Road & Rail Speed Multiplier

Raises the speed limit of the whole road and rail network by x2, x3, x4 or x5. Four resource families carry a speed limit in Transport Fever 3 and all four are scaled: the .street_template.lua resources (town, country and highway streets, tram tracks, the simple/standard/high speed rail tracks, depot and industry tracks), the .bridge.lua resources, the .tunnel.lua resources and the .rcr.lua railroad crossings. The lane speed of the street templates is stored in metres per second, so the base game numbers are exactly the values the build menu shows: 13.89 m/s = 50 km/h for the small town street, 33.33 = 120 km/h for the highway, 27.777 = 100 km/h for the simple track, 44.44 = 160 km/h for the standard track and 97.2 = 350 km/h for the high speed track. Airport runways and taxiways are also street templates but their lanes only serve aircraft, so they are skipped on purpose - a runway is not a road. Pedestrian-only lanes are not a road speed either, which is why a template is only resized when at least one of its lanes carries a car, bus, truck, tram or train. Station tracks and the roundabout / interchange construction scripts write their speed from base game Lua scripts rather than from a data resource, so they keep the values the game designed (a station approach stays at 72 km/h). Vehicle top speeds are untouched as well: this mod raises the limit of the rails, not the rolling stock. Two things are worth knowing before you start: the limit is baked in when a segment is built, so roads and tracks that already exist in a savegame keep their old limit until they are rebuilt or upgraded - the build menu, however, shows the new values immediately. And the scaled values are linear, so x5 turns the 350 km/h high speed track into 1750 km/h, which only pays off for trains that can actually reach it.
