Spanish term or phrase: S. Escapes y cruces
A series of excel entries, so no context at all I'm afraid

The Document is headed

Interfaces Externas
INTERFAZ DE MATERIAL MOVIL CON ELEMENTOS EXTERNOS
Definición de interfaces entre el Material móvil con elementos externos, tanto de línea (incluyendo túnel y estaciones), como en talleres y cocheras.

This entry is in the GENERAL section:

Radio Mínimo Admisible (excepcional en Talleres y Cocheras y normal en línea).
*Curvas en S. Escapes y cruces*
Peralte y tolerancia.

I assume "cruces" is crossings or maybe junctions

reverse curves, crossovers and crossings
Explanation:
1. As patinba and kpdinicola have already indicated, "S." is part of "Curvas en S.", which is fairly self-explanatory and means S-curves or S-bends. Both these terms are valid, but the one that seems to be most commonly used in relation to railways is "reverse curve". It's also known in Spanish as a "contracurva".

"In civil engineering, a reverse curve (or "S" curve) is a section of the horizontal alignment of a highway or railroad route in which a curve to the left or right is followed immediately by a curve in the opposite direction."
http://en.wikipedia.org/wiki/Reverse_curve

Mario León, whose Diccionario del tren is a standby for railway questions, uses "reverse curve":
http://books.google.es/books?hl=es&id=et6IRQ60RO0C&q=curva e...

But as I say, either "S-curve" or "S-bend" would be fine. By the way, we had a question on "S-bend" in relation to roads, which I answered:
http://www.proz.com/kudoz/english_to_spanish/automotive_cars...

________________

2. An "escape" is not a siding. At least, not usually, although kpdinicola's Mexican source seems to be describing a siding. Normally it's what's known as a crossover. Mario León gives "exhaust", but I think that's a mixup; he gives "crossover" for "escape de enlace" and "double crossover" for "escape doble":
http://books.google.es/books?hl=es&id=et6IRQ60RO0C&q=curva e...

" Agujas dobles o escapes
Un escape, o aguja doble, es la unión entre dos vías paralelas."
See accompanying photo. This is a great page, by the way. "Agujas" are points:
http://comofuncionanlostrenes.blogspot.com.es/2014/01/aparat...

Mario León's definition of "escape" confirms this:
"aparato de vía que pone en comunicación las circulaciones de dos vías, generalmente paralelas, mediante dos desvíos con la misma tangente y con sus ramas desviadas en prolongación una de otra".

For desvío ("switch"), see:
http://es.wikipedia.org/wiki/Desvío_(ferrocarril)

In English:

"A crossover is a pair of switches that connects two parallel rail tracks, allowing a train on one track to cross over to the other. "
http://en.wikipedia.org/wiki/Railroad_switch#Crossover

_____________________

3. "cruce" is less clear. It can mean a level crossing, but I don't think it does here. I think it's just a crossing: in other words, a point where one track crosses another. A crossing has a crossing frog, which is a specially shaped piece of rail, but here I think they're talking about the actual crossing of tracks rather than the frog itself:

"The frog, also known as the common crossing (or V-Rail in Australian terminology), refers to the crossing point of two rails."
http://en.wikipedia.org/wiki/Railroad_switch#Frog_.28common_...

I'd put "crossing".

What all three of these things have in common is that they involve curves that diverge from a straight line, which is why the "radio mínimo admisible" is relevant.

Forgot to say: the normal word for siding in Spanish is apartadero. Apparently in Mexico it's called a ladero o escape. If your text is from Mexico this is the translation, but not otherwise.

In Spain an escape is definitely a crossover, not a siding. Here's further confirmation from an ADIF document (see p. 12):

emergency exits and crossings


Explanation:
if S. Escapes is short for Salidas de Escapes related to tunnels and stations, then it would be an Emergency Exit, and cruce is a crossing

this is simply educated guessing

s-bends in sidings and crossing frogs


Explanation:
The frog, also known as the common crossing (or V-Rail in Australian terminology), refers to the crossing point of two rails. This can be assembled out of several appropriately cut and bent pieces of rail or can be a single casting of manganese steel (Wikipedia)

neutral  Charles Davis: It depends which country the text comes from; in Mexico "escape" means a siding, but in Spain it means a crossover. In other countries I'm not sure whether it's used at all.

S-curves, sidings and crossings


Explanation:

This appears to be a railroad document. The "curvas en S." is one phrase, "cruces" is just as you said, and I researched "escapes" and found the following:

A siding, in rail terminology, is a low-speed track section distinct from a running line or through route such as a main line or branch line or spur. It may connect to through track or to other sidings at either end.
