Tow Plow - Why would you have a tiny plow on the front of your truck when you can just tow a plow behind you? This giant plow can remove much larger areas of snow than a regular hook-up plow will ever do.
Airport Plow - With a plow that's longer than the truck attached to it, this can clear entire runways before any flights get delayed or cancelled. This comes in quite handy during holiday flights.
School Bus Plow - When it starts to snow, many schools just cancel classes. With a school bus that can also plow, there can be less cancelled classes much to the disappointment of students.
Three Plow Truck - Instead of just one snow blower, this has three snow blowers. If snow gets to five feet or higher, this can get rid of it very quickly.
Train Plow - With trains having to bring commuters in to school and work, the tracks need to be cleared immediately. This train can not only clear the tracks of snow, it can bring passengers along while it's doing that, so no one will be late.
