if there's three tracks, then it makes remote sense, but seen as they all show the same, why repeat the - and o ?

In case of burnout.

I can't see it being burnout - what's going to burn out 4 times before someone spots it on rail infrastructure?

Two - stop and two o distant caution.

The stop indication indicates the train must stop at the signal. The distant caution indication means that that the engine driver needs to brake now, to be able to stop at the next signal. This is needed because trains have stopping distances longer than sight distances.

Clusters of signals indicate one of two things:

- multiple tracks

- a set of switches, where the train could be sent in different directions. Only the signal the switch is set for will go to o or |. The others will stay at - stop.

Railroad signals usually cycle in a different order, but it depends on traffic conditions:

Looking at any one signal:

The light is green (or triangle or vertical bar) as a train approaches with permission to proceed.

As soon as that train passes, the light immediately turns red (or horizontal bar). This protects the train from being hit in the rear.

After the train ahead passes the next signal, the signal changes to yellow (or circle). This allows the train waiting at the formerly red signal to advance slowly, but warns it that the next signal is red.

The only time a signal will change from green to yellow is if another train crosses or enters the track at the next signal.

The only time a signal can change directly from yellow to red is if an accident happens that blocks the track. This is because an approaching train must always be given a yellow warning that the next signal is red, unless there is an accident. Then the train must be stopped as soon as possible.

The only time a signal can change directly from red to green is if a switch is changed from a track that is blocked to one that is not.

It's not a distant signal.

It means the same as a regular amber signal, as it applies to LRT which can stop (usually quicker than) simalar to a bus (or at least here in Europe anyway)

Any kind of light rail that cross roads has railroad preemption. When I was down in Baltimore, They used regular RAIL ROAD CROSSING lights and gates. :drool:
