The ALCO RS-27 (specification DL-640) is a diesel-electric locomotive built by ALCO between December 1959 and October 1962. Only 27 examples were manufactured. With ALCO's introduction of the Century Series line, the C-424 (specification DL-640A) replaced the RS-27 in the builder's catalog. Today, the Minnesota Commercial Railway has the only two operating RS-27s left.
