Autos East with Mid-Train Locomotives: CSX Q264 at CP79—3 Digital Photos.


In recent months CSX has adopted the practice of using distributed power on the former Boston & Albany.

Distributed power is essentially the application of radio-remote controlled locomotives positioned deep in a freight train and/or at its end to reduce drawbar stress and improve starting and braking characteristics with very long/heavy trains.

The concept dates to the 1960s, but much improved radio-controlled remote technology was introduced by GE-Harris in the 1990s where it has become standard operating practice, and the remote locomotives being known as distributed power units (DPUs)

Still, to me it seems like a novelty on the Boston & Albany route.

Yesterday (May 23, 2019), I made my first photographs of a CSX train with a DPU working east of Palmer.

Mike Gardner and I caught Q-264 (the loaded autorack train destined to East Brookfield) from the field of Route 67 near CP79.

By B&A standards, this was an enormous train for just two modern GE diesels.

I exposed these photographs using my FujiFilm XT1 with 90mm f2.0 lens.
