Railpower Technologies is a subsidiary of R.J. Corman Railroad Group that builds environmentally friendly hybrid Green Goat and Genset switching locomotives, founded by Frank Donnelly and Gerard Koldyk.

The company was founded in 2001 in Vancouver, British Columbia, and incorporated an automotive propulsion system into a new hybrid yard locomotive, dubbed the "Green Goat."

As a result of the drop-off in sales, Railpower entered bankruptcy in early 2009, and was purchased by the R.J. Corman Railroad Group during the summer of the same year.

[3] On June 18, 2009, R.J. Corman Railroad Group announced that it had completed its acquisition of Railpower's assets,[4] although none of the company's liabilities.

As a result of the acquisition, customers of Railpower were forced to renegotiate servicing contracts with Corman, as the warranties on the locomotives ceased when the old company was purchased.

Created from older locomotives, these units are deployed in services where there is a lot of idle time, such as yard switching.
