I used to build those power assembies. 567 and 645 cubic inch, respectively (per cylinder X 16).
Long time ago, but I think the redline on the engines was 980RPM. All the Diesel electric powerplant does is spool up a giant alternator that provides electricity to the traction motors in the "trucks". Every wheel on a locomotive has a motor driving it. To slow down the locomotive, the whole roof of the unit is filled with resistor banks that the engineer can choose from to load up the motors and cause magnetic drag. Funny thing is that today's hybrids are using the same basic technology to save fuel. GM Electromotive owns the design and patents, and has been using and collecting from them since the 50's. Sorry for the thread drift, pics are cool and NO, a human being does not want to be anywhere close to one of those suckers on a runaway. The shrapnel hits before the shockwave. |

A long time ago in another life my employer, General Electric, sold me to another GE shop when our shop ran out of work. I was sold for a couple of weeks to the GE locomotive shop in Minneapolis.

I spent the whole time suited up in hot protective gear rebuilding locomotive resistor grids. Just like this - a continuous steel band encased in a hard asbestos frame:   The grid frames were made of asbestos because the steel band making the resistive element would get red hot. The resistor grid was frequently like a big red hot electric grill. Sometimes they would get so hot that the steel ribbon would melt in two. So, all day every day I was taking apart the asbestos frames, cutting out the melted sections with an air tool and cutting wheel, and then using scraps of cut up resistor band to piece together a complete resistor band for the shop welders to stitch back together again. After I got my rewelded ribbon bands back I would reassemble them in new asbestos frames. At the end of the day I was covered in asbestos dust, rust, and metal grit from all the cutting. Braking resistors are used in a lot of heavy machinery.     |

I was on a loaded soda ash train coming home from Green River when the engineer looked out his back window and said "holy shit we're on fire"
. The third loco in our consist which was a GE AC4400 identical to the one in the OP threw a piston through the engine block and pretty much destroyed the engine and leaked gallons of oil everywhere and made a pretty good fireball too.

One of the risks of built up engines.
but I think the redline on the engines was 980RPM.
Sounds way to high. the ones I have worked around could not even make 1000 RPM. They operated in the 200-300 range (but where very old ones), still DC generators. |

Sorry to correct, but they idle around230- 250rpm. We would run our rebuilds up on a load bed to 950 rpm and hold them there for 1 hour. I'm very sure the 980rpm number is stuck in my head, because if we went overy that, power assemblies would start to depart the engine block. |
