Columbia Locomotives prides itself in doing things differently.

Three things worth knowing up front:

01 / Unrepresented

First and only American team in the space

The U.K.-based iMechE Railway Challenge is the only locomotive engineering competition in the world. We want to be the first American team to compete against its incumbent international universities and companies.

02 / Unprecedented

Battery-electric traction architecture

The United States boasts a staggering 30,000-strong fleet of locomotives, 99% of which are diesel-electric. In an increasingly electric world, we want to compete with the latest and greatest electric traction technologies.

03 / Unwavering

Rapid prototyping for railways

We pride ourselves on our rapid prototyping culture. Rapid prototyping with inexpensive resources encourages first-year university students to dive right into industry practices and gives members the opportunity to fully own a project, no matter how big or small.

We ask for commitment, not prior experience.

Members work on a real machine alongside students across mechanical, electrical, software, manufacturing, and business operations divisions.
