Leonard enjoyed playing with his train set quite a lot. The trickiest bit was near the end of a long downgrade, where the train had a tendency to pick up far too much speed. Leonard had to be particularly alert and ready switch off to a side rail to save the day. Fortunately, the switching went without a hitch, and the train barreled past on its new southern course. He leaned against the switchbox and watched his train roll past, whistling happily. Seven minutes later, the two trains collided head-on at full speed with more than hundred passenger casualties.
