摘要： PROBLEM TO BE SOLVED: To provide a rail correction device and a railroad coach capable of increasing adhesive coefficient between a wheel of a traveling train and a rail and, at the same time, removing metal fatigue layer, corrugated abrasion layer, rust or the like of the rail.
SOLUTION: The correction device mounting auxiliary wheels 12 and 13 having different diameters from each other for correcting the rail on an axle 14 separately from a main wheel is provided to the body. When the auxiliary wheels 12 and 13 are rolled on the rail, both of them are rotated in a state to make occurrence of slippage by the diameter difference. In other word, when either one of the auxiliary wheels 12 and 13 rolls the rail 11, there is a slippage in the other one of the auxiliary wheels 12 and 13. Accordingly, the auxiliary wheels 12 and 13 are rotated in a state to make occurrence of slippage, the correction of the rail is made by taking advantage of the slippage, and the rail can be more effectively corrected in comparison with such a case that the correction is carried out by regular rolling contact.

摘要： PROBLEM TO BE SOLVED: To generate adhesion necessary between a wheel of a traveling rolling stock and a rail by switching a traveling course of a rolling stock from a first track to a second track by means of a course switching device for giving surface roughness to the tread face of a wheel in a wheel machining part. SOLUTION: A determination unit 12 computes a surface condition of a wheel in a railway rolling stock traveling on a traveling rail 1 on the basis of a detection result given from a first detection unit 10 and a second detection unit 11 so as to determine whether adhesion necessary between the wheel and the rail can be secured or not under the present wheel surface condition as against a weather condition. If it is determined that necessary adhesion cannot be secured, a lead rail 14 is moved so as to guide the railway rolling stock to a second track (wheel machining rail 2), while the railway rolling stock is guided to a first track (traveling rail 1) if it is determined that necessary adhesion can be secured. The railway rolling stock guided to the second track travels on the second track at a low speed. Consequently, an uneven shape of the first rough face in the wheel machining rail 2 is transferred to the tread face of the wheel and surface roughness is provided on the tread face of the wheel.

摘要： PROBLEM TO BE SOLVED: To provide an instrument and a method for measurement which can accurately measure the temperature of a rotary body by using a thermocouple fitted to the rotary body across a slip ring. SOLUTION: This rotary body temperature measuring instrument has the thermocouple 10 fitted to the rotary body 31, the slip ring 43 which has terminals provided on a rotation side and a nonrotation side, and a couple of conductors 11 which are connected to the nonrotation side terminal 44b, and measures the temperature TA of the rotary body (measurement point A) through the slip ring 43. Further, the instrument has a temperature IC 12 which measures the temperature TC of the rotation-side terminal 44a (contact C) and a thermocouple 14 which measures the temperature TD of the nonrotation side terminal 44b (contact D). The difference (TC-TD) between the temperature TC and temperature TD is used as a reference value to derive the influence of an external factor on the rotation-side terminal and the correlation with the temperature TA is found to measure the accurate rotary body temperature TA.
