Six axle comfort cabs on shortlines: Comfort cabs took North America by storm in the late 1980s with the introduction of the design on EMDs’ SD60M and GE’s C40-8W. While Canadian operators had been using the design since the early 1970s on both four and six-axle locomotives, it wasn’t until the SD60M and C40-8W arrived that the new standard for six-axle cab design would sweep the industry like wildfire for decades to come.

Over the years, a number of smaller railroads would order six-axle comfort cab locomotives new such as Iowa Interstate, Montana Rail Link, Ontario Northland, Cartier and Quebec North Shore & Labrador, but the second-hand market saw relatively few of these due to the Class One railroads still holding onto the majority of their purchases. The Class I trend of AC traction, distributed power and Precision Scheduled Railroading in the past several decades have made many of these original comfort cab fleets expendable and have been trickling down to the second-hand market with more frequency. Gone are the days where regionals and short lines were exclusively standard cab domains, with more and more acquiring larger six-axle power, many of which have the comfort cab design.

  1. James Croft, I too have often wondered about this so here’s a brief description that I found from regarding Santa Fe’s upgrade to comfort cabs.
    “Enter the comfort cab with its spacious state-of-the-art, desk top control console, redesigned instruments and brake and throttle levers, wide windshield and even a spongy floor covering that is easier on the feet. A digital speedometer dominates the panel. Naturally, there is baseboard electric heating, as well as air conditioning that evenly distributes temperatures…”

    For more info just search for “what is a comfort cab on a train locomotive”. There are some pretty good descriptions.

  2. Not sure how you classify the Alaska Rail Road but they currently roster 28 – SD70MAC’s.

  3. I may be the only one out here who doesn’t understand the significance of the term “comfort cab.” In my mind, it evokes images of plush seats and springs to make the crew’s work space more comfortable. Could you elaborate for people like me?

  4. One correction to the list:. New York, Susquehanna and Western currently has ex-NS SD70M-2s. They had 3 SD70Ms that they got in the late 80s/early 90s, but sold them to NS around 2012, when NS brought them to alleviate a motive power shortage.

  5. Another driving force here is PTC. Many of the older locomotives would take an extreme amount of money to retrofit to PTC. Shortlines can get already equipped units from Class 1 RRs or leasing companies way easier. A lot of the older power’s age is beyond usefullness. In some locations, corrosion is also a major factor and locos are well past structural standards.

  6. This a great list I knew there were some, but had NO idea so many “little” roads had them. Good job by “Trains”.
