Streamlined involves the use of many different signals which the player can choose to follow.
Along Streamlined's tracks stand multiple posts, boards, signs and other builds, which provide information to people on and around the railway. These mostly exist for realism, though a few affect gameplay too.
Signals
Railway semaphore signals (or armseinen in Dutch) are distributed along the rails. As they are mostly for realism, following signals is not required, however it is encouraged with the signal bonus. Signals are shown on the map as a green, yellow or red circle corresponding with their current state. A signal's front is coloured red, the back is coloured with black and white stripes.

In areas with poor visibility, such as sharp corners, signal warning boards are placed alongside the rails to warn players on upcoming signals.
Signal bonus
For following signals, a bonus of up to 25% can be earned. This is discussed more in-depth on the currency page.
The different types of signal

Basic signal
The most common signal in Streamlined. Green means go, red means stop.

Warning signal
The warning signal looks very similar to the basic signal, but has a slightly different shape, lacks the circle at the end and, mostly noticably, has a yellow light in place of the red one. These display the state of the upcoming basic signal: green means the next signal on this track is green. A yellow warning signal means the next basic signal is red, advicing trains to slow down so they can stop in time.
Basic + Warning signal
This combination of the two show whether the next two sections of track are occupied: the basic signal shows the next section, whilst the warning signal shows the state of the next basic signal.
Double basic signal

Signal posts like this are basic signals for two neighbouring tracks. The lower signal is for the track closest to the signals, the higher signal is for the track farther away.

This picture shows the left signal for the left track, but this depends on what side of the track the signals are located.
Signal bridges
Signal bridges are present at most large stations. Similar to a double generic signal, these hold signals for multiple tracks. It is much easier to see which signal belongs to which track, as the signals will be almost directly above the corresponding track.
Any of the signals mentioned above can be placed on a signal bridge and do not always hold a signal for every track they stand over.
Speed signs
All rails in Streamlined have a maximum speed. There's no punishment for not following it as the speed limit in the game for realism. The game currently has two ways to indicate the maximum speed.

Speed signs
The first method to display the current speed is through speed signs. These are square signs placed next to the track with the new speed limit shown on them. The current speed limit is also shown on the speedometer as a red indicator, which is also the second method used to display speed.

Verkenbord
This board can be recognized by a large white rectangle and a black S. The board means "platform incoming at braking distance", but is only used for passenger trains. The sign may not be accurate if you go faster or slower than the indicated speed of the zone.

S-sign
The S-sign (S-bord in Dutch) looks similar to the "verkenbord" but is smaller, has a pointed top and only one pole instead of two. The sign means you should come to a full stop before continuing with a maximum speed of 40 km/h, unless slower speed was indicated earlier.
Besides these signs, the game shows the current maximum speed with a red indicator on the speedometer.
Other signals and signs

Whistle sign
These signs, with an appearance similar to speed limit signs, are in the game for detail and realism purposes. The large 'F' on them stands for Fluit, which is Dutch for 'Whistle'.
Railway crossing signs
These signs, used both with and without barriers, inform people who wish to go from A to B how many tracks are in their way.
-
Crossing sign for single track.
-
Crossing sign for 2+ tracks.

Loading gauge measuring
The loading gauge structure are placed in various shunting yards in Streamlined. These signal how tall and wide engines, wagons and coaches can be to prevent collisions with platforms, infrastructure and other trains. These are purely decorational since everything in Streamlined has been designed with this in mind.
Trivia
- Prior to version 0.5.23, the speed signs showed the maximum speed divided by 10.
- This was based on a system introduced in 1954. Prior to that, the speed signs showed the full speed like currently in-game.
- The verkenbord and S-sign were the first new signs to be added.
- They were added in version 0.5.24.
