The main difference between the two is that a bus often travels on a fixed route while a coach is the means of transport for people who travel to a relatively faraway place.

23. Weather conditions have a strong influence on transport
Weather conditions have a strong influence on transport. It is very important that drivers are aware of weather conditions such as wind, rain or a typhoon. Ship captains need to know about wave conditions. Airplane pilots want to know about the condition of the atmosphere.

24. Automobile drivers and railroad engineers have to know if rain or snow is going to fall. Without correct, timely weather information, transportation equipment cannot be safely operated. That's why operators of such equipment and passengers may pay very close attention to weather reports.
