Authentic recreations of the traditional Railway Signalbox

Welcome to the home of Blockpost Signalling Simulations

Latest News, January 2019

   Work continues on our next simulation - Crow Nest Junction - but there has also been a further setback to this as a rather tricky bug has appeared in the graphics.  In response to user feedback, the opportunity was taken in this simulation to improve the way in which track circuits are displayed on the illuminated diagram.  The new approach is certainly better looking, but the bug is causing spurious "occupied" indications to appear when the display is zoomed.  Work is continuing to try to bottom this, after which, there remains only the timetables and documentaion to complete - though these are not tasks to be under estimated...
Apologies that things are not moving faster, but please continue to watch this space and in the meantime...

June 2018:--   A revised version (v4.421a) of Exeter West (Basic version) has been uploaded.  The changes are minor to fix very minor bugs, but could I ask users to download and install this version at their convienience.

Product News, October 2017

Exeter West Advanced Version -

now available for purchase as an add-on pack for existing customers.

After a two year development, including extensive testing in the preserved Exeter West signalbox at Crewe, an "Advanced" version of our Exeter West Simulation is now available as an add-on to an existing registered copy of Exeter West.  The current Standard Version incorporates a number of simplifications which were introduced to enable anyone with a basic understanding of mechanical signaling to be able to get to grips with this complicated box.  The Advanced Version however, removes these compromises with the result that it fully models all aspects of the original box.  Of course, this means it is very challenging to work, and for that reason, it will be available ONLY as an "add-on pack" to an existing licensed version of the Exeter West simulation.  This means that purchasers will continue to have access to all their existing timetables, scenarios etc whist also having a new 24 hour weekday timetable containing over 400 movements which fully exploits the new Advanced functionality.   Please see here for details

The Advanced version will come with free lifetime-upgrades - both to the programme and to the timetables -  because it will exactly mirror the programme which will be running the preserved box.   

Timetable Editors are now available for purchase

In response to many requests, we have been busy developing Editors to enable customers to create and edit timetables to run on our simulations. The first of these, for Portcreek Junction, is now available for purchase. 

Please note that the Editors will ONLY work with Registered copies of the simulations - they cannot be used with the demos.  If you therefore would like to create your own timetables, but have not yet purchased a full license for Portcreeek, you should do so before purchasing a Timetable Editor.

Simulation developments.

Our next completely new simulation will be Crow Nest Junction - not the recently-closed plywood wonder, but the former L&Y box of 91 working levers. The simulation will be set in the late 1950's when the area still featured extensive freight operation to and from the Liverpool docks, the Lancashire coal fields and local manufacturing industry.  Coupled with some very difficult gradients, this necessitates the use of Banking locomotives from the Wigan direction. Add to this busy holiday traffic to the seaside resorts of Southport and Blackpool (yes, a number of these did run via Hindley!) and operation is quite interesting!

Currently, all the code is completed and tested and the prototype timetable information has been acquired. All that remains therefore is to compile and test the timetables and this work is planned to be undertaken during this winter.

Improved user interface.  

We have updated the simulation screen to allow the Train Information windows to be resized by dragging the side and top borders. This long-requested feature enables users the flexibility to choose to allocate more or less screen-space to the simulation display - particularly helpful for those with unusually low, or high resolution monitors. The arangement also allows the simulation to operate fully even when the window is "restored down" - particularly usefull if you wish to run the simulation whilst also displaying the "help" files, Train Register, Bell Code or Locking Information at the same time.  All future simulations will include this feature and existing ones will be updated in future versions.   

Our Portcreek Junction has been already been updated with this feature - please download and install it to see the effect. Remember that if you have purchased a License, all your registration details are preserved when you update.

Licences for our

Portcreek Junction, Gloucester Road Junction, Barnham Junction, Ford (Sussex),  Yapton Crossing and Exeter West simulations remain available for purchase on line.

Demo versions of all of our simulations are available for free download
