curved top of the loading gauge Explanation: http://myweb.tiscali.co.uk/gansg/2-track/02track3.htm Containers are a good example of how the loading gauge can affect traffic. The original specification for the modern rectangular metal container came from the US defence department and specified a box eight feet high by eight feet wide. As the floor of a standard wagon is about four feet up the upper corners of the container were wider than the curved top of the loading gauge allowed. I think there s no specific term. A "corne" is for example the term used for pantograph horn, in other words, the ends of the pantograph that are rounded or curved downwards to match the shape of the wagon or coach roofs and not foul the gauge |

horn(s) of the clearance profile/envelope Explanation: Are we talking pendular/tilting trains by any chance? Whether tilting or not, I imagine the phenomenon is the same, however. The gabarit is the profile/envelope occupied by a train (or other vehicle). There are various types. The "clearance profile" or "clearance envelope" - sometimes preceded by "kinetic" - is the space within which a train can be expected to move: it can rock and roll sideways as it travels, or move up and down on its suspension, and its ends will move outwards on corners. If you draw all these shapes overlapping each other, you get a couple of "horns" at the two top corners of your envelope/profile. If by some misfortune two trains passing each other happen to "rock and roll" in such a manner that their respective "horns" overlap, they will touch and damage each other. I don't know that this expression is said, so only low confidence, but the image is a good one. -------------------------------------------------- Note added at 11 hrs (2010-08-23 08:10:40 GMT) -------------------------------------------------- Thinking about it, I've come to the same conclusion as Polyglot and Clanola. My "horns" are eliminated by rounding the top corners of wagons or containers. Au premier abord, la définition du GABARIT LIMITE D’OBSTACLE telle qu’elle ressort de l’enquête paraît globalement homogène et conforme à la notion explicitée au chapitre 1 ; on notera cependant que la terminologie employée n’est pratiquement jamais la même (voir encadré ci-dessous). [...] le GLO est déterminé à partir du gabarit dynamique enveloppe des véhicules auquel est ajouté une lame d’air de 15 cm ainsi que des CORNES et VENTRES dans les courbes; [ ... ] Ainsi, certains professionnels considèrent que les éléments suivants sont bien pris en compte dans le gabarit dynamique : les CORNES ET VENTRES dans les courbes http://www.coliac.cnt.fr/UserFiles/File/GLO rapport.pdf Tout cela montre la complexité du problème du gabarit devant le nombre de paramètres entrant en jeu. Actuellement s'ajoute la tendance à l'agrandissement de ce gabarit UIC dans les CORNES de celui-ci (suivant croquis) pour admettre la circulation de chargements plus encombrants (semi-remorques routières, conteneurs, voitures à étages, etc...) Ainsi sont apparus des extensions du gabarit UIC appelées GA, GB, GB, GC qui font l'objet d'études et surtout de réalisation sur certains itinéraires privilégiés mais qu'il sera malheureusement quasiment impossible de généraliser, http://www.mulhouseum.uha.fr/site/_sys_ressources_preview.ph... En principe on peut prendre le déport au ventre d'un véhicule le plus long possible mais celà ne suffit pas. Il se peut que le gabarit soit induit par le véhicule le plus court possible mais ayant le plus grand porte-à-faux, par son déport à la CORNE http://www.lrpresse.com/trains/viewtopic.php?p=904093&sid=c2... But oddly, this proposed gauge has square TOP CORNERS www.rfg.org.uk/files/y70622DDDBaker.p a tunnel at Km 263 between Spezand and Sibi provides clearance of only 29 cm between the inner tunnel wall and the TOP CORNERS of super high cube containers loaded on wagons of 1200 mm height. In this case, the vehicle gauge infringement is 5.1 cm, http://www.unescap.org/ttdw/Publications/TIS_pubs/pub_2182/t... Clearances were tight, as can be seen in the clearance diagram above. The 'TOP CORNERs' gave the closest measurements, tunnel walls being a mere 6 inches (150mm) from the standard loading gauge in use during the 1920's. http://www.rimutaka-incline-railway.org.nz/route/mangaroa-tu... File Format: PDF/Adobe Acrobat by AS Fowkes - 1989 - Cited by 1 - Related articles were parked on the rail track it would infringe all but the UIC gauge at the TOP CORNERS, and this is before it is placed on a rail wagon. ... eprints.whiterose.ac.uk/2271/1/ITS66_WP285_uploadable.pdf The immediate cause of the incident was that the combination of the container and the type of wagon it had been loaded onto was too high for the route on which the train was travelling, and the left-hand TOP CORNER of the container struck the platform canopy. [ ... ] The difference between the two is that the W6a gauge is essentially an arch shaped profile, while the W8 gauge uses the same basic shape with cutouts in the ‘arch’ to accommodate the TOP CORNERS of the container (Figure 8). [ ... ] This requires the capacity of the route to be enhanced to accommodate the W10 gauge, which is 273 mm higher than W8 at the TOP CORNERS (Figure 8). [ ... ] There were no black/yellow markings on the TOP CORNERS of this container to indicate that it was a high-cube, http://www.raib.gov.uk/cms_resources.cfm?file=/090812_R21200... Alstom was asked to develop outline proposals for the trainsets, examining three different vehicle designs (Fig 1). Keeping the essential TGV concept of articulated cars, the train would have steel-bodied trailers to a large-profile design with a well between the bogies able to hold four AMJ containers; these could be 2•5 m high, or 3 m if they have tapered TOP CORNERS, with a maximum load of 4 tonnes each. http://www.railwaygazette.com/news/single-view/view/10/air-f... Height of them fits the loading gauge, only problem might be the TOP CORNERS!!! http://fictitiousliveries.fotopic.net/p28196784.html The issue is the TOP CORNERS of the car being to tall & wide, the tunnels would have to be notched out from round on the top to square http://forum.atlasrr.com/FORUM/topic.asp?TOPIC_ID=50647 "Rounded top corners" maybe? |

Reference: Corne: From Wikipédia Reference information: Ces gabarits ont tous la même largeur, 3 150 mm, ils ne diffèrent que dans les parties hautes, 4,320 m pour les GA et GB, 4,70 m pour le GC. La différence entre les gabarits GA, GB et GB1 se trouve au niveaus de la « CORNE », c'est-à-dire au raccordement de la rive (limite verticale) et du ciel (limite horizontale haute). Elargir cette CORNE permert de passer des conteneurs ou des caisses de camions plus larges ou plus hauts http://fr.wikipedia.org/wiki/Gabarit_ferroviaire But the English version does not seem to discuss the ''corne'' outright. http://en.wikipedia.org/wiki/Loading_gauge |
