Mathews points to research showing that trains emit the lowest of CO2 per passenger mile at 177 grams per passenger mile. Buses come in at 299 grams per mile, second-worst only to cars at 371 grams.
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.
In the coming years, Amtrak will invest over $50 billion into modern trains, enhanced stations and facilities, new tunnels and bridges, and other critical infrastructure upgrades. These generational investments mean we're no longer only a passenger rail operator.
Their speed, however, will be limited by the complexities of the 457-mile route, which is old, curvy and carries a mix of freight, commuter and intercity trains. Most Amtrak trains travel between 110 mph to 145 mph in the corridor, depending on the track and proximity to stations.
Emissions comparisonRail transportation emits about 0.2 pounds of greenhouse gases per passenger mile (55 g/km) when each car is filled with 50 passengers. This figure increases to about 0.5 pounds per passenger mile (140 g/km) when only filled with half that amount.
The simple answer: your Amtrak trip won't be affected by the government shutdown. As we've seen during previous government shutdowns, Amtrak has enough cash on hand to keep the trains running and workers paid in the near term.
Trains consume less energy and produce less harmful pollutants than either car or air travel. Hopping on an Amtrak train will save you gas and daily wear and tear on your car. It also reduces the ever-increasing traffic congestion on the roads and in the skies.

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.
Greenhouse gas (GHG) emissions are directly related to fuel consumption. According to EPA data, freight railroads account for just 0.5% of total U.S. GHG emissions and just 1.7% of transportation-related GHG emissions. Moving freight by rail instead of truck lowers GHG emissions by up to 75%, on average.
