Countries and Vehicle Types in ERD.

Each vehicle in the ERD stock table is allocated to a particular Country and is also of a designated type. You can add your own Country designations and vehicle types to the ERD system if you wish. In the combined version eleven countries have detailed stock records and a further ten countries have certain private locos allocated.


When Countries is chosen on the ERD Menu a window appears which lists the defined countries and their abbreviations. To add new countries to ERD you simply add them in the bottom blank row of the window. So if, for example, you visited the USA or China, you could add these countries to ERD and input your sightings. The window is shown in the following screen shot together with the window which is accessed when you press the Statistics button.

The Country Statistics window as shown below lists all the countries in ERD together with numerical totals of the quantities of vehicles in each country plus the total you have seen and been hauled by. Percentages are also shown so that you can immediately see which country you should be giving the most attention too. Hardcopy reports are available to print this data if desired.
