Be a professional shunter by guiding the train to its correct destinations! In this game, your task is to lead the train to pick up the resources according to the orders, and deliver them to the factory within the time limit. The game starts with a train running on the track, with some switches and traffic lights along the track. The current order is shown at the top left corner of the screen, and the train needs to pick up the exact resources according to the sequence of the materials. You may click a switch along the track so that the train can turn to another track and get to the collect point of resources whenever necessary. The train can load up one cart of resources each time, and you may need to return in order to pick up the accurate number of resources. After collecting the materials, click the traffic light next to the factory so that the train will stop to deliver the resources upon arrival. If you have picked up wrong resources, you may click to remove them when the train stops. Continue the process until all orders are completed, and you can proceed to the next level. The faster you complete a level, the higher your score, and your score is reflected by the amount of money collected at the top right corner. A passenger train may enter the track from time to time, and you need to guide it to the correct destination safely. Remember to seize the time and avoid crashes or you will be fired!
