Rail types

Railtype variables

Railtype properties

Sort order

The sort_order influences the sort order of the drop down lists with rail types. Default values are as follows:

Base speeds for curves

The base speeds relevant for the curve_speed_multiplier are:

Graphics blocks for railtypes

Rail types define a number of fixed graphic blocks:

The entries marked by * are required. A typical implementation for railtypes can look like

item(FEAT_RAILTYPES, elrail, 0x01) {
    property {
        label:                      "SHIN";
