NUTS uses just a few basic classes of wagons, each of which can load wide variety of cargoes. The technically most important wagon is the Universal Wagon, which is able to load ALL_CLASSES of cargo, except passengers and mail. This means that the train set as a whole works with any possible industry set. Even if it was some unknown cargo which is not defined by the correct cargo type label, it would work but it would show all hopper cargoes as coal, flatbeds as goods, and tankers as oil.
Currently recognized cargo labels are all cargoes from original industries, FIRS, Pikka's Basic Industries, ECS and Martian Industries.

Recognizing wagons

NUTS follows a logic that every wagon should be easily identifiable which cargo is carried by it. Not only when the wagon is full, but also when it is empty.
  • First of all, all cargoes are visible on/in all wagons. That applies not just for flatbed of hopper cargoes, but also for tankers so you could see if the train is empty or not.
  • Secondly, every wagon has a different colour based on the cargo it can carry. Those colours are carefully picked so that in no currently known configuration of industries you can get two wagons of the same type and colour, but different cargo type.

Wagon Types

Flatbed wagons

Generally the wagons on which are cargoes transported in pieces, mainly like crates of goods or food. But also steel, wood, livestock, fruit or even diamonds and gold.
Engineering supplies are transported by flatbed wagons.

Hopper wagons

Any bulk cargo which is mined or farmed is loaded on the hopper wagons. While there is not much to add to this, it is important to note that farm supplies are loaded in hoppers.

Tanker wagons

Any liquids go to tankers, first comes to mind oil or water. Other interesting cargoes are livestock (fish) or fizzy drinks (beer), which can also be transported by flatbeds.

Universal wagons

The ultimate wagons which are able to carry any cargo except passengers and mail. They usually just have the same sprites as other cargo wagons, but always only one of them in case there is a choice available.
Specifically:
Livestock - flatbed form
Fizzy drinks - flatbed form

Express wagons

It is important to note that express wagons change their capacities and loading speed based on the engine they are hauled to, while they also change their appearance to fit the leading trains.

Colour refit

Express wagons also have cargo sub-classes which represent 18 various colour configurations. Express wagons hauled to recolourable engines can recolour via refit. Customize your city network! :)

Wagon classes

Rail wagons

As rail wagons are the ones used in the early parts of the game, they also have generations.

  • 1920: First generation of rail wagons has capacity of 12 x 2 = 24 with loading speed of 2 x 2, resulting in 6 loading stages.
  • 1955: Second generation rail wagons can load 30 units of cargo with loading speed of 6, resulting in 5 loading stages.
  • 1990: Because rail vehicles are slowest, they get highest 3rd gen wagon capacity of 35, loading 7 units per tick - resulting in 5 loading stages.

Rail express wagons hauled by cargo engines have capacity of 60 with loading speed of 12.

Monorail wagons

Coming in 1990 with monorail engines, monorail wagons are something like a middle way with capacity of 30, loading 6 units per tick - resulting in 5 loading stages.

Monorail express wagons hauled by cargo engines have capacity of 50 with loading speed of 10.

Maglev wagons

Maglev not only has the fastest trains but it also has other utility advantages. As a result maglev wagons have capacity of 11 per wagon half, meaning 22 in total. Loading speed is 4, resulting in 3 loading stages.
Maglev wagons attached to SLUGs have capacity of 12 x 2 = 24 with the same loading speed. Introduced with maglev engines in 2000.

Maglev express wagons hauled by cargo engines have capacity of 2 x 39 = 78 with loading speed of 2 x 13.

Chami Wagons

Since 1960, Chameleon (Chami) wagons have a tiny bit lower capacity than future normal monorail wagons or 2nd gen rail wagons - 2 x 14 = 28. Additionally, they also load just 2 units of cargo per tick, resulting in 7 loading stages.

Chami express wagons engines have capacity of 2 x 56 = 112 with loading speed of 8.
