I have seen this before where 3 locomotives were doing it at the same time. Still happens from time to time on a single locomotive but you won't see it as often http://www.liveleak.com/view?i=3e4_1327483866

I came across some videos of the Nagoya Railroad back in the late 70's. http://www.youtube.com/watch?v=9fL0QYcYT5U&feature=channel_video_title http://www.youtube.com/watch?v=McrjDWDuldY http://www.youtube.com/watch?v=r7o_irD9IoM Even back then the trains used musical horns. I have to wonder if any of these are preserved. Zeether fucked around with this message at 05:02 on Jan 27, 2012 |

We have guidelines for running ECP trains. The only ECP trains we have are rare unit trains of all the same kind of car. I haven't seen one for a couple years now. I have seen even less of the ECP retrofit boxes on top of any of the control stands in a while either.

I think its ZLANO or something along those lines. Its just a stacker, I think there is like 6 train sets or so. I think its like 12 or so 7000's that have the control stands on them. Ok, I just got back into the chair after a 3 year absence and is it just me or the newer SD70ACe's don't grip the rail worth a poo poo?

On our mountainous district we only hate the ride, not the power they provide. Under heavy heavy loads and configured in DP they are just fine crawling up the hill for 4 hours at 14mph.

How do the traction motors/engine not overheat like crazy when pulling such heavy loads at low speed?

The fans on top are for the engine radiators and dynamic brakes, aren't they? I thought the traction motor cooling fans were just gigantic squirrel cages mounted right on the bogie, presumably blasting out the bottom or side or something.

I never heard the full story so the only thing I can assume is a switch was either not lined or switched from power to hand and never thrown back. "Restricted speed" is a rule written in blood. It is moving your train at a speed not to exceed 20 MPH but as slow as you need to go to be able to stop quickly to avoid switches lined the wrong way, derail devices, red flags, men, equipment, landslides, the rear end of other trains, even missing bridges, missing track, broken rail, a train or lading wrecked from one track over and onto your track. If it as at night, foggy, a curve with terrain or anything else blocking your view, restricted speed could be less than 1 mph. If there is any question as to your ability to stop, then you may have the conductor walk ahead to ensure the way is clear and then bring you ahead, even if it is miles. Failures to adhere to this rule resulted in these 5 incidents. Two of the incidents resulted in in the two man crew being killed (4 fatalities). At least one of the other incidents resulted in injuries and one of the incidents had no injuries. The FRA has done a review and has required that additional training and testing on restricted speed will continue to be done. Failure of even one of these tests can result in being pulled from service/suspension of licenses. A simple lapse of judgement, situational awareness, or distraction while moving a train at restricted speed can end your life or the lives of others. At any given moment day or night, there are probably 100 trains moving at restricted speed. Many/most of these trains are hauling hazardous materials in populated areas.

It is basically a 300-400 horsepower electric motor connected to what is basically the compressor fan from a jet engine. When modulating the dynamic brake effort it sounds like someone modulating the throttle on a jet engine. I understand the restricted speeds, as with TERMSD, and stopping in half the range of vision, I've put a few slow orders out there and ran trains through my B's at restricted speeds. I just never heard the whole story, we don't hear much about the transportation side of things.

Do Locomotives have to rev up the engine when the notch up in dynamic braking? Like if you went from notch 8 forward to dynamic, would you have to notch to 0, then hit the dynamic braking lever, and then back to 8?

ijustam posted:Do Locomotives have to rev up the engine when the notch up in dynamic braking? Like if you went from notch 8 forward to dynamic, would you have to notch to 0, then hit the dynamic braking lever, and then back to 8? Don't quote me, but the notches for DB are a little different. Traction motors effectively turn (when powering) electrical energy into kinetic, they work backwards in dynamic brake, basically becoming giant generators. Unfortunately most (if not all) of the electrical energy is just dumped across resistors, resulting in gigantic amounts of heat, so unless the engine needs to spool up to run the cooling for the DB grid, I don't see why the engine would necessarily need to run up. Makes sense though that they'd use the energy generated from the dynamic brake to run the DB cooling fans though. So in short, no, I don't believe the engine needs to spool up when in dynamic brake.

Because men and equipment on the other track, run them through at 40mph on tangent and 25 on curve. Its in the MWOR. Men have to be off equipment and off the track to run at max, and that kills production when your clearing 30 trains a day.

Traction motors effectively turn (when powering) electrical energy into kinetic, they work backwards in dynamic brake, basically becoming giant generators. The engine will actually rev up as you increase DB effort. The main alternator is used to excite the fields in the traction motors, so with more excitation you get more braking effort out of the motors. That's how I understand it at least, I'm more mechanic than electrician.

Canna Happy posted:Ah yeah, I thought you were talking about 6.27 6.27 has become a huge issue on our service unit... But yet again, we are pretty much in the shitter in terms of de-certs and "human" factor derailments. So we get to shove all long draw bars to a joint, then the next car on top of that long draw bar has to be made to a joint. We are a flat switching yard with a kick rear end bowl (seriously some awesome engineering went into this yard). Normally kicking cars, we could easily switch out around 400 cars a shift. Now we are lucky to break 200... talk about boring as gently caress.
