Skinnerne var våde efter regnen, så toget kørte langsommere end normalt.

Because -ne is the definite plural ending in Danish.

Here is the pattern:

• en skinne = a rail
• skinnen = the rail
• skinner = rails
• skinnerne = the rails

So skinnerne means the rails.

Most literally, skinnerne means the rails. It refers to the metal rails themselves.

A related word is sporene, which is closer to the tracks as a whole. In everyday translation, English might sometimes say the tracks were wet, but the Danish sentence specifically uses skinnerne.

Because våde agrees with the plural subject skinnerne.

With predicate adjectives after være (to be), Danish usually shows number agreement:

• Skinnen var våd = The rail was wet
• Skinnerne var våde = The rails were wet

Notice that var stays the same, but the adjective changes:

• singular: våd
• plural: våde

In Danish, the past tense of være (to be) is var for both singular and plural.

So you get:

• Skinnen var våd = The rail was wet
• Skinnerne var våde = The rails were wet

Unlike English, Danish does not switch between was and were here.

Regnen is the definite form, meaning the rain. In this sentence, it refers to a specific rain event, so efter regnen means after the rain.

You can also say efter regn, but that sounds more general, like after rain or after rainy weather.

So the difference is roughly:

• efter regnen = after the specific rain
• efter regn = after rain in general

Here så means so. It connects the two parts of the sentence and shows a result:

• Skinnerne var våde efter regnen = first situation
• så toget kørte langsommere end normalt = result/consequence

So så is functioning as a coordinating conjunction meaning so.

Both patterns are possible, but they mean slightly different things in terms of emphasis.

In the sentence you have:

• så toget kørte langsommere ...

Here the subject toget comes first in the second main clause, so the order is the normal main-clause order:

• subject + verb = toget kørte

You could also say:

• så kørte toget langsommere ...

That version puts kørte before toget because så is followed by another element in first position, triggering normal Danish main-clause inversion. In practice, both are understandable, but så toget kørte ... is very natural when så works like so introducing the result clause.

Kørte is the past tense of køre, which means to drive, to run, or to travel depending on context.

With trains, køre is the normal verb:

• Toget kører = The train is running / goes
• Toget kørte = The train was running / went

The whole sentence is in the past, so Danish uses kørte.

Because the sentence is making a comparison: slower than normal.

• langsomt = slowly
• langsommere = more slowly / slower

In Danish, the comparative form langsommere is used both as an adjective and as an adverb in many cases.

So:

• Toget kørte langsomt = The train moved slowly
• Toget kørte langsommere = The train moved more slowly

End means than in comparisons.

So:

• langsommere end normalt = slower than normal / slower than usual

Here normalt means something like normally or as is normal. This is a very common Danish way to express comparison with the usual situation.

You can think of it as an idiomatic expression:

• end normalt = than usual / than normal

Because toget is the definite form: the train.

Danish often adds the definite article as an ending:

• et tog = a train
• toget = the train

The sentence is talking about a specific train, not just any train, so toget is the natural form.

Yes. It is a very normal structure:

• cause: Skinnerne var våde efter regnen
• result: så toget kørte langsommere end normalt

Danish often links cause/result ideas this way with så. It is straightforward and natural in both speech and writing.
