HOW MUCH BNSF LOCOMOTIVES ARE THEY GETTING RID OF TO MAKE ROOM FOR "GREEN" LOCOMOTIVES, WILL ALL OF BNSF'S OLDER LOCOMOTIVES BE GETTIN RID OF?
Gotten rid of?
More likely not. Well, not for a while, yet. It all depends on when the units reach the end of their service lives and the economics of operating them (such as fuel consumption, obtaining spare parts, etc.) gets to be more than the cost of buying new equipment.
And I don't know how many are up for retirement. Anybody eles in the class have the answer to that?
