This report gives an account of the results of the tests to which 14 railway coaches were submitted in the Vienna Arsenal testing station in 1964. The tests were conducted according to the principle laid down by Specialists Committee B 30 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 Chapter 10 of this report. Rolling stock of the following types were tested: Open central-gangway saloon and compartment coaches, couchette coaches, sleeping cars, diesel railcars, driving trailer coaches, air-conditioned coaches of a luxury train and dining cars. Although the heating systems and air-conditioning systems differed appreciably, attempts were made to carry out comparable tests on all vehicles. Generally, tests were first carried out 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, the distribution of the temperatures, 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 of freezing and excessive heating 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 carried out to assess the insulation of coach bodies. 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 the proportion of intentional ventilation. Various special tests were carried out at the request of some Administrations, such as measurements of the air quantities, the noise and the distribution of static pressure inside the vehicles, tests for ascertaining the rise in temperature of the main power cable at high loads and various outside temperatures, pre-heating and regulating tests at rather low or high voltages and at very low steam pressures. The most significant results are tabulated numerically and also shown diagrammatically. Extreme values of specific tests conducted in 1961, 1962 and 1963 have, if necessary, been plotted to facilitate comparison. Interpretations of the results obtained, in addition to remarks on the special tests carried out, conclude the report.
