The M420 was equipped with the ALCO 12V-251c3 prime mover producing 2000 H.P. Most M420 quired a different bolster design and a slightly different truck spacing, making them unique.
MLW constructed 103 M420s between May 1973 and February 1977 for four railways including CN (80), BCR (16 including eight B units), Ferrocarriles del Estado (2), Providence & Worcester (5
CN would take delivery of the M420s in 3 groups: MR-20a class 2500-2529 (delivered 1973), MR-20b class 2530- 2559 (delivered 1974), and MR-20c class 2560-2579 (delivered 1976). All of the CN units were retired by 1998 and today many of these locomotives have found second careers on short lines all over North America.
