Cut out the main section of the train. Form the rooftop of the train into a curve by rolling the paper against a round pencil or metal rod. Fold the sides down and the tabs at the ends inwards.
Cut out the bottom floor of the train and fold the tabs upwards. Make sure the bottom piece is flat and straight. Then glue the floor section inside the walls of the train, so that the floor is lined up with the bottom of the walls and the ends marked 'front' and 'back' match (fig. 1).

Next cut out the ends of the train. Curl the ends to match the curve of the floor at the ends of the train by rolling the paper against a round pencil or wire. Also, curl the top the the car end slightly so that it will match the curvature of the roof of the train car.
Glue the ends of the car to the front and back with the tabs inside (fig. 2).

Cut out the wheels and fold into a small box (fig. 3).
fig. 4
Glue the wheels at the front and back of the train car, in the gray boxes on the bottom of the floor (fig. 4).
At last your model of the IRT train car is finished!
