Freight train
Also: goods train, freight, freightliner
A train carrying goods, sharing the same tracks and signals as passenger trains.
Freight trains carry containers, stone, steel and more. They have headcodes, schedules and TRUST reports just like passenger trains, and their headcodes start with 4, 6, 7 or 8 depending on how fast they can go.
They don’t stop at stations for passengers, so they never appear when you search for a trip.
