Today William was asked to assist in shunting goods and passenger trains. The only instruction he had was that no more than two of the same train may be parked next to each other. This goes for both rows and columns.
Hint: every row and every column must contain 5 icons for both engines.
Can you help William to do this job? You can copy and paste the icons, or use grid paper with X and O's for example.
