Limited Express SOS, trying to find

Hi,

What a great site, I've finally found the name of a game I played years ago. All I could remember was what you did in the game, and the filename I used to launch the game, exp.exe. So using the search I found it, (in conjunction with the screenshots). It's called Limited Express SOS, whcih apparently is a Japanese game, so it may also go by a Japanese name.

I can't see it in the TOSEC list, does anyone know where I can download this game, or what the possible Japanese name would be?

Found it under the name "Stop the Express".
