Railway system comprising: i) a railway sleeper having a predominant longitudinal extension in turn comprising: - a first and a second fixing zone (21, 22) of corresponding lengths of rail; - a first channel which extends along the longitudinal extension; said first channel dividing at least the first fixing zone from the second fixing zone; said first channel being suitable for passage of cables; - a third and a fourth fixing zone (23, 24) of corresponding lengths of rail;the first and the third fixing zone (21, 23) being located in succession along the longitudinal extension of the sleeper;the second and the fourth fixing zone (22, 24) being located in succession along the longitudinal extension of the sleeper; ii) a first rail comprising a first and a second length (111, 112) consecutive to one another along a preponderant direction of extension of the first rail; iii) first connecting means of the first length to the sleeper, said first connecting means being constrained to the sleeper in said first fixing zone; iv) second connecting means of the second length to the sleeper, said second connecting means being constrained to the sleeper in said second fixing zone; v) a first electrically insulating joint interposed between the first and second length (111, 112), said first joint being located above the sleeper; vi) a second rail comprising a third and a fourth length (121, 122) consecutive to one another; the first and the third length (111, 121) defining a first portion of a railway track; the second and the fourth length (112, 122) defining, in combination, a second portion of the railway track; characterized in that the system further comprises determination means for determining the passage of a train along the first and/or the second portion (101, 102) of the railway track, said determination means of the passage comprising a plurality of cables running in the first channel and which are electrically connected partly to the first length, partly to the second length, partly to the third length, and partly to the fourth length.. i) a railway sleeper having a predominant longitudinal extension in turn comprising: - a first and a second fixing zone (21, 22) of corresponding lengths of rail; - a first channel which extends along the longitudinal extension; said first channel dividing at least the first fixing zone from the second fixing zone; said first channel being suitable for passage of cables; - a third and a fourth fixing zone (23, 24) of corresponding lengths of rail;the first and the third fixing zone (21, 23) being located in succession along the longitudinal extension of the sleeper;the second and the fourth fixing zone (22, 24) being located in succession along the longitudinal extension of the sleeper; - a first and a second fixing zone (21, 22) of corresponding lengths of rail; - a first channel which extends along the longitudinal extension; said first channel dividing at least the first fixing zone from the second fixing zone; said first channel being suitable for passage of cables; - a third and a fourth fixing zone (23, 24) of corresponding lengths of rail;the first and the third fixing zone (21, 23) being located in succession along the longitudinal extension of the sleeper;the second and the fourth fixing zone (22, 24) being located in succession along the longitudinal extension of the sleeper; ii) a first rail comprising a first and a second length (111, 112) consecutive to one another along a preponderant direction of extension of the first rail; iii) first connecting means of the first length to the sleeper, said first connecting means being constrained to the sleeper in said first fixing zone; iv) second connecting means of the second length to the sleeper, said second connecting means being constrained to the sleeper in said second fixing zone; v) a first electrically insulating joint interposed between the first and second length (111, 112), said first joint being located above the sleeper; vi) a second rail comprising a third and a fourth length (121, 122) consecutive to one another; the first and the third length (111, 121) defining a first portion of a railway track; the second and the fourth length (112, 122) defining, in combination, a second portion of the railway track; characterized in that the system further comprises determination means for determining the passage of a train along the first and/or the second portion (101, 102) of the railway track, said determination means of the passage comprising a plurality of cables running in the first channel and which are electrically connected partly to the first length, partly to the second length, partly to the third length, and partly to the fourth length..
