Hi Jenny,
It may be easier to explain by giving a example of how they do things down here.
After the SP/UP meltdown, nothing, and I mean nothing moved in Houston for a few days.
Both BNSF and UP had trains jammed into every available sideing and spur they could find.
BN was stabbing every moving UP train they could, and UP was returning the favor, with a vengence.
One day, and I swear this is true, only about ten trains made it into the inner “loop” of Houston.
Almost all of the major yards, both BN and UP, are within this loop.
So they had managed to screw each other up so well, they both ended up with none of their trains moving.
Solution?
They agreed that the solution to the major part of the mess was to cooperate, they had little choice.
Together, the formed the Spring Dispatcher, known to the train crews as TD Spring, (Train dispatch Spring) to handle all of the dispatching in the major Houston/Harris county area.
Staffed by both BN and UP dispatchers, when you talk to them, if you dont know them personally, you could be speaking to a BN dispatcher, who is routing UP trains, and vice versa. They have only one mandate, to keep trains moving, regardless of whos train it is.
They handle 10 major yards, and several smaller yards, along with all the main line into and out of Houston.
It works, better than you would have guessed.
No longer do you have to wait while this division super talks to their division super to run a BN over UP, or vice versa.
The dispatchers are all housed in the same building, working on the same system side by side with each other.
If the need arises for one railroad to use the tracks of the other, they dont even have to phone each other, they just do it.
Jump to the UPS train on BN tracks.
If BN stabbs this train, UPS will howl.
Shippers will complain.
BNSF and UP know they are the only two major players this side of the mi
