The train tracks that criss-cross the US showcase a different side of the nation, discovers Sophie Barclay.
Rail travel was once a grandiose affair. After its heyday in the early 20th century, rail enjoyed one last hurrah in the 50s, when the latest models of luxurious, sleek rail cars were the top choice of travel for musicians, sports and film stars (a la Some Like it Hot). Many of these beautiful 1950s rail cars were lost, pulled apart or destroyed when America's love affair with the motorcar saw rail relegated to a second-class citizen.
In 1971, Amtrak, the national rail carrier, took over the intercity rail service, operating a no-frills service across the country. It now connects more than 500 destinations across the States, traverses the Californian Coast, links tourist hotspots like New York and Niagara Falls and even delivers travellers over the border to Canada.
Trains also offer carbon-conscious travellers a chance to deviate from fossil-fuel hungry transport. Amtrak's services are 30 per cent more efficient than car travel and nearly 20 per cent more efficient than domestic airline travel. Impressively, Amtrak was also the first transport company to sign the Chicago Climate Exchange, a legally-binding greenhouse gas reduction and trading programme.
Its comfort, superb views, relaxed pace and city-to-city convenience (no more mucking about with airport taxis) means train travel is perpetually popular with travellers without time restrictions.
