Mack Locomotive

  • Hi can anyone give me some info on engines like these:

    They are Mack switchers but I would like to know more about them. How much did they weight, etc.

    Hi can anyone give me some info on engines like these:

    Don't know too much about a specific Railroad switcher, but the 'noses are definitely copies of the old AC Mack Truck. dating from the early 1900's and used pretty extensively in WW1. Not to mention they played a major roll in the Army's First attempt at a Transcontinental Truck Trip of 1919. This was an exploratory mission to see if it would be possible to drive from Washington,D.C. to the West Coast.  

      It was ordered by then Gen of the Army John " BlackJack Pershing, and then Cavelry Lt. Dwight D. Eishenhower went along in the role of observer. Many feel it was this trip that caused Gen Eisenhower to push the plan in the 1957 for the Interstate and Defense Highway Network across the U.S.

    If you go to this link you can seee photos of the distinctive Mack AC hoods:

    The famous AC model was introduced in 1916. With its chain drive rear axle, the AC model earned an unparalleled reputation for reliability and durability, and was called on to help accomplish nearly impossible military and civilian tasks. The AC model was manufactured continuously through 1939 -- a remarkable 24 years, and 40,299 were built. The AC is not only credited with giving Mack its famous Bulldog identity, but also with achieving a degree of success and international fame that has never been accomplished by any other motor truck in history.

    Mack built a military armored car on an AB Chassis for the New York National Guard. During World War I, Mack delivered approximately 4,500 AC model trucks of 3-1/2, 5-1/2, and 7-1/2 ton capacity to the US government. During that same period, Mack delivered over 2,000 units to Great Britain. These trucks did an outstanding job under very difficult conditions.

    The story goes that the British soldiers ("Tommies") would call out when facing a difficult truck problem, "Aye, send in the Mack Bulldogs!" The primary, and generally universal, story is that the British engineers testing AC's and the Tommys in France said that "the Mack AC's have the tenacity of a bulldog." At that time, the symbol of Great Britain was the bulldog, and this was high praise for the trucks. American "Doughboys" expressed the same opinion of the truck.

    A new holding company, the International Motor Truck Corporation, is formed; it assumes the notes payable obligations of the International Motor Company and owns 98 percent of its stock. The International Motor Company, through its ownership of the Mack Brothers Motor Car Company, the Saurer Motor Company, and the Hewitt Motor Company, becomes the operating organization, with its main plants in Allentown, PA (Mack), Plainfield, NJ (Saurer), and Brooklyn, NY (Hewitt).

    The International Motor Company also owns the International Mack Motor Corporation, which had been set up in December 1915 to run most of the company-owned branches. However, by the end of World War I, the title of this company is changed to the Mack-International Motor Truck Corporation.

    The Saurer nameplate is discontinued in the United States.

    Mack became the first truck manufacturer to apply air cleaners

    Dug a little deeper and forund this link to some actual MACK Locomotives:

    Actually pretty interesting about the WK&S RR ( In Penna) that had Mack Locomotives, unfortunately, I think the adaptation of the  Mack AC hood was a toy designer's wishful thinkingMischief

    Hope this will help you!


    ( Sorry could not pull the photos to this site.)





  •  Look at the locomotive pictured on this website;

    Mack Truck Locomotives


    Fourth row down, third picture to the right, click onit to enlarge.

  • There has been one sitting along the Black River and Western RR in Ringoes, NJ for years but I have never seen any indication that it runs.

  • I wonder if there is any video anywhere showing them running.

  • They appear to be garden railway locomotives, so I would guess about 2#.  Mack Truck had a dismal record building railway equipment.  New York Central bought the gas car #M-14 for use on the Putnam Division in 1928.  It was way under-powered and was sold to the Washington & Old Dominion (their #45).  Mack also built a bunch of "Rail Buses" for the New Haven.  They, too, didn't work out.  I think only two were ever used in revenue service.  Another case, like Boeing, of a company that should have stuck with its expertise.  Being, now, a French-owned company, I would hate to see any of my tax dollars go to future Mack efforts.


  • You are correct about those being GR loco's. They are in 1:24 scale. (I'm a Garden Railroader)

  • Thanks, Beaulieu!

                                 Got in a hurry and missed looking at N.E. Rails website they are a thorough reference area. The WK&S was one I remembered from some time back. 

      I guess it goes to show that life often replicates itself even where locomotives are concerned. The Garden Rails engines pictured in the original post are pretty much true to the prototypes pictured in the NE Rails website. 

      The AC MACK was one tough truck and  wonder how much of it was actually used to create the loco pictured?





  • The WK&S website - ''Projects'' page - says [note - date not specified]:

    What's Gone from the WK&S..

    The Mack was sold to JC McHugh and has been refurbished and is awaiting motive repairs at their facility.

  • In New York City, "Colonial Sand & Stone" used lots of Mack 'AC's, even into the 1970s, on their transit-mix, sand, cinder, and aggregate trucks, supplying the building industry.  The dwindiling coal delivery companies did, too.  IIRC, they were all chain-drive.  Cool old rigs -- some of them still had solid rubber tires!  Not much operator comfort or weather protection.  What drive-train did the Mack locomotives use?  Chain?


  • They remind me of a picture I had as my desktop background. The caption was "1931 Mack Truck company 15T gas-el." Can't find the pic, but think I got it from Trains Mag newsletter, possibly Photo of the Month.
