Spanish term or phrase:tren auscultador de catenaria
It's the train used to diagnose the condition of the catenary (overhead wires) for electrified train lines. I can't find the specific translation in English.
Explanation: There are several variations on this theme. Here are a couple examples
The Plasser MTW 100 ***Catenary Inspection and Maintenance Car*** is a self-propelled, self-contained vehicle designed for efficient maintenance and inspection of catenary wire.
Guidance of track machines has pioneered the work in this area. Precise location on a good route map accompanies the automatic work of every track or ***catenary inspection and diagnostic vehicle. *** http://www.findarticles.com/p/articles/mi_m0BQQ/is_12_43/ai_...

Catenary
The structure of cables above the track which carries the electric supply for electric locomotives that use overhead electricity collection. The actual cable that carries the current is contact wire. Loosely, the term 'catenary' may also be used for the contact wire itself. Usually the contact wire is suspended from another cable, called the messenger, by means of short vertical supporting cables called hangers. A secondary messenger may also be used in some cases. http://irfca.org/faq/faq-jargon.html
A catenary is a system of overhead wires used to supply electricity to a locomotive, streetcar, or light rail vehicle which is equipped with a pantograph. See also overhead lines
Unlike simple overhead wires, in which the uninsulated wire or cable is attached by clamps to closely spaced crosswires, themselves supported by line poles, catenery system use at least two wires. One wire, called the catenary wire or the messenger wire, is hung at a specific tension value in the shape of a mathematical catenary between line structures. A second wire is held in tension by the messenger wire, to which it is attached at frequent intervals by clamps and connecting wires. The second wire is straight and level, parallel to the rail tracks, suspended over it as the roadway of a suspension bridge is over water. http://en.wikipedia.org/wiki/Catenary_(railways)

Further info. for you: in my rail glossary, I have the following entries:
"ultrasonic testing";;"auscultación por ultrasonidos";
"ultrasonic tester";;"auscultador";

There are quite a few refs. to "ultrasonic inspection" of the catenary, including this one:
NDE of Catenary Wire
Joint research effort between FRA and Amtrak has identified the feasibility of using nondestructive ultrasonic inspection of catenary wire. Future activities will focus on an evaluation of alternatives to ultrasonic inspections and will develop and field test a prototype inspection system for the nondestructive evaluation of catenary wire. This research will be completed in FY 2003. http://www.fra.dot.gov/us/content/928

I've looked into this a bit more, and judging by what I've found, it looks like there are different types of "auscultadores" (including the ultrasonic ones mentioned above).
El auscultador Logytel AC 01 pertenece a la familia de auscultadores que permiten la medida de la geometría de la catenaria. Su función principal es, por tanto, medir la altura y descentramiento del hilo de catenaria con respecto al eje de la vía....El producto permite la medida o identificación de otros parámetros auxiliares físicos y geométricos: la basculación, el aplastamiento, la corrección lateral, la identificación de curvas, la identificación de postes u otros objetos laterales, la identificación del punto kilométrico en el que se encuentra....Para la medida de altura se utilizan sensores de posición potenciométricos. La detección de la posición del hilo, para la medida del descentramiento, se efectúa mediante sensores inductivos de proximidad. http://www.logytel.com/c_auscultador.html
I have found some references to "geometry vehicle" to describe the type described here, although most of the refs. are to TRACK geometry vehicles, some of which also incorporate equipment for the catenary system:
To evaluate the geometry of the contact wire it is necessary to measure the height of the contact wire above the rails and the horizontal position of the contact wire and to know the relative position between track and overhead wire. It is, therefore, practical to have the ***catenary measuring units*** on
the track recording car.
The non-contact laser measuring device, shown in Figure 16.50, is a very compact and precise device which is mounted on the roof of the measuring vehicle and can easily be integrated into a track recording car. In addition, a measuring pantograph for measuring dynamic reaction forces should be available. http://www.esveld.com/MRT_Selection.pdf
The drawing they mention (Figure 6.50) is also interesting.
Given all of the above, unless you know exactly what type of "auscultador" your text is referring to, I'd use the more generic "catenary inspection vehicle/car". Here's a photo and description of a catenary inspection vehicle:
The Catenary Inspection Vehicle was designed and manufactured in Columbia (South Carolina) for TRA which is the National Railway in Taiwan. This machine is the first machine of its kind to be able to measure the location and profile of the overhead catenary wire by non-contact means using lasers and high speed cameras at speeds of up to 100 kph (62 mph). Lasers and high speed cameras are also used measure the track geometry as well. http://www.harscotrack.com/CIV_Taiwan.htm
well this used to be my extra special field and in the UK I can assure you that the catenary wire is part of the OHL structure. Where is your text from?
In the document "catenary" is described as the whole overhead cabling system, so I'm falling more for "catenary inspection"... actually the problematic word is "auscultador", as I couldn't find a specific translation. Also, Wikipedia also mentions "catenary" as the complete overhead cabling group.

please not that in English a "catenary" is part of an overhead line system whereas in Spanish it is the name given to the system as a whole - one of those "false friends"
