Until 1938, the railways of Austria employed left-hand running, but the annexation by Germany led to an enourmous expenditure being made on altering operations to right-hand running and the deployment of german-stle signals. Previously, signal arms pointed to the left side, and they had no circles on their ends. The arms were of a very strange 'louvred' pattern having rows of vertical slits in them to diminish wind pressure and risk of ice accumulating. They were however painted white with red borders, like the German ones. The posts of these signals were tubular steel. The signals had the 'two arms for junction signals' arrangement like the German ones, only the arms were much closer together, so that the lower one extended over the fulcrum of the upper when in the vertical position. The Austrian distant signal was basically like the German one, except that the board was an orange rectangle instead of a disc, and it too had the 'louvre' pattern.
Austrian semaphore signalling was also used by railways in countries once associated with Austria -the Czech Republic, Slovakia, Hungary, Slovenia and other parts of former Yugoslavia. Some of this may still be in use.
The control of movements at any station was in the charge of the Station Director or Station Master, and in typical circumstance there would be a box at either end of the station controllling the points and signals. The Station Director would instruct the signalmen which moves were required through Rank block instruments.
Signals also followed the style of German signalling, with the ubiquitous "blob" on the end of signal arms, and striped posts. The provision of running signals appears to have been kept simple, but every set of points (whether worked from the box or hand-operated) would be provided with an indicator disc to show which way they were set.
Modern OBB signalling has transformed the position. The colour-light
signalling of today employs multiple-aspect signalling with a large range of
indications for the speed signalling system.
