I can understand your frustration not knowing the terms. I didn't know what a PFI train was either until I google it. PFI is a Pixel Frieght Train. In simple terms it is what transports cargo like wood, glass, nails, and bricks. Basically you would have use a steam locomotive with the power of 4, and add 4 different cargo to achieve the reward. Hope that helps.
