Where did we get this geeeeenious idea?
Any guesses?Write it on your scratch

yourself
Why are there time zones???
• Caused by the r&r boom• Back then, towns kept their own time• Sun directly over town = noon– How is this a problem state to state?
• 1883, all railway clocks set to a new standard to make travel more consistent & easier
• The country caught on!
Industrial Growth1865-1914
• Same time westward expansion is taking place• While many moved west, a lot
stayed to build up the economy
Railroads Spur Industry• At first, railroads (R&R) were
locally run• Domestic lines couldn’t join
because of differences in gauges
• Gauges: width of a railroad track
Improvements to railroads
• 1886: railroads in the south adopt northern gauges – (13,000 miles of track change)
• Railroads now create a network• network: system of connected lines– Shipping: freight cars become
universal • shipper pays only 1 fare for whole trip
Westinghouse Air Brake
• 1869, allows locomotive engineer to stop all railroad cars at once. – Increases safety– Allows longer trains– Allows faster trains
Pullman Sleeping Car• Cars with convertible benches for sleeping &
lavatories
• Dining cars• Waiters and conductors to help passengers
