This report gives an account of the results of the tests to which seven railway coaches were submitted in the Vienna Arsenal Testing Station in 1965. The tests were conducted according to the code of practice laid down by the B 30 Specialist Committee of the ORE. Some of the railway coaches were subjected to special tests which differed slightly from those included in the usual programme of measurements. These tests are briefly described in the Appendix to this report. Rolling stock of the following types was tested: Open central-gangway saloon and compartment coaches, diesel railcars, driving trailer coaches, air-conditioned coaches of a luxury train and dining cars. Although the heating systems and air-conditioning systems differed again appreciably, an attempt was made to conduct tests which were comparable on all vehicles. Generally, tests were first made to determine the pre-heating and pre-cooling periods and the energy required for these processes at various outside temperatures. The quality of the regulating devices, temperature distribution, and the energy consumption at various outside temperatures and speeds were subsequently measured. Comfort measurements provided information on the effects of temperature, air velocity and humidity on the passengers. Tests for ascertaining the resistance to freezing were conducted to investigate the strength of the material and the equipment of rolling stock exposed to various climates. Time constants were determined and k values measured during cooling tests to assess the insulation of coach bidies. A special procedure, using a radioactive mixture of gas and air, was employed in some cases to ascertain the lack of tightness of coach bodies due to their construction and also the proportion of intentional ventilation. Various special tests were made at the request of some Administrations, such as measurements of the air quantities, compartment illumination and distribution of static pressure inside the vehicles, pre-heating and regulating tests at rather low or high voltages and at very low steam pressures. The most significant results, together with appropriate remarks, are tabulated numerically and also shown diagrammatically. Extreme values of specific tests conducted during the years 1961 to 1964 have, if necessary, been plotted to facilitate comparison. Interpretations of the results obtained, in addition to remarks on the special tests, conclude the report.
