Not true, only one land based vehicles have ever broken the sound barrier.

1. Thrust SSC – 771 mph
The current world record holder for the fastest land-based vehicle of all time is the Thrust SSC. Engineers were able to achieve a maximum top speed of 771 miles per hour with the Thrust SSC, which made it the first land vehicle to ever break the sound barrier. The record fell on October 15, 1997, in the Black Rock Desert in Utah. The Thrust SSC was powered by two Rolls-Royce Spey turbofan engines, which are also used in fighter jets. The two engines supplied the vehicle with 110,000 horsepower, burning 4.8 gallons of fuel per second. The Thrust SSC has held the crown since 1997, but engineers are hot on its tail. Until another vehicle is able to reach mach-level speeds, the Thrust SSC is the only vehicle to achieve such a feat.

Question: I m planning to travel around the US, using Amtraks USA rail pass. Do you have any suggestions on how to make my trip enjoyable?

It is easy to look up train schedules. In the western half of the country most are just ONCE a day.
If you want to stop off and explore some place. For example just past Spokane is Glacier Park. You plan your overnight things and book space for a next ride a day or two later. DO NOT ASSUME there is space for next train.
You DO NOT need a room for your entire journey. Make circle tour direction is your choice. Plan for few stopping places along your way and enjoy the sites from SEE Level.
Many Amtrak Videos on You tube to get a peek at what you might see along he way.
At your stop over place you move things from your big suitcase to your carry on stuff. Have some cash in smaller Bank Notes. No need to buy a Soda with $50 bill or your credit card.

Explore on the train and take advantage of the view cars lounge and dining car. DO NOT HOG the seats others too want to see the views. If you want you are able to meet others from around the world also exploring by train.
Use a little planing obviously the view at night not quite the same as when the sun is up. Dress comfortably for on the train. Take only what you need for the next few days as carry on stuff. The rest of your luggage you can fetch at your stop overs.
If you can take some small travel games with you. A travel chess board a deck of cards gives you something to share with a fellow traveller.

Most train routes are two to three days in length. Your choice how much of your two weeks you spend on the train or stopping off at a few places for a day or two to explore more.
You may want to use the HUMAN to help you book your train tickets. It gets a little complicated when you stop over. 1-800-USA-RAIL 1-800-872-7245

Look at some of these packages for ideas of things you can do as part of your exploration.

If you are in or near Seattle maybe next year you explore another train system.

Investigate one and two day bus tours at your stopping places for additional exploration off the train route.

Question: How do electric locomotives raise their pantographs without power?
