I was watching a couple of NS gp38s moving some grain around the yard and they had to double the train because of the weight. How would a Yardmaster of Trainmaster determine yard power.
Doubling means to cut a train in half and take one section over a mountain grade and return to get the other section and bring it over the summit.
Doubling a train in a yard due to weight? You might have seen normal switching in action.
Yard power is not important. Road power is and will always recieve careful consideration.
I thought i have heard the term doubling to pull a train out of a yard. I could be wrong though. Anyway it seemed they didnt have enough power to pull the entire train.
Roight. I forgot. So sorry.
During RCO training we blew up or SD 40 here in Galesburg ( it was a shop queen anyway) so they gave us the GP 38 and promised we would only pull "small"trains out of the bowl. HA HA 16,000 tons later we are screaming along at 3 mph heading out to pull past the departure yard to shove back in.Was in full power all the way and watched the ammeter peg all the way out.When stopping all I had to do was shut her down slow to the standby mode where the engine brakes start setting up. Needless to say we tied up the yard for over an hour.
Most of our yard pull out jobs are like I said SD-40's. Hump sets are 3 SD-40''s. Our little GP 38? after that movement the powers that be decided to MU another GP 38 to her so now shes a double unit.
Yes we are on time but this is yesterdays train
When I'm back in my hometown of McCook,NE, I like to go down to the yard to see whats happening.For they switch engine, they now use two GP38-2's where they used to use one SD9. How's that for progress! I wonder if the crews would rather have the SD9's back?
doubling tracks also means taking one track of cars and coupling them up to another cut of cars.. to build one longer cut... road trains where will take a track for a pickup and double it to another track for an outbound train..or double it back to there inbound train and take off... doubling also dose pretain to making a hill if you dont have enought power to make it in one cut and no helper service to give you a shove...

Yard power is whatever I can beg, borrow, or steal.

In Northtown, they use two SD40-2s (BNSF 6332 and the 7821) as the pull out jobs. They have the 7039 and the 8030 (SD40-2s) as Pullout/Hump power. We have two sets of Hump Power also, SD39s with Slugs.
