Railroads made travel between towns and cities easier and faster. Before the popularization of railroads, each area had it's own time based on noon being when the sun was straight up in the sky. This led to some confusion about travel times and such, so they made set time zones for areas to group together under.

The railroads created the time zones and the concept of standard time, to simplify the publication of their timetables. Before this every town was on a different local time, determined by sighting the peak of the sun's path in the sky as being local noon.
before railroads,each community determined it's own time based on how the sun travels.this was called solar time. it however caused problems for people who scheduled trains crossin different time zones
To measure time. To measure time. To measure time.
An accelerometer is an instrument to measure acceleration, which is the change in velocity per unit of time.
Before railroads, everyone used the sun as their source of time. With railroads, people needed a standardized time system because of shipping and settlers moving from east to west because the sun rises and sets a different times on both sides of the U.S.

Acceleration.
they used sundials to measure time so yeah
Central Pacific Answer: The time zones were actually started with the railroads. The railroads had to be on time and before the universal time zones were initiated, many towns and states, ETC had their own time and railroads had a big problem trying to keep accurate time. The railroads came up with the idea of having 4 time zones for the united states.
One of the first reasons early people needed to measure time was to know when to plant and harvest their crops.
Change over time.
Not, usually most of the time the railroads have their own police.
