The locomotive also received many upgrades, including a new boiler, cowcatcher, domes, and smokestack. He reportedly drew his sketches from the cowcatcher of a locomotive train. Davenport also invented and built the first locomotive "cowcatcher" and cab in Massillon. The solid EMD cowcatcher has been discontinued. Damage was minimal, mainly being confined to the destruction of the cowcatcher. It also initially retained its original cowcatcher. Later, the C&A also added a pilot ("cowcatcher") to the lead truck. Some WAG-9(x)s are fitted with a solid cowcatcher while others are fitted with grilled cowcatchers. The "Cow Cow" in the title referred to a train's cowcatcher. A steel pipe or "boiler tube" pilot replaced the original wooden type of cowcatcher.
