Create an Emergency Speed Restriction

Top Section

Reference Number (refnum)

Each ESR has a reference number. It is constructed as follows;

XXXX nnn{a}.yy

XXXX = Route specific prefix (AICC = Anglia, etc)

nnn = Annual sequence number, starts over at 001 each year on 1st January

yy = two digit year, e.g. 24

a = the amendment (if any), A, B, C, etc

AICC 123B.24 is the 123rd restriction of 2024 on the Anglia route and has been amended twice.

Top Level Information

Line Cards

Primary Line

The Primary Line MUST contain the Commencement Board!

ELR – this is inserted automatically based on the ELR selected in the top section. It cannot be changed
Track ID – 4 digits, for example 1100 = “Up Main” …. the impacted ELR is now highlighted on the map
Line – we automatically apply the standard description based on the Track ID given. You are allowed to change this but we suggest otherwise
Direction of Travel – select from Up Direction and Down Direction. This affects the sorting order of Boards!
Add Boards with their mileage — to enter the Miles and Chains you can simply type the numbers and the “.” will be inserted before the final two digits. Therefore, typing “1234” will give you “12.34” or “12m34ch”

HINT: pressing the ENTER key has the same effect as clicking on “Add Board”

NOTE: after adding a board the next in sequence is automatically selected

NOTE: after adding a board it will appear on the map – if the mileage is valid for the ELR and Track ID

Additional Line Cards

If you have boards that is not on the Primary Line (ELR or TrackID), you must add an Additional Line

Click on the button labelled “+ Add Additional Line” if there are boards placed on a different ELR or Track ID (direction). This is common where the restriction comes into effect near the end of an ELR, also for bi-directional track.

This section is essentially the same as the Primary, except here you can choose the appropriate ELR.

Remarks Section

There are two fields for adding comments. "Notes to Drivers" will appear on the Notice that is used by Operating companies.
