This report gives an account of the tests carried out with two temperature regulating devices used by the Western European railways for regulating the temperature of passenger coaches. The object of the tests was: to examine the characteristics of the devices when new, to submit them to an artificial aging similar to a period in service in a coach of two years, and to re-examine the characteristics of the devices after aging. It become apparent that: aging did not exert an influence with an appreciable tendency on the operation of the temperature regulators; the thermal inertia had not changed. It is felt that it is necessary to draw special attention to the aim of the tests which was to ascertain the properties of the regulating devices from the standpoint of the regulating technique and their modification as a function of the time. Since only one specimen of each type could be tested, the tests do not therefore provide any information about the reliability of these regulating devices in service.
