Abstract
A drill jig apparatus configured to be coupled to a locomotive bedplate is presented. The apparatus can include a first member and a second member. The first member can be configured to attach a drill to provide stability while drilling, and the second member can be operably coupled to a locomotive, such as to an engine and bedplate of a locomotive. An engine dowel drilling system is also presented, which can include a drill jig member and a bushing member, and the members can be operably coupled with one another. A method of drilling holes in a locomotive bedplate can include using a drill jig and a bushing to facilitate drilling, and the drill jig can be a conductor-side jig or an engineer-side jig. A kit is also presented for engine dowel installation that can standardize dowels and dowel holes.
