RMweb Gold Oldddudders Posted August 27, 2012 RMweb Gold Share Posted August 27, 2012 Exhibit A http://www.ebay.co.uk/itm/390453850404?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648. Note that there are stops, so the bridge can only turn through the 20 or so degrees to connect the pairs of tracks - it is not a full turntable. What does it achieve that a diamond crossing would not also enable? Link to post Share on other sites More sharing options...

shortliner Posted August 27, 2012 Share Posted August 27, 2012 Not sure of the length, but it would allow a short 0-6-0 type loco to be switched between two tracks - see Scrapbook http://carendt.us/scrapbook/page45a/index.html 3rd down the page "Rainers Quay" Link to post Share on other sites More sharing options...
Jim49 Posted August 27, 2012 Share Posted August 27, 2012 Haven't a clue what it is but if you cut off the two stops, could it be converted to a proper turntable? Link to post Share on other sites More sharing options...

Note that there are stops, so the bridge can only turn through the 20 or so degrees to connect the pairs of tracks - it is not a full turntable. What does it achieve that a diamond crossing would not also enable? It looks like some species of sector plate. A diamond crossing or double slip would not allow you to drive on and off at the same end on the two different tracks - with this you can - from both directions.

RMweb Premium Ray H Posted August 27, 2012 RMweb Premium Share Posted August 27, 2012 Does it overcome problems associated with switching the wiring of the frogs in a diamond crossing? Link to post Share on other sites More sharing options...
RMweb Gold Enterprisingwestern Posted August 27, 2012 RMweb Gold Share Posted August 27, 2012 It saves at least 2 engine lengths presumably also. Wasn't there a similar arrangement on one of the North Eastern branch termini? Mike. Link to post Share on other sites More sharing options...
eastwestdivide Posted August 27, 2012 Share Posted August 27, 2012 Although it's described as "pont tournant" in the listing, literally "turning bridge", it does seems to be a term also used for "turntable" as well as for a moving bridge (like Selby for example). Prototype example, described as "pont tournant", with a similar arrangement of exits near the bottom of the page here, on the Austrian Ybbstalbahn: http://www.passion-m...talbahn_p4.html Link to post Share on other sites More sharing options...
trisonic Posted August 27, 2012 Share Posted August 27, 2012 Actually the model is more like a quadruple - slip with a pause in the middle! Probably invented by Brian Harrap (but his is more elegant). Best, Pete. Link to post Share on other sites More sharing options...

RMweb Gold Joseph_Pestell Posted August 30, 2012 RMweb Gold Share Posted August 30, 2012 That's not an item (the model I mean) that I have ever seen before and I don't know why a mainstream manufacturer would make it. But it is a great spacesaver. Not completely unlike a sector plate but those are usually pivoted towards one end. Link to post Share on other sites More sharing options...

eastwestdivide Posted August 30, 2012 Share Posted August 30, 2012 ...But that is an ordinary turntable (albeit dual-gauge) not he gizmo that is on EBay Good point - the gizmo can't do a 360 degree turn, while the Ybbstal thing could. I was misled by the same sort of arrangement of exits. Link to post Share on other sites More sharing options...
shortliner Posted August 30, 2012 Share Posted August 30, 2012 A recent, though somewhat pricey, powered variation from Noch - with three track access - expect cries of severe pain from your wallet! The NOCH micro-motion ready-made model Segment Turntable – that had was announced for December 2011 – is available at the hobby shops now. The Segment Turntable allows locomotives to change tracks even in very confined spaces. As these Segment Turntables require little space, they are mainly used at rural stations and at small railway roundhouses. The extremely compact NOCH model offers three sidings on an area of 20 x 16 cm (7.87 x 6.3 in.) and presents the model railway fan some very interesting shunting possibilities. This highly detailed Laser Cut ready made model can be used with all OO / H0 track systems and is suitable for both 3 rail and 2 rail operations. In analogue operation, the rotary motion of the Segment turntable can be actuated with the switch included. Each release starts moving the segment turntable. In digital operation it is possible to approach each single position directly. Alternatively, the pre-installed digital decoder allows operation from a digital controller. The digital decoder is programmable and automatically recognizes the Märklin®/Motorola® - and DCC/NMRA format. Link to post Share on other sites More sharing options...

RMweb Gold Joseph_Pestell Posted August 30, 2012 RMweb Gold Share Posted August 30, 2012 That's a very nice model by Noch. Shall look it up. But it is the classic sector plate arrangement (all the exits one end) rather than Jouef's effort. Seems unlikely that they would just have made it up. Perhaps there is a prototype somewhere in France??? Link to post Share on other sites More sharing options...
RMweb Gold Joseph_Pestell Posted August 30, 2012 RMweb Gold Share Posted August 30, 2012 Over $200 in the US so I guess some way north of £100 in the UK. While searching for it on the OnTracks website, I was distracted by a whole series of figures called "Lovers in Action". The website tells us usefully that they are "packed in a shock proof box". Opaque plastic? Link to post Share on other sites More sharing options...
Oscale Posted August 30, 2012 Share Posted August 30, 2012 Jouef's sector plate makes more sense than Noch's. The weight of the loco would be balanced on the pivot making it much easier to turn. Link to post Share on other sites More sharing options...
