提出了一种用于测量轨道的设备，特别是用于轨道铺设机，具有布置在其间的两个外部，一个前部和一个后部轨道行进测量滑架（15,21）和中间轨道行进测量滑架（22）。 为了有利的测量，提出指向中间测量滑架（22）的至少一个位置编码器（14,20）与每个外测量滑架（15,21）和至少两个光学传感器（ 16，17），特别是照相机，在光轴（34）上布置在中间测量滑架（22）上，使得至少一个光学传感器朝向后测量滑架（15）并且至少一个其它光学传感器 朝向前测量托架（21）。

It is a device for measuring of track, in particular for track machines, proposed with two outer, front and rear, track mobile measuring carriage (15, 21) and an interposed middle track wheeled measuring cart (22). To allow advantageous measurements, it is proposed that the outer measuring carriage (15, 21) is associated with each at least one to the central measuring carriage (22) oriented position encoders (14, 20) and that the central measuring carriage (22) at least two optical sensors, in particular are arranged cameras (16, 17), in such a way on an optical axis (34), that at least one optical sensor to the rear measuring carriage (15) and at least one other optical sensor to the front measuring carriage (21) is directed.
