 Take into account that the first line must be blank (before the include line).
 
+In case of more trainsets residing in the same folder and requiring the same 
+additional .wag or .eng files with exactly the same contents, it is useful to 
+use the conventional filename ``[[SameName]]``.
+OR will replace that filename with the filename of the file containing the Include 
+statement. So, in the case of the example above, instead of::

+the following can be written::

+    include ( ../[[SameName]] )

+This way all additional .wag or .eng files referring to similar trainsets would 
+have exactly the same contents, drastically reducing editing time.
