2. Railroads help reduce congestion on U.S. highways. Because rail cars can hold three to four truckloads of freight, just one train can take more than 300 trucks off the road. Think about what happens when you multiply that number by a year's worth of shipments – that's a lot of trucks!
Of that, each loaded car weighs 143 tons apiece with 100 tons of coal in each car. This is exclusive of each locomotive that could weigh up to 415,000 pounds apiece. Depending upon the daily fluctuations of coal as a commodity, the value of the coal itself could reach as high of upwards of $1 to $1.6 million per train.
Trains would consist of an average of 60 cars and hence, have a carrying capacity of 4,440 tons. A modern railcar has a gross capacity of 286,000 lbs or 125.5 tons moving in trains consisting of 100 cars or more, yielding a total carrying capacity of 12,500 tons, an increase of over 181% in carrying capacity.
It found that passing trains carrying coal add on average 8 micrograms per cubic meter of air (ug/m3) to ambient PM2.5 pollution. That is 2 to 3 ug/m3 more than freight trains contribute.
No, they were phased out many decades ago on commercial railways. There are still some steam trains running on preserved railways for steam enthusiasts. Coal-fired steam engines were made uneconomical on non-electrified routes by diesel engines. A diesel costs vastly less to operate, is more reliable and safer.
