The B&O also has the distinction of being the first railroad in the country to purchase a diesel-electric passenger locomotive in 1935 from EMC (B&O #50). While these early designs were somewhat successful and new diesel switch engines were becoming quite popular from makers such as Alco, it would not be until the development of EMD’s legendary E and F models (which followed the EA/EB design they were nicknamed "covered-wagons") to pull heavy passenger and freight consists did the diesel-electric locomotive really come of age and overtake the steam locomotive as the dominant means of moving freight across America’s rails.
It would take the diesel-electric locomotive nearly fifty years to equal the horsepower output of the steam locomotive during its technological height. However, diesels
offered an advantage that far surpassed steamers and it was the
deciding factor in them becoming the prime choice of motive power,
efficiency. Diesels required far less maintenance in terms of overhauls
(scheduled time in the shops for routine maintenance) and refueling (no
longer were there frequent stops requiring water and coal/oil), which allowed them to be spending much more time moving freight and paying the bills.

Diesels have come a long way from the early designs by EMC and Alco-GE-IR, with comfort cabs and electronic equipment the norm on new units now being built by Electro-Motive Diesel (now an independent company having been spun-off by EMD in 2005) and GE. However, when the diesel was first coming of age there were still several builders, many of whom were legendary steam locomotive manufacturers (such as Baldwin, Lima, and Alco) that began switching to diesel-electric
development when the writing on the wall became apparent that steam's
days were numbered.
