<p>
Road stop IDs are NewGRF-local and can therefore freely be chosen in the 0..255 range. A road stop is allocated by setting the 'class'-property, which should therefore be set first.
A road stop is allocated by setting the 'class'-property, which should therefore be set first.<br />
Road stop IDs are NewGRF-local and can be freely chosen in the 0..63999 range, as of version 7 of the <span class="code">road_stops</span> feature.<br />
When loaded into a version of OpenTTD with versions 1 to 6 of the <span class="code">road_stops</span> feature, IDs are limited to the range: 0..254.
Any road stops with IDs outside this range will be skipped.
