Ce récit autobiographique, moins préoccupé par le présent que par le passé, n’enquête pas sur un objet dissimulé au regard, mais, bien au contraire, on ne peut plus visible, inévitable, aussi incontournable dans les plaines de la Beauce que le nez au milieu de la figure. Les voyageurs de la ligne Paris-Orléans auront peut-être reconnu le rail de l’aérotrain, structure de béton abandonnée sur dix-huit kilomètres de rase campagne. Enquêter sur cette invention futuriste devenue une ruine monumentale des années soixante françaises donne à Philippe Vasset l’heureuse possibilité de raconter comment notre présent se projette depuis le passé et de suivre l’itinéraire d’une vie voyageuse à partir de son point de départ. « Qu’est-ce qui nous lie à un endroit, sinon la fiction qu’on y projette ? »

The monorail that could have united El Paso, Texas, and Juárez, Mexico - Archpaper.com

This article is the second in a series that originally appeared in AN‘s July/August 2018 issue which focuses exclusively on Texas and was guest edited by AGENCY. The rest of the essays will be released in the coming days and examine architecture and practice across the southern border of the United States.

These days the conversation about the United States–Mexico border is dominated by the implications of building a wall between the U.S. and Mexico. But back in the mid-1960s, there were concerted binational efforts to build a monorail to further connect the commercial districts of two cities conceived as part of one binational community. A 1965 document outlining the proposal for a Juárez-El Paso Monorail System invoked the common origins of both cities. The river was referred to as an obstacle to be overcome: “No other metropolitan community of equal size has been so restricted and contained by so relatively a small item as a channelized river.” Recently, the idea for a monorail has surfaced again, but this time riding on top of a 2,000-mile border wall promoted by an American president to further separate the U.S. and Mexico.

How do linear motors work? A simple introduction

Linear motors are electric induction motors that produce motion in a straight line rather than rotational motion. In a traditional electric motor, the rotor (rotating part) spins inside the stator (static part); in a linear motor, the stator is unwrapped and laid out flat and the “rotor” moves past it in a straight line. Linear motors often use superconducting magnets, which are cooled to low temperatures to reduce power consumption.

Transrapid

German engineers first produced a working prototype in 1971 and developed the Transrapid system a year later. Strictly speaking, the Transrapid uses magnetic attraction rather than the magnetic repulsion normally associated with maglev: the copper magnets are fixed to a “skirt” that runs underneath, and is attracted up toward, the steel track. With considerable support from the German government, Transrapid has been progressively refined into a viable train that can reach speeds of up to 433 kph (271 mph). Decades of investment and development finally paid off in 2004, when Transrapid opened the world’s first (and so far only) high-speed system, the Shanghai Maglev Train (SMT), in China. Although it currently operates on only a short section of track (a mere 31km or 19 miles long), there have been several plans to extend it, though they have repeatedly been shelved.
