Yes, but both the N&W and Virginian showed the best way to use those
full-throttle turbines -- the electrification program that used overhead
power lines to run the traction motors instead of the diesel-engine-run
generator carried in each unit.  It would seem that using coal in a
stationary boiler/turbine to generate electricity would be a more efficient
way to use coal to power a railroad. Granted, there would also be high
capital costs building the support structure (catenary structure vs.
coaling/water facilities), but electric traction is already a known quantity
in the railroad world. It would be easier (ignoring for now the NIMBYs) to
manage the pollution from a fixed plant than try to mange the output from a
moving plant.

I wonder what Norfolk Southern's bottom line would look like today had it
added to the electrification in place after the VGN merger instead of
dismantling it. Would there be enough difference between the cost of diesel
fuel and coal-produced power to bump up the dividend each quarter?
