At the top of this please there is a search box for finding trains. "enter train name/number" is written here. Replace this writing with the train number or the name of the train. As you start writing the name or no. of a train, train suggestions will appear below. Select the train you want to know about by clicking on the train name given in the list of trains suggested. Then click on " train details" tab just below the train search box. This leads you to the main page of the train where every detail about the train including the coach composition is given. For your convenience I post here the main page of train no. 12370 Kumbha Express and put the area which shows the coach composition within a rectangle.
