Why do trains go 79 mph?

rather than pay for the expense of maintaining track to a higher standard, and having to maintain the additional cab signals, and having to outfit all locomotives that use the line with cab signals, or ATS, or ATC, the freight RRs simply place the speed limit at 79 mph, and use Automatic Block signal systems.

Modern trains can travel seamlessly from conventional track to high-speed track. They simply travel slower while on conventional track. Passenger service on the conventional freight lines that criss-cross the United States today is limited to 90 mph at best.

Fastest Train in the World – 357.2 MPH The current world speed record for a commercial train on steel wheels is held by the French TGV at 574.8 km/h (357.2 mph), achieved on 3 April 2007 on the new LGV Est.

Slower trains will tend to make flange contact with the inner rail on curves, while faster trains will tend to ride outwards and make contact with the outer rail. Either contact causes wear and tear and may lead to derailment if speeds and superelevation are not within the permitted limits.

With high-speed rail, train travel is always faster than driving. In many cases, it's even faster than flying, once you factor in the whole air travel song-and-dance. And if you do need to catch a plane, trains make it easier to get to the airport.

Fact #8: Trains Travel in Both Directions Tracks aren't one way, so even if you've seen a train traveling east, a train could travel west on the very same track.

MORE DETAILS

“People assume that trains are loud, but that assumption is based on the fact that when a train's gone past them in a station it's noisy. That's because the noise a train makes is mainly projected to either side. When trains are moving directly towards you they are barely audible–until it's too late.”

Unscheduled delays can be caused by numerous events including: mechanical failures, Page 3 malfunctioning infrastructure, weather conditions, excessive boarding times of passengers, accidents at highway-railroad grade crossings and so on (2,3).
