Answer 2

You can also look here http://www.spikesys.com/Trains/Signals/ for info about historic railroad signals. I work in Boston, so the present CSX railroad uses signals from the olf New York Central railway, the old Penn Central railway, and some old New Haven signals just for fun. In other parts of the country, C&O and Southern RR signals are in use.

Railway signals are like road traffic signals but with much more. They not only tell you when to go and when to stop, but also the speed you should go, and what the track conditions are ahead (trains or broken rails, will you be turning off the main track in a few miles, etc.)

There are two types of signals - remote or permissive signals, which are the ones in the middle of nowhere that tell you what's ahead, or Home signals which are located at switches and tell you to stop or whether you will be diverting to another track.

Answer 3

You mean the signal?

Red = Stop
Single yellow = prepare to stop at next signal
Double yellow = slow down and prepare for a single yellow at next signal
Green = all clear, full speed ahead

Remember it takes a long time for a train to stop, so they need advance warning of an approaching red signal

Answer 4

Almost same as road traffic color. Only in road traffic Yellow does not have much significance. In rail it is ----- get ready to stop in the next signal.

Answer 5

red means stop yellow means be prepared to stop and green means keep on going no trains ahead.

Answer 6

if they are red that means there are no trains coming. if they turn green then there is a train coming.
