Train

After the Railway is opened (First summer after the Earthquake, above the Carpenter).

Occasionally an announcement will appear stating a train is passing through. You can watch the train passing, and attempting to strike the train with a tool will do minor damage to your character.

This needs confirmation but I believe I was able to knock coal from the coal cart as it passed.

While the day's the train passes are not set, there will be one or two a week typically.
