Filename syntaxes (or name formation) in Trainz assets are heavily restricted for compatibility reasons. As filenames are not displayed to end-users, there is no need for localization support (File and directory paths) or other format class characters.

Specifically, filenames within Trainz must obey the following rules:

  1. Filenames must not begin with a space (' '), a period ('.'), or a tilde ('~').
  2. Filenames must be at least one character long.
  3. Filenames must not end with a space (' ').
  4. Filenames should be kept to a reasonable length. No fixed length is currently enforced, however if compatibility issues arise at a later date N3V Games may add length limits.
  5. Smart quotes, accents, umlauts and other non-ASCII characters are disallowed.
  6. Filenames must consist of the following ASCII characters only:
'a' through 'z' lowercase
letters
'A' through 'Z' uppercase
letters
'0' through '9' numbers
hyphen  ' - ' 
ampersand  ' & ' 
comma  ' , ' 
plus  ' + ' 
apostrophe  '  '  ' 
period  ' . ' 
underscore  ' _ ' 
dollar  ' $ ' 
space  '   ' 
open parenthesis  ' ( ' 
closed parenthesis  ' ) ' 
tilde  ' ~ '
