submitting an application
Submitting an Application

Applications must be made into the system at the latest “by mid-day the day before” the planned date of the work. (The actual cut-off time is 11.59 hours, 10 hours before the start of the Daily List issued to Signallers for the twenty-four hours commencing 22.00 hours the same day)

Applications should contain as much detail as is relevant to the work being carried out. This will avoid confusion and ensure a timely response to the request.

Many applications are rejected through lack of information or incorrect/incomplete details in the request.

Reference should be made to the Sectional Appendix and Signal Diagrams to ensure the accuracy of the input details (names of lines, protecting signal numbers, point numbers etc), Hazard Directory to identify Red Zone Working Prohibited locations, restricted sighting etc and to the Green Zone Guide to determine the availability of green zones BEFORE making an application.

Reference should also be made to the Weekly Operating Notices (WON) to ensure that the application does NOT conflict with any existing planned items.

Examples of how to complete applications and an example are given in the following pages.

GZ Planner Guide Issue 03


Useful Hint

Planner’s Guidelines

  • If you require to work in more than one area of the website at the same time then pressing Ctrl + N will open up another window.
  • This is best utilised after Log On and means that you do not have to Log On again.
  • T12’s Can only be taken from a Controlled Signal. Many applications are Rejected through this error.
  • T2’s Cannot be taken from GPLS, IBH Signals or Auto signals without keying facilities.
  • T2H applications cannot be granted from Barred Signals.
  • If unsure from the Signal Diagrams what type of Signal is shown check with either a competent Signal Technician, Signalling Manager/Engineer, GZAC or the controlling Signal Box.
  • The “Flexibility” options now mean that if for legitimate reasons it has not been possible to take up an booked T12/T2 in the date of plan – the Planner/Manager can in agreement with the GZAC have the original item re-dated into the following day.
  • Communication by phone or face to face is required from the Planner/Manager to the GZAC to get an application re-dated. If agreed the system generates an new accepted application email containing details.

GZ Planner Guide Issue 03


After successfully logging onto the Green Zone Access Website you will be presented with this screen where messages are posted on a regular basis. Please take time to review the messages as they may be relevant to you. Click continue to proceed to the On Line Booking Form.

GZ Planner Guide Issue 03


FIRST, check that the correct GZAC location is set for the application you are making this sets the Signal Boxes dealt with.

Your details and employer are automatically entered here.

Enter the date and times for the application (duration is self calculating)

State the location of the work -use Sectional Appendix locations (also state ELR for clarity, if known)

Having set the GZAC location for the application you are making this then links to the drop down boxes containing the Signal Boxes dealt with

GZ Planner Guide Issue 03


State which line(s) are to be blocked – use the Sectional Appendix description.

Enter the location limits at each end.

Enter the Controlling Signal Box for the Signals used to protect the work from the drop down list. Either, click on the arrow and select or type the first letter of the name then use the drop down arrow.

If the box is not listed check the GZAC to Signal Box file at the log-on page. If the box is missing contact the GZAC to have a correction made.

Enter the limits of the Block.

You must specify a Signaller CONTROLLED signal or a signal which can be KEYED to danger with Signallers authority when stating signals.

Specific Action

Unsure that it is TOTALLY clear and unambiguous which line is to be Blocked. This is particularly IMPORTANT at locations where there two lines which can be similarly described as Up Fast etc.

E.g.. the Up Fast (Trent Valley) runs parallel to Up Fast (Birmingham)

GZ Planner Guide Issue 03


Select the method of protection to be used.

If using a T2-D, details should be entered here (this is not a mandatory field)

Answer this question. Blockages which will be given up to pass trains are more likely to be accepted. (Green Zone Planner site requests are for NON-DISRUPTIVE T12/T2 access

GZ Planner Guide Issue 03


Answer this question. The detail is available in the Hazard Directory. If the area is Red Zone Working Prohibited the work MUST be done in a green zone.

(Unless a position of safety is being created within it by blocking a line for staff to move into for sites where the cause of the RZP is no position of safety or there are more than 3 lines to cross)

Give a reasonable description of the work to be done

This is the latest date the work must be completed by.

Set the work priority

GZ Planner Guide Issue 03


If the application is linked to another application state the number of it here.

Please, ensure you state the correct number.

Eg. You may be planning for work to be done on site under a T2 BUT to reach the site from the access point requires a T12 to get there and another T12 to get back to the access after the work is complete.

You may wish to print your application for your records before submitting the request.

GZ Planner Guide Issue 03


When ALL details have been entered Click here to submit application.

The system checks that details have been entered into all mandatory fields. You will see a message and be taken back to complete any missing details.

Note, the system does NOT check that the details entered are correct – that is the person inputting responsibility.

When the completed application is submitted to the Green Zone Access Manager they consider it taking into account the information given and possible conflict with other planned works. If two different applications are made for the same area then communication will be encouraged to see if both parties can work together. If this is not possible then priority will be given to the most urgent application and alternatives offered to the unsuccessful application.

Illustration Example

explanation of example application
Explanation of Example application

The example block was taken from L835 pts and not L239 signal as this affected the Down Slow at the same time and was unnecessary as the area of work fell well within the planned block.

GZ Planner Guide Issue 03


A note of the reference number will enable planners to check on the status of the applications submitted

GZ Planner Guide Issue 03

Helpful Hint

If the same application is required for several occasions - to prevent repeat inputting of Data it is easier to submit the completed application. Then click on the back button. This will bring the application back and all that needs to be done is to alter the dates accordingly. Then click Submit and make note of the reference number given. This can be repeated as many times as required.

GZ Planner Guide Issue 03

viewing time slots

A screen similar to this will appear showing any applications made for the defined search made.

This shows that between 0100 and 0500 from 09th to 13th August there is the possibility that a blockage will be in place between Northfleet and Denton.

From October 2005 this screen shows ALL applications made by ALL planners.

GZ Planner Guide Issue 03


Click here to Logout of the system when you have completed using it.

Clicking on the Contractor Request tab enables the user to view applications submitted by other areas of the same Company. Again this aids planning in that it prevents clashes and needless wasted time applying for an area already blocked. On the other side of the coin it may be possible to work within the same block

See also next page for helpful hint after clicking on view.

Click here to view details and print documentation if required.

Click here to delete an application. If you find that the work planned for an application will NOT take place when originally thought – cancel the application so others may gain access.

NOTE – at the moment this can only be done BEFORE application has been processed Contact the GZAC to delete a processed application

GZ Planner Guide Issue 03
