#openttdcoop

You will probably have seen, or participated, in the last Public server game, which was all about logic. I’ll try to explain it in a bit.

After recent interests in self-regulating construction, there was an attempt to improve the usability of such designs. We have already seen self-regulating networks, where dummy trains transfer cargo onto ML trains, and recently self-regulating orders where vehicles could potentially go to all stations. What has not yet been done is to apply a form of regulation to point-to-point passenger games.

Whenever starting a new game, be it local or on #openttdcoop, one important question to be cleared before starting to build the network always is: “What tilelength (TL) are we going to use for our trains?”.
The chosen setting will mostly depend on the size of the map, as you don’t want to have a hundreds train servicing a single coal mine on a 2048*2048 map. However, there is a great difference between using even tilelengths such as 4, 10 or 20 and odd ones like 5 or 11.

The patch setting “When dragging, place signals every: X tiles” should always be set to “2” when playing on #openttdcoop, and most players will also use this setting if playing alone. If dragging signals, you will always have one piece of track with a signal on it followed by one without one and so on.

Now, if trains are jamming up somewhere in the network, for example behind a full station, those trains should block as little space as possible, so that they won’t for example block the mainline.

As you can see in the first screenshot, with signals every 2 tiles, the trains with tilelength 5 (left) fit almost perfectly in between the signals. However, the TL4-trains (right) always have a gap of more than one tile between them and need as much space as the TL5-trains. To fix that, you would have to place additional signals in the gaps, which might look ugly (especiall for straight track, see below) and is a lot of work, as you would have to do it manually.
