The invention relates to a structure () for housing electronic apparatuses () such as boards () and the like, wherein the apparatuses are arranged in a container with a drawer () insertable and extractable with respect to a frame () of the structure (). On the back wall of the drawer () and on the frame () connectors () are provided which are coupled directly and automatically when the drawer is inserted.

Extractable structure for housing electronic components

A railway circuit for detecting the free or occupied state of the same and for sending signalling information along a railway line to a vehicle travelling along said railway line. A signal generator generates a signal with varying current modulated with FSK technique on a basis of a modulation code. The signal is supplied to a coil magnetically coupled with first and second rails that constitute the single railway circuit to induce a variable current modulated by the code on the electric circuit formed by the portions of the first and second rail short-circuited alternatively by the electric joint. The vehicle is provided with a current sensor suitable for detecting the variable current for extraction of the code and sending the signal to the driver. A signal generator generates a signal in compliance with new safety requirements to determine, with the receiver, the free/occupied state of the railway circuit.
