Signs on the railway inform drivers, guards, dispatchers, 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 inform drivers of upcoming speed limits. The current speed limit is repeated in the driving UI below the current movement speed.
| Type | Explanation | Image |
|---|---|---|
| Permanent Speed Restriction | A white circular sign with a red outline indicates that a driver must proceed at no more than the displayed speed. If the displayed speed limit is lower than the limit currently applying to a train, the limit applies immediately upon the front of the train passing the sign. If the speed limit is higher, it applies only once the full train has passed it. Arrows placed above the speed board indicate that the speed limit only applies to trains branching off at the next point in the shown direction(s). | 
|
| Advance Warning Indicator | A white triangular-shaped sign with a yellow outline informs drivers of an upcoming speed limit lower than the currently enforced speed, ensuring drivers have enough time to reduce their train's speed before passing the limit board. |

Different Permanent Speed Restrictions
Stopping Marker
A stopping marker tells train drivers where to stop at a platform.
| Type | Explanation | Image |
|---|---|---|
| "S" Car Stop Marker | Found at most stations in the game, drivers should stop at these markers if there is no class specific or length specific marker. Some markers may be marked with "T" or "R", standing for Terminating or Reversing. Drivers should stop at these markers if they are terminating at the station, otherwise they should proceed to the normal markers. Orange/Yellow stop markers are temporary markers, used when the normal stop markers are unusable or obstructed. | 
|
| Length and class Specific Stopping Markers | As trains can have a varying amount of carriages and lengths, stopping markers for trains with certain numbers of cars or for a certain train class can be found at some stations. Length specific markers can often be found at stations with longer platforms. If a train has a number of carriages not matching any one marker, the driver should proceed to the next largest length marker, or the stop marker if there is no larger numbered marker. Class specific markers, such as for the Class 43 (HST), are painted a different colour scheme and should be used in preference to any other marker. |

Whistle Board
The Whistle Board tells train drivers to sound their horn when passing the sign. It is often placed near level crossings to inform cars, pedestrians and signallers about approaching trains. The sign can be triangular, circular or in the historical cut-out form.
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.

Advance warning board
This sign informs drivers of a level crossing ahead. It can be identified by the black St. George's cross on a white background.

Buffer Stops
Buffer Stops signal drivers to immediately stop the train before reaching the sign. They are used to warn drivers about the imminent end to the track.

Possession Limit Board
These boards are comprised of an octagonal stop sign with a steady or flashing red light above. They indicate that the track ahead has been possessed for engineering works, and that the driver must stop immediately and must not pass the board. They can be found on unfinished or unused sections of track.

Limit of Shunt Indicator
A Limit of Shunt Indicator marks the limit that vehicles can be shunted on the wrong direction (left) track of a dual line. It appears mostly as a white sign with red text reading 'Limit of Shunt' or 'Shunt Limit'.

Electrification Warnings
This type of sign is located on the boundary of electrified tracks, alerting drivers of electric trains that they must not proceed as the track is no longer electrified past the sign.
If an electric train is routed to a non-electrified track, the driver should stop immediately and contact the signaller. These signs can often be found in signal boxes to remind signallers of non-electrified lines.
Countdown Markers
A Countdown Marker informs drivers that a station or high-risk signal is ahead. They are often placed subsequently to inform drivers of the decreasing distance.
-

Countdown Markers denoting a signal at risk: DE11 in 200 and 100 metres.
Poor Adhesion Site
This sign indicates to drivers that due to various factors, there is less 'grip' (adhesion) between the train and the tracks, so they will need to be careful. Low adhesion arises from a number of causes, most notably from leaf contamination arising from line side vegetation. [1] At the end of the site, there is a sign to indicate that track adhesion has returned to normal levels.

AWS Gap
The "Commencement of AWS Gap" sign indicates to drivers that AWS is not available on the following line segment, whilst the "Termination of AWS Gap" sign indicates that AWS is available again on the following line segment.[2]

Notice Boards
Notice boards inform drivers of general information for which no specific sign exists. They generally comprise of black text on a white, rectangular sign. One such example is signs denoting the start and end of token working, informing a driver that they must obtain or surrender the token before proceeding.
-
A notice board stating that token working has ended.
Platform Sign
This tells passengers, dispatchers, guards and drivers what platform they are standing on.
-

Low clearance indicator
This sign informs trackside personnel that the following section of track has limited clearance, meaning they will need to take extra precautions to work safely along the line. This can be found near tunnels, overpasses, or where either width clearance or height clearance is low.

Decommissioned/Unused Signs
| Type | Explanation | Image |
|---|---|---|
| "SLOW" sign | A sign with the words SLOW means that drivers should slow down as soon as possible. This was placed near stations and crossings. |  |
| Type | Explanation | Image |
|---|---|---|
| Old "S" Car Stop Marker | This version of the "S" Car Stop Marker was used at older stations. |

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 multiple SPAD traps in the game, none of them are currently preceded by SPAD Trap Indicators (signs or signals).
