The present report sums up the results of the tests carried out in the Vienna Testing Station in 1963 on 15 passenger coaches belonging to various Administrations. Vehicles of the following types were tested: Open central-gangway saloon and compartment coaches, couchette coaches, diesel rail cars and driving trailer coaches respectively, and also air-conditioned coaches of luxury trains. Although the heating systems differed, it tried to carry out the same tests on all vehicles. The tests covered first the determination of the pre-heating and pre-cooling periods and that of the energy required for these processes at various outside temperatures. Subsequently, the quality of the regulation of the heating or air-conditioning equipment was tested and the energy consumption of the heating or air-conditioning equipment ascertained at various outside temperatures and speeds; comfort tests were also carried out. The latter chiefly covered the temperature distribution and the air circulation velocities in the compartments. Furthermore, cooling tests were made and also tests for ascertaining the resistance of the equipment to overheating and freezing. A series of k value tests were made with the vehicles at different operating conditions and at various wind velocities. These tests were supplemented by air leakage measurements using radio-active isotopes. Finally, special tests were made to meet specific requests of various Administrations; these tests included noise measurements, pre-heating tests both with voltages which were either lower or higher than the nominal voltage and with low steam pressures. The most important results obtained from these series of tests are given in tables and are graphically illustrated. The extreme values of the results of the tests made in 1961 and 1962 are also plotted, for the sake of comparison, in the same figures. Unfortunately, one series of regulating tests in particular could not be carried out under the same conditions as those applied during other tests, since the general programme of tests which was prepared by Committee B 30 was revised during the summer of 1963. Tables and figures precede a summary of the different series of tests and a critical examination of the test results.
