Configure Patches Window: Vehicles Section

This window of the OpenTTD patches section enables you to set various settings that affect vehicles and their behaviour. The image below shows the default settings in OpenTTD 0.6.0.

Contents

Configure Patches -> Vehices (0.6.0)

Enable realistic acceleration for trains

Feature availability (since 0.3.2 to 0.6.3)

<1.0

1.0-1.2

1.3

1.4

1.5-1.7

Nightly

Enables a more realistic acceleration calculation for trains. With this setting enabled, trains will travel faster up hill, but slower through tight corners. This option has been renamed to Train acceleration model in 0.7.0.

Possible Settings: On or Off
In Openttd.cfg config file: ([patches] realistic_acceleration=<true|false>)

Forbid trains and ships to take 90 deg turns

Feature availability (since 0.4.0)

<1.0

1.0-1.2

1.3

1.4

1.5-1.7

Nightly

Disallows trains from making sharp 90 degree turns. The NPF or YAPF pathfinder needs to be enabled for this option. Note that due to the way the AI constructs rail paths, certain AI routes will become uncompleteable.

Possible Settings: On or Off
In Openttd.cfg config file: ([patches] forbid_90_deg = <true|false>)

Enable building very long trains

Feature availability (since 0.2.0)

<1.0

1.0-1.2

1.3

1.4

1.5-1.7

Nightly

You can build extremely long trains, aka mammoth trains.

Possible Settings: On or Off
In Openttd.cfg config file: ([patches] mammoth_trains = <true|false>)

Allow goto depot orders

Feature availability (since 0.2.0)

<1.0

1.0-1.2

1.3

1.4

1.5-1.7

Nightly

All vehicles can have a depot in their schedule.

Possible Settings: On or Off
In Openttd.cfg config file: ([patches] gotodepot = <true|false>)

Road vehicle queueing (with quantum effects)

In Openttd.cfg config file: ([patches] roadveh_queue = <true|false>)

Pathfinder for trains

Feature availability (since 0.6.0)

<1.0

1.0-1.2

1.3

1.4

1.5-1.7

Nightly

Select the pathfinding algorithm for trains. YAPF is the default and recommended setting, but you can still select the older pathfinders. This option has been renamed from Use YAPF for trains.

Possible Settings: NPF or YAPF (Recommended)
In Openttd.cfg config file: ([patches] pathfinder_for_trains = <0-2>)

Pathfinder for road vehicles

Feature availability (since 0.6.0)

<1.0

1.0-1.2

1.3

1.3

1.4

1.5-1.7

Nightly

Select the pathfinding algorithm for ships. The original is the default and recommended setting, but you can select newer pathfinder. YAPF for ships has the advantage of not having to use buoys for long distances, but has serious performance issues when using a large number of ships (i.e. more than ten). This option has been renamed from Use YAPF for ships.

Possible Settings: Original (Recommended), NPF or YAPF (Not recommended)
