P4 to S7 fairly well as both are "scale" track standards. * sort of - the photos are of the EM version, the box file is P4 |

Hi Phil Ah yes - the check rail! I've attached a screen shot with the slip road copied to current, and the blanking cancelled. Basically it's a bog standard turnout with the check rail extended ('real'=>'customize V-crossing'=>'wing and check rails...'). Once I have enough check rail, the turnout part is blanked off. There is good help text available on the dialogue box that opens up, but if you're stuck then shout! Incidentally, although my box file is a single outside slip, you can make a double outside slip in the same way. I have no idea if there are any prototype examples of that formation though! |

Paul Boyd wrote: Incidentally, although my box file is a single outside slip, you can make a double outside slip in the same way. I have no idea if there are any prototype examples of that formation though!Hi Paul, Phil, Double outside slips are certainly found in UK track, more commonly in yards than in running lines. Here is a well-known picture of one. Notice that it is not symmetrical, the left-hand slip road is longer and to an easier radius than the right-hand slip road. Which adds to the fun of building it. double_outslip.jpg There is a picture of a double outside slip in a running line on page 43 of "A Pictorial Record of Great Western Signalling" (OPC). That one is also non-symmetrical. As usual, the photographer waited until there was a wheeled object in the way before taking a picture of the track. A special form of double outside slip is much used in Germany, and available in model form from Tillig: AAAA-85391.jpg © http://www.internationalmodels.net That design has a common centre rail or casting. On the UK prototype it is essential that the centre rails are at least 6" apart in the middle, so that if one wears down more than the other, wheels running on one do not hit the side of the other rail. The problem of a wheel running on a worn rail hitting an adjacent rail is quite common in UK prototype track design, and has to be allowed for. Sometimes the ends of wing and check rails have 1/4" machined from the top to allow for wear on a close-by running rail. For example the nearest wing rail end on the left side in the picture in the signalling book might be such a case. Fortunately in models this is not something we have to bother about. (Apart from modelling it of course! 1/4" is 3 thou in 4mm scale, the thickness of thin paper.) regards, Martin. |

Much of it can be seen in "Great Wesern Signalling" by Adrian Vaughan (OPC), Pg. 43. It replaced an even more hairy mixed gauge single slip, see eg "The Great Western at the turn of the Century" by AR Kingdom (OPC) Pg. 9, upper and partially in "Swindon Engineman". by G Shurmer & M Fenton (WSP), Pg 216.

Now I have just got to build one of these. It would be fairly easy to construct - just start with the innermost straight section, as you normally so do in construction of tandems, slips and crossings, and work your way outwards. But with my limited skills with Templot, I would have to just scribe a few lines with a trammel and work from those - unless Martin came up with a tutorial..........

Paul has kindly posted his outside slip which is in P4 - How do I convert it to S7 please? Thanks. Phil PS I've looked at the outside double slip photo, the switches seem to be operating independently. Following the route of the bottom left switch is is set into the road on the right whereas the switch at the other end is set straight. The other slip road is the same. No point levers shown so either they're on a box (although not the on in the background) or a groundframe. Where was the photo taken please? |

Then go to the full gauges list (other gauges... menu item). Select the new gauge/scale standard you want on the list. Then click the convert group button at the top of the dialog. You will be ok converting from P4 to S7, but there are some points to bear in mind for other conversions -- see: topic 368 regards, Martin. |

Following the route of the bottom left switch is is set into the road on the right whereas the switch at the other end is set straight. The other slip road is the same.Hi Phil, The slip is set for the straight road bottom left to top right. When worked from a box, both switches at one end of a double slip work together on one lever. Both switches at the other end work together on another lever. But the two ends are independent. That gives a total of 4 possible lever combinations, corresponding to the 4 possible routes through a slip. Only one route is ever available at any given time. In the picture it is bottom left to top right. In the picture there is the end of a check rail showing bottom right, and this slip is clearly part of a crossover to the running line on the right. The switches at the far end are rodded and interlocked from the box, and the ground signals at that end control access from the sidings to the running line. The lever working the far switches is probably also working the switch for the turnout out of sight in the running line bottom right, the usual arrangement for a crossover. Although in a yard like this the nearer switches are probably worked from independent hand levers (we can't see), in the picture all the switches are actually set exactly as they would be if rodded and interlocked from a signal box. Where was the photo taken please?Sorry, I don't know. Clearly it is pre-grouping. I scanned it from a 1922 book on trackwork design (Hepworth and Lee), but it is quite well-known and I have seen it published elsewhere. I think it is in the Gauge 0 Guild's trackwork manual. Anyone know the location? regards, Martin. |

I wrote:Although in a yard like this the nearer switches are probably worked from independent hand levers (we can't see), in the picture all the switches are actually set exactly as they would be if rodded and interlocked from a signal box.On further thought I think the switch bottom right is also rodded from the box, hence the provision of two separate ground signals according to the setting of this switch. The signal wires will be running through a detector on this switch. If it was hand operated, almost certainly there would be only one ground signal for both roads. Also the hand lever would be on the left, away from the running line, and there is no sign of a suitable linkage. The switch on the bottom left might be a hand lever, or might be rodded from the box. However with the other three switches rodded I think it likely that this one would be too, and the lie of the switches is in accordance with this. double_outslip.jpg regards, Martin. |

Thanks Martin. When you think about it, would any signalling scheme allow ends of the same point to be separately controlled? Both ends are 'on the box' in some fashion, but it is plainly possible to set a route which could result in a run through. Of course we can't see the crossover behind the photographer and presumably the the mechanical locking wouldn't allow the clearing of a signal for a plainly wrong route, but (as I tell trainees) signals do not put an inpenetrable barrier across the railway .....

Evening all. After re reading this thread, as its been a while since its seen any updates. I'm intrigued with the double outside slip. As we've only managed to find references to two such slips, I was wondering whether people thought that I could realistically model one in an urban industrial setting in the Midlands for a 1970/80s themed layout based around a steel terminal? The idea being that with such a slip that it makes access to all four corners of a layout a lot more pleasing on the eye. To be honest I can get away with using a standard double inside slip, but the double outside looks like a real challenge. It's either the slips or a trailing point into a four way turnout ( three to the left one to the right), I can't quite decide on that either though. Dave |

Hi Dave, If you are talking private industrial sidings which had been in place since before say 1970 I think you can easily have such a double outside slip if you want one. It might be original construction from much earlier, or second-hand material re-claimed from elsewhere in the 1950s or 1960s. Tracks in industrial sidings can be very long-lived, and renewals are often second-hand. If you are talking BR-maintained track in the 1970/80s I think it's not impossible, but you would need some evidence of very old track still in use locally to be convincing. If it was really the only way to make the essential connections within the available space then why not? On the other hand BR tended not to build and maintain special one-off formations just for the fun of it because they look interesting! By the 1980s such old trackwork is much more likely to be either long-since out of use and buried in weeds, or to have been rationalised down to something much simpler and easier to maintain. regards, Martin. |
