+# Your Assignment
+# ---------------
+
+# In most circumstances like this, there's a sort of MessageBoard. Let's create
+# the idea of a MessageBoard class that both the engineer and the conductor know
+# about.
+
+# 1. When the conductor sees trouble, the conductor tells the `message_board` to slow down
+# 2. When the engineer slows down, the engineer tells the `message_board` `confirm_slow_down`
+
+# Use whichever mocking tool you liked the best or are interested in. If you
+# don't know what to choose, go with RSpec.
