Here is a small simple utility which will enable you to use a joystick instead of the keyboard to drive the trains. It makes it possible, indeed, to emulate keys of the keyboard by means of a clear interface making it possible to allot to the lever and the buttons a key. It will be thus easy for you to allot, for example, the letter D with a movement of the lever (forwards) and the letter Q backwards. I tested this small program with a joystick Logitech Attack 3, that functions perfectly well! It should be noted that there is no installation, to place the achievable one where you want and launch it!
