Recently read "Lights out", about their problems in the last ~20 years, fascinating read, heartily recommended.
They sold trains and bought into oil & gas exploration. If high growth is what they're aiming for I'm not sure they picked the right horse.
Then again around here the rail lines are mostly owned by grain/grass farmer groups who ship product by rail and can load from their farm directly. Passenger lines that share the rails wait for those trains.
However, I'm not sure your conclusion about owning railroads is a nightmare is true. Berkshire Hathaway (Warren Buffet's company) bought Norfolk Southern in 2007 and it's done fairly well since. My understanding is that these are relatively stable businesses because the barrier to entry is large enough to stifle competition.
Just because it didn't retain the name "GE" doesn't mean the business is gone.
