of course the signals create blocks! it is important to note here that a lot of the discussion about signals has been greatly influenced by openttd nomenclature, where different types of non prototypical signals are distinguished by confusing semi-prototypical names. a block in openttd is not the same as a block in real railway terms.

in real railway terms the track is pretty much always divided into blocks and if in train fever you add multiple signals to a track section in succession then you will have subdivided the sections into smaller blocks.

besides that, of course it does not help the discussion at all that around the world there is a vast number of different signalling systems which are different mostly only in the details but often use different names for the description of very similar funtions.

in germany we distinguish between on the one hand block signals, which are placed on sections of open track (between stations) to guard simple blocks or junctions and on the other hand entry-, intermediate- and exit-signals, which are placed within stations. however, this distinction in naming is only made because within stations these signals may under some circumstances demand a different behavior from the driver. in fact the station is just as well divided into blocks, so called “stationblocks”, and the signals function in exactly the same way as those out on the open track.

the principle is always the same, for an (absolute) signal to be set to an aspect that allows the train to proceed, the following block needs to be clear and the switches (if there are any) need to be set correctly.
