Seat-Based Capacity & Boarding

Two things the base game does not take into account:

• Seats. A vehicle's capacity has little to do with what you see inside it. Most vehicles carry only about half as many passengers as there are seats drawn in their model (buses about 0.7 per seat, ships about 0.35).
• Doors. Every vehicle has one fixed boarding speed. A tram with seven doors boards no faster than one with two.

This mod raises the capacity of passenger vehicles to match the passenger places drawn in their models, and lets vehicles with more doors board faster.

Capacity

The Capacity rule option decides how:

• Proportional (default): every vehicle of a type grows by the same factor, measured on the base game vehicles as "places drawn / capacity": buses x1.6, trams x2.0, aircraft x2.2, ships x3.4, trains x3.5. A vehicle that was smaller stays smaller.
• Mixed: halfway between proportional and seats only. Vehicles with many places drawn get a bit more, but the order rarely changes.
• Seats only: capacity is exactly the number of passenger figures in the model (crew not counted). One seated figure = 1 passenger, one standing figure = 0.5, 1 or 2 passengers (option, default 1). Vehicles with many figures drawn can overtake bigger ones.
• Seats, never below original: like seats only, but no vehicle loses capacity.

In every rule, ships with two decks get their places shared between the decks (not counted twice), only load options that carry passengers are changed (a cargo-only option keeps its capacity), and cargo vehicles are not changed.

Examples (passengers)

• Large paddle steamer: original 50 → proportional 170, mixed 261, seats only 401
• 1930s liner: original 80 → proportional 272, mixed 286, seats only 301
• Small river steamer: original 20 → proportional 68, mixed 88, seats only 113
• Modern 12 m city bus: original 20 → proportional 32, seats only 39

With "Proportional" the liner stays bigger than the paddle steamer, as in the base game. With "Seats only" the paddle steamer becomes bigger, because more figures are drawn on it.

Boarding speed

• The mod counts the doorways of each passenger vehicle: the parts of the model that have a door-opening animation. The two leaves of a double door count as one doorway, and the side with more doorways is used.
• Each doorway is worth a typical boarding speed for the vehicle type, taken from the base game vehicles: 1.5 for buses, trams and trains, 2 for aircraft, 15 for ships.
• The door option mixes this door-based speed with the vehicle's original speed (default 50%). Doors never make boarding slower than 1/4 or faster than 4 times the original.
• Vehicles whose capacity was raised also board faster (default x2), so stops do not get much longer.
• Vehicles without animated doors keep their original speed (only the capacity factor applies). Cargo vehicles are never changed.

Examples (default options)

• A 12 m city bus with 2 double doors: boarding speed 5 → about 3.9 from the doors, x2 for the higher capacity = 7.7
• An articulated bus with 3 double doors: 3 → about 3.7 from the doors, x2 = 7.3
• A long tram with 7 doors: 5 → about 7.2 from the doors, x2 = 14.5

The articulated bus, which used to board slower than the short bus, now boards about as fast while carrying more people, because it has more doors.

Options

• Standing place counts as: 0.5, 1 (default) or 2 passengers.
• Capacity rule: "Proportional" (default), "Mixed", "Seats only" or "Seats, never below original".
• Boarding speed of passenger vehicles: unchanged, x1.5 or x2 (default). Applies to vehicles whose capacity was changed.
• Door effect on boarding speed: off, 25%, 50% (default), 75% or 100%.

Notes

• Not compatible with Passenger Number Modifier. Use only one of them.
• Works with base game vehicles and vehicle mods. No files of other mods are changed.
• Can be added to and removed from an existing save. Values are recalculated every time the game loads.
• The game's log file stdout.txt lists every changed vehicle in lines starting with [seat_capacity].
• This mod changes gameplay, so achievements are disabled in saves that use it.
