On this line are several trains transporting passengers from staion(No. 1 ) till the end station( No. 24),then each train will continue the journey from side to side(both sides are connected together at each end).I noticed that after each 4 Minutes a train arrives this station from left side toward the right side,one minute later another train arrives the station but to the opposit direction,and so on.
If each train stays in each station exactly one minute( notice that the train at each end will make a curve and return back to that staion,just like a circle).
Howmany trains are there on this line?

The stations are equally spaced, all trains have the same speed,and the distance between any two trains is also equal.Spoiler for Well - some thoughts
