today while going through a town in kansas i saw a train with 2 bnsf engines 3 csx engines and 2 ns engines pulling a coal train with all OGEX coal hoppers
[:D]
Not always…lease power can be seen on many lines that look to be out of their natural enviroment…on “who leads” I would assume that the engine with the nicest cab would get up front duty. Just a guess there, but in KS I’d put money on BNSF as the “home road.”
All the Class I’s have power shareing agreements in place account of the various run-through operations that take place between the companies to minimize terminal delays.
Power is shared based on a ‘Horsepower Hour’ calculation that can be calculated from the Interchange Times on the equipment between the propertys. At various points in time during the year, one company may be Debiting Horsepower Hours and at another point during the year there may be a Credit balance in Horsepower Hours vs. the other carriers. At some designated point in time the Debit/Credit balance is weighed and money may actually change hands between the carriers. The carrirer on whose property the engine resides when routine maintenance is required, performs the maintenance and bills the owner.
Thanks to computers all the cross carrier accounts are handled electronically, with a specific officer in each company assigned the responsibility of monitoring the accounts and taking appropriate actions as befits the needs of his property.
In this particular case in Florida, the railroad and train was CSX, but the locomotive power was entirely BNSF a C44-9W, SD40-2,and a patch job SD40-2 in Santa Fe paint.
