Funny to see the engineer looking out the window to see if he's moving yet.

Any good hoghead will look out that window when starting that much tonnage. Great video!

It sure isn't going to set a drag strip record on the quarter mile but a dragster isn't going to budge that thing. That's one impressive display of power. That's also some nice work in recording it, both picture and sound.

Just wondering.. Are those AC traction units, if so, would DC traction have been able to handle that? Edited 1 time(s). Last edit at 10/15/14 18:01 by steve_misky. Date: 10/15/14 18:13 Re: What it takes to get 18,000 tons going - on a 2.2%g Author: SlipperyWhenWet he isnt looking out the window to see if he is moving, he obviously knows he hasnt yet. He is looking to make sure he doesnt have wheel slip, you can really f*ck up an engine if you have wheel slip and keep it notched up.
Yes those would be AC traction engines and no DC would not be better, AC traction is 100x better than DC traction. It takes 3 DC engines to do the same work that 2 AC engines do. AC engines you cant burn out the traction motors, DC go out pretty easily when you are working with real heavy trains. Those AC traction motors are best used for low and slow speed with extreme heavy tonnage Date: 10/15/14 18:33 Re: What it takes to get 18,000 tons going - on a 2.2%g Author: steve_misky thanks. I was also thinking the engineer was making sure he wasn't moving backwards..
I assume, he's trying to hold the train under power while the head-end releases the brakes and then stretches the head end of the train, since the helpers seemed to "suddenly start moving" when they started to move.?

Date: 10/15/14 19:47 Re: What it takes to get 18,000 tons going - on a 2.2%g Author: fbe One way to do this is to listen for the engineer to say, "Helpers, here we go." The helper engineer moves the reverser to foreward, backs the independendent brakes back to say 40 psi and moves the throttle to 3 or so to get about 1,000 amps on the traction motors. As the brake pipe pressure starts to come up, add more throttle and drop the independent brakes. As the helpers start to move it is full mu sand and as much power as you can add without slipping. You get to run 8 pretty quickly and just stay there unless the engineer asks you to back off.
Others may do things differently but this is a common method. |
