Keep in mind though eastbound and westbound trains will not always arrive at the same time to an intersection.Trains are expected to run as often as every 5 minutes to every 3 minutes and 10 seconds at the busiest times, potentially even more frequently. That is plenty of time for cross traffic and left turns to be made.
A typical traffic signal cycle length for motorists ranges from 45 to 120 seconds, but can be as short as 30 seconds or as long as 180 seconds.
So technically, it will be in the range of every 2.5 - 5 minutes, and every 95 seconds to 190 seconds.
