The motors are "Spring Nose" suspended and have a gear ratio of 4.25. (I assume "GE" stands for General Electric.) It also has four " Traction Motors" of type "GE 287E".Īn original data card dated June 1931 ( image) lists a "600 H. It also has a "Main Generator" of type "GE - GT551A1". A data sheet for the Alco HH-600 states that it has an 4-cycle Model 538 6L built by Alco. This would be an important fact and should be highlighted in the article. If they are truly diesel-electric, then their early introduction in 1931 would make them some of the earliest diesel electric systems. The article does not mention the type of transmition, are the locomotives diesel-mechanical or diesel-electric? 22, 2005 Diesel-mechanical or diesel-electric? 1938, so they should be moved from the HH600 to the HH660 list.

The October 1938 build date for GBW 101 is consistent with HH600 production, which went from July 1932 through May 1939. The evidence points to GBW 101 was built as an HH600 - see the reference to Alco's roster listing it as an HH600 and GBW's equipment diagram showing it as 600 HP (both noted above). Having a 538 engine could also be an HH600. 28, 2005 The HH600 section of this Wikipedia article says that "late versions of this locomotive used the 6-cylinder 538 engine," so having a model 538 engine does not necessarily mean that the locomotive is 660 HP, and thus an HH660. The initial 600HP designation should make it an HH600.
ALCO HH660 RAILWORKS DOWNLOAD SERIAL NUMBER
According to a nationwide roster which Alco itself kept revised to 12/67 GBW #101 contained a 600-HP 538 engine, serial number 2513. SSW9389 00:27, 27 November 2005 (UTC) The production date (1938) is not in question. Production date from X2235 Alco HH roster. GB&W #101 was built in October 1938, its an HH660.

"The last Model 531 equipped 600 horsepower switcher was delivered in June 1938 and the first Model 538 660 horsepower unit was produced in August 1938." from Steinbrenner p. I got the '539' part from one of the referenced books, but there's a good chance they were wrong. Alco also lowered the 539 engine in the frame to lower the overall hood height.
ALCO HH660 RAILWORKS DOWNLOAD GENERATOR
That is why the radiators are at the far end of the carbody, and the generator is close to the cab on the S-1/S-2 model Alco switchers. The 539 took the 538 and reversed it in the carbody. See also the note in DSG2 on page ALCO-208, "There appears to have been a variation 8/38 to 7/40 on the 531 engine called the '538'." This is the engine used in the High Hood 660s and 1000s, not the 539. Diesel data from A Centennial Remembrance by Richard Steinbrenner see Alco's first production diesels pp. Alfred Buchi of Switzerland in 1936-1937. The HH900 used the 531T engine as developed with the assistance of Dr. The HH660 used the 538 engine and the HH1000 used the 538T diesel engine. The 539 engine started use with the S-1 and S-2 locomotives.

No High Hood Alco switchers used the 539 engine. Morven 07:07, (UTC)Įngine data on the HH660 and HH1000 line of locomotives is inaccurate. It's possible that they fitted a M&S 539 engine to replace the original, making it effectively a HH660, but we should see if we can find out anything else. In later years the GBW carried #101 as a HH660 on their official roster I have been unable to locate the date, location, and reason for the upgrade. Refer to this 1947 equipment diagram which lists it as 600 HP: The build date of 1938 is consistent with an HH600.
