This is one of the serious problem that arises because if you set your monitor with a high resolution with high frequency, then the monitor doesn't display anything as it's frequency is out of the rang or limit of the monitor's actual resolution capacity. Each monitor will have a limit of max frequency that is said to be the Refresh rate (for each and every resolution setting the display is refreshed.) When high resolution is set with high frequency that is not supported by the monitor, it then display a message like "frequency out of range". If you press ESC key within the few seconds of this setting, it will revert back to its initial resolution. But if you continued with the setting of same High resolution with High frequency, the monitor is not going to display anything because its frequency is out of the range. Most of old monitors like CRT's etc doesn't support 1024×768 at a refresh rate greater than 60Hz.

Your PC video resolution is too high for the monitor to work.

the monitors resolution range is only to 1280X740 or 780
and your video card may also need an upgrade.
The game may require a higher resolution that is not compatible with the the devices mentioned.

Try booting to the ENABLE VGA mode off the F8 menu if you can get to the desktop and then you can go to display properties and see if you can reset the resolution to normal. If no go, try updating the video driver

It sounds like the frequency referred to is the monitor's frequency. If it's an LCD monitor, the frequency is usually 60Hz. If you are using a VGA cable, it's guessing the frequency and has guessed wrong.
The other possibility is that the Railroad Tycoon game sets the screen resolution and frequency to something your monitor is not capable of displaying. It sees a nice graphics card and shoots the settings to the top of the range. If you can change the settings before playing the game, you might get it to work.

reboot the system by pressing F8 if your using windows OS and select last good configuration.

you can try also selecting Enable VGA mode (press F8 while rebooting and select ENABLE VGA mode).

hope this helps, please rate.
