Electro-Motive Division (EMD) FTA #803 of the New York Ontario & Western. This was the locomotive involved in the infamous "Flying Diesel Corp" wreck of 1955 that resulted in a spilled boxcar of Nestle chocolate bars, which were quickly pillaged. Well worth a look-up and read (after you're done buying mugs) when you have some time.
This 11oz mug is microwave safe, dishwasher safe, and made of durable, high-quality ceramic.
