Car Structure Overview

Resource Mass

Any resource in a ResourceContainerProxy component contributes to a car's total mass. The density of each resource is as follows:

Fuel Sand Oil Water Coal Electric Charge
0.85 1.0 0.9 1.0 1.0 0

Anything else defaults to a value of one (1.0).

Total mass is the amount in the container multiplied by the density.

Damage Properties

The damage property values of base game rolling stock. All liveries are the same for each type unless stated. If something isn't here, it follows the defaults at the bottom of the table.

HP and Prices

The prices and HP of the base game rolling stock. Only locomotives have HP values and prices. Body HP is in the previous section, as it is part of a different structure.

Battery Voltage

You can find the minimum and maximum voltages used in DV based on the battery chemistry used:

Chemistry Min Voltage Max Voltage
Lead Acid Cells * 1.94 Cells * 2.15

Gauges

Track Gauge

Derail Valley tracks use standard gauge (1435mm). You can use mods to change it, but you'll still need to make your car's wheels match standard to work properly.

Loading Gauge

Depending where you are on the map, the amount of space you have for a wagon changes, however there are still good limits to follow if you wish your custom cars to be compatible with most of the map. Below is a diagram with safe measurements.

Loading gauge

A car that is at most 3.7m wide and 5m tall will fit everywhere in the valley (except Sawmill, which has a height limit of 4.5m on one of its yards but that will be raised in the future).

Catenary will be at a height of 6m, so you should still strive to be below that value.

Tunnels have a height at the centre of 7m, however they are oval in shape. You should completely avoid the red area.

For width, 3.7m covers most track, including entering service sheds.

Tip

Most vanilla rolling stock has a max height of 4m and max width of 3.2m.

Warning

Custom car overhang can reduce the maximum width allowed in curves. This overhang increases the longer your custom car is.

Icon

The car's icon must follow some specific sizes to fit. Below is a template with the correct dimensions, with wheels in place to match the standard length of a car.

Here's a palette of all colours used by DV.

For Paint.NET users, you can import this file as a palette: dv-vehicles.txt

TextMeshPro

If you need to use TMP, you MUST use the same version Derail Valley uses: 2.2.0-preview3.
