Three SL class coaches in 22487 express are S8, S9, S10. But in display board of coaches, it is numbered as 1,2,3 which very confusing.
S3 is actually S8, S2 is S9 and S1 is S10.
I was traveling on this train on Saturday and found all passenger were confused. They were running on platform from one end to other another to find their coach.
