How to build a brick steam train

The finished brick steam train: a famous green steam locomotive with a tall smokestack, big wheels and a coal tender full of coal

To build a brick steam train, line up black wheels under a long gray frame, build a coal tender at the back with black coal on top, make a green boiler with a black nose, add yellow bands, a dome and a tall black smokestack, then a red driver's cab with light-blue windows. 70 pieces, 5 steps, ages 7–13.
