Signs on the railway inform drivers, guards, dispatchers, drivers, and even passengers about what is up ahead, where a place is or what they should do. Below is a list of signs.
Speed Limit Indicators
Speed Limit Indicators informs drivers about upcoming speed limits. The current speed limit is repeated in the driving UI below the current movement speed.
| Type | Explanation | Image |
|---|---|---|
| Permanent Speed Restriction Sign | A white circular sign with a red outline means that the speed limit stated applies to trains after passing the sign. A sign with one or more arrows above a general speed indicator sign indicates that the limit only applies for trains branching off the next point in the stated direction(s). | 
|
| Advance Warning Indicator | A white triangular-shaped sign with a yellow outline informs drivers about an upcoming speed limit which is lower than the currently enforced one. The sign gives drivers enough time to reduce their train's speed to the new limit after passing this sign. | 
|
| "SLOW" sign | A sign with the words SLOW means that drivers should slow down as soon as possible. | N/A |

Whistle Board
The Whistle Board tells train drivers to whistle. It is often placed near level crossings to inform cars, pedestrians and signallers about approaching trains. The sign can be triangular or circular.
When a whistle board is placed next to a signal, like in the third image below, drivers shouldn't whistle until the signal has been cleared.

SPAD Trap Indicator
A SPAD Trap Indicator board is used to warn drivers about an upcoming SPAD trap. SPAD traps (also called catch/trap points) are used to forcefully protect main lines from trains on sidings that are passing signals at danger.
Although there are currently five SPAD traps present in the game (Three at Masonfield and two at the Benyhone Loop), none of them are preceded by SPAD Trap Indicators, meaning that these signs are currently not present in the game.

Level Crossing Ahead Sign
This sign informs drivers of an upcoming level crossing ahead. It can be identified by the black cross on a white background.
While Satus Level Crossing and Dovedale East Crossing have these signs, Marigot Crossing and Narmouth Crossing are not.

Limit of Shunt Indicator
A Limit of Shunt Indicator marks the limit that carriages and locomotives are allowed to be shunted. It appears mostly as a white sign with a red label saying 'Limit of Shunt' or 'Shunt Limit'.

Stopping Marker
A stopping marker tells train drivers where to stop at a platform.
| Type | Explanation | Image |
|---|---|---|
| "S" Car Stop Marker | Found at most of the stations in the game, drivers should stop at those stop markers if there is not a specific one for their train type. | 
|
| Class specific stopping marker | Special stopping markers for some trains like the Class 43 (HST) and the Class 323 can be found at some stations. These are colored differently and show the train type on the marker. |
|
| Old "S" Car Stop Marker | This version of the "S" Car Stop Marker was used on older stations. | 
|
Stop Indicator
Stop indicators is to tell drivers to immediately stop the train before reaching the sign. They are used to warn drivers about the track ending, like at buffers.

Distant Board
Found only on the Dovedale Central turn and between Marigot Crossing and Pallion Harbour, these signs tell drivers to be cautious of the signal ahead as the next signal is around a blind corner and might be in their blind spot if they go too fast. This is a permanent signal and can't be changed.

Platform Sign
This tells passengers, dispatchers, guards and drivers what platform they are standing on.

Countdown Markers
A Countdown Marker tells drivers that a station or a signal is ahead. They are often placed subsequently to inform drivers about the distance.

A sign denoting that a station is ahead.
Poor Adhesion Site
This sign indicates to drivers that due to various factors, there is less 'grip' (adhesion) on the train to the tracks, and they need to be careful. Low adhesion arises from a number of causes, most notably from leaf contamination arising from lineside vegetation. [1] At the end of the site, there is a sign to indicate that the track is back to normal.

AWS Gap
The "Commencement of AWS Gap" sign indicates to drivers that AWS is not available on the following line segment, while the "Termination of AWS Gap" sign indicates that AWS is available again on the following line segment.[2]
These signs are currently only installed at the beginning of the line branching off at the Satus Services sidings.
Low clearance indicator
When you see this red and white chequered sign, this is to inform potential engineering teams that the next section has limited clearance and they will need to take extra measures to make sure they're not involved with an accident with a train. This can be found at places like between Pallion Harbour and Dovedale Central or Perthtyne where either width clearance or height clearance is low.
