Reference Number (refnum)

Each ESR has a reference number.number which will be added when you Impose. 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

  • Engineers Line Reference (ELR) – Select from the available list (type the ELR code to filter). We do not limit the selection of ELR based on the Route. Be careful to choose the correct ELR!

  • Line of Route – select the LOR from the options that relate to the ELR

  • Location -- see below

  • ReasonLine of Route – selectonce appropriateyou reasonhave codeselected the Location the options are reduced. In most cases there's only one possible LOR at each Location.

  • Speed – use the standard format and select MPH or KPH – e.g. “40/60” or “50”

  • Line Speed (optional) - record the normal Line Speed at this location.
Location

The "Location" gives the driver a familiar place for the start of the restriction. We offer a set of standard LocationLocations based on the selected ELR. In some cases the noteablethese locations might be quite far apart so choose the "between" option.

If there's a Location you wish to add please email us at help@nrsdb.uk - we will need the Location Name, ELR, LOR and Mileage.

Reference Fields

These fields can be changed later without needing to issue an amendment since they are internal Network Rail properties.

Line Cards

Primary

Use Line

the Add Board form to record the position of the various Boards. You must specify the Speed Indicator and Termination boards, other boards are encouraged.

This section remains locked until you have completed the essential References.


You must define the Speed Indicator first. The ELR for this MUST match that selected in the Top Section and so this field is locked.

First select the appropriate TrackID (e.g. 2100: Down Main). If there is only one valid option it will be selected automatically.

You can disable the Map to allow mileages that the system rejects. Since the Map will not work, you must upload your own track diagram.

Additional Line Cards

If you have boards that is not on the Primary Line (ELR or TrackID), you mustNow add another 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.boards.

Remarks Section
