Trains scale better than buses. Each traincar can hold more people than a bus, and trains can be run at long lengths and at higher frequencies than buses. The number of buses required to fully replace the capacity of a full subway line at rush hour frequencies exceeds one per minute.

Bus travel is considered four times safer than taking a train and fifty times safer than riding in a passenger vehicle. The most recent statistics released by the United States Department of Transportation listed 35 occupant fatalities on buses, compared to 12,355 passenger vehicle fatalities in the same year.
Based on the study's fuel efficiency and carbon dioxide emission data, the most sustainable mode of traveling in the U.S. is via intercity bus, followed by trains. Intercity buses use 280.1 passenger miles/gallon, while trains use 79.8 passenger miles/gallon.
According to several studies, the rate of death is lower for travel on public transport than that in cars. For example, in the USA, fatality rate for car occupants were found to be 23 times higher than those for bus occupants, per 100 million person-trips [3].
Traveling SafelyIn fact, when you look more closely at the data, you find that bus and train fatalities occur much less often than airplane crashes. For example, in 2016, there were only 0.7 fatalities per billion passenger miles traveled on a bus versus 1.06 for air travel.
Railroads became a major industry, stimulating other heavy industries such as iron and steel production. These advances in travel and transport helped drive settlement in the western regions of North America and were integral to the nation's industrialization.
It is very true that when moving on flat ground in a straight line, trains on steel wheels and rails are the most efficient form of transportation. Rolling on steel rails reduces rolling resistance and traveling at slow speeds (compared to jet aircraft) reduced the force of air resistance.
By leaving the car at home, a person can save up to 20 pounds of carbon dioxide emissions every day. Buses keep the air cleaner. Passengers riding on buses means fewer car drivers, lessening the number of vehicles to clog up streets and freeways.
Coach bus drivers are reliably attentive and experienced. Keep in mind, every hour spent on the road is an hour of professional work, and drivers are under contract to keep their passengers safe and comfortable. Driving a bus is different from driving a car in many ways.
The word bus is short for omnibus, which means “for everyone.” Bus was first used in this sense in the 1830s, its everyone meaning referencing the fact that anyone could join the coach along its route, unlike with stagecoaches, which had to be pre-booked.
Riding the bus is often much cheaper than taking a flight, and allows people to evade airport hassles. But trips can take far longer than advertised and disruptions can hit buses as surely as they hit planes.
The cleanest modes of transportation are walking and biking. Walking to and from the store will not only get you closer to your daily step goal, it will not contribute to air pollution. If you biked one kilometer to the store, your bike's emissions score would be 8.
If we take an overall view of the transport sector, 71% of transportation related carbon emissions come from road users, whereas only 1.8% of emissions stem from rail travel. So in absolute terms, trains are responsible for a lot less emissions than cars.
These massive, track-mounted vehicles, which use a diesel generator to power electric motors and move rail cars carrying cargo or passengers, are major polluters, responsible for a growing share of the emissions that increase cancer risk, shorten lives and worsen smog across California.
Trains. Besides walking and biking, traveling by train remains one of the greenest and most environment-friendly options when getting around. Regardless if electric or diesel-powered, trains emit between 66 and 75 percent fewer carbon emissions when compared to cars and airplanes.
