(Highly suggested to read the instructions before playing.) Use the left and right arrow keys to move left and right. Press the down arrow to stop moving immediately. Press the Space Bar to open and close the doors. Note: The rollsign CANNOT be changed. Note: Please open the doors once you click the green flag. All stations mark which trains stop at what station. Look very carefully to see what trains stop at what station. If you do not see a "Q" symbol, that means the train station is not for the Q train. It's suggested you set the throttle to no more than 22. That'll help you determine if the station is for the Q train or not. NOTE: It is your choice. If you want to stop at every station, go right ahead. But if you want to do normal service, follow the instructions above.
