Electrical wiring installed in parallel with the locomotive, does not affect the normal operation of the locomotives, which can effectively prevent the transformation of 55 locomotives reconnection due to shifting of the valve caused by inadequate braking system, ease of sync fault, really play the role of the Security Monitoring . This means in 2000 passed the technical identification of Shijiazhuang Railway Branch organization.

This device is a condition of features for DB shunting locomotives, used to prevent oil dilution. Unilateral control by the oil and improve the combustion state of the diesel engine, so there is a certain role in fuel savings. It works by controlling the engine speed control switches unilateral oil DYK. The device in 1999 passed the technical identification of Shijiazhuang Railway Branch organization, and one of the Beijing Railway Bureau 200 years relying on science and technology and the promotion of energy saving and technological achievements and was given six.

The current rail displacement observation method, since the observation post for various reasons easy to move and affect observation, making observation data accuracy greatly reduced, resulting in unnecessary stress relief or adjustment, can not meet the needs of modern management. Observations with this instrument, the fixed observation post on the road shoulder, waist rail Paste Ruler, observation instruments, breaking the traditional methods to improve the observation accuracy, eliminating the need to pull Dazhong repair problems pile buried observation to achieve the observation continuity, to accurately grasp the lock CWR rail temperature, to eliminate blind stress relief, improve the safety factor CWR great significance.

(L) The instrument consists of Hengshui Public Works section and Beijing Topcon Instrument Co., Ltd. jointly developed. It has a novel structure, reasonable structure, small size, light weight, easy to carry, easy to operate, easy to grasp features.

(2) The instrument by Beijing precision instrument testing station testing, the technical indicators in line with national testing standards optical instruments (GB10049-8).

(3) measuring principle. The instrument consists of an optical observation instrument and optics composed of two parts, namely the observer and placed on the shoulder of the road, leveling of the observer in the alignment of the upper end of the tapered tip, followed by observation of each Rail stocks waist ruler and read the value and the last numerical comparison, that come crawling longitudinal rails value.
