# SBRail: Model Railroad ScreenSaver

SBRail is a ScreenSaver for Windows-95. You must have DirectDraw installed on your computer to use this ScreenSaver. If you do not have DirectDraw and need it, I suggest searching the web (www.shareware.com is a good place) for "DirectDraw" or "DirectX".

Specifically, this ScreenSaver displays a scrolling train on your screen. The cars in the train are randomly selected and put together.

There are two display modes:

- Normal: The trains are displayed "transparently" over a background image. Several background images are included. This requires a fairly good video card capable of hardware transparent blitting, double buffering, and a decent amount of video ram.
- Fast: This displays the trains over a plain blue background. This is good for use with older video cards that don't support transparent blitting and/or double-buffering.

SBRail will attempt to automatically choose the correct mode depending on your hardware configuration. However, you can override this choice by choosing 'Setup' from the Windows ScreenSaver Configuration. If output is too jittery or blocky and you're operating in normal mode, then you may wish to force it to fast mode which should reduce the jitter.
