Beginning during the late winter and early spring of 1925 various components started coming together at the General Electric Erie Works for construction of the first production Diesel-electric locomotive...  AGEIR Demonstrator #9681 built under ALCO Order # S1484 (ALCO Builders #65979 & GE Builders #9681) ...

Dr.Hermann Lemp began employment with General Electric in 1892 and in 1910 accepted the assignment of developing a control system for internal combustion-electric locomotives.  The above controls reflect the "state of the art" for this system as of 1922.  During 1925 Dr. Lemp left GE and went to work for Ingersoll-Rand and in 1926 General Electric and Dr. Lemp were granted a patent on this generator/excitation system.  It wasn't until 1929 that this methodology evolved to its optimum efficiency when Dr. Lemp came to realize that the key was with differential field windings while he was riding aboard New York Central designed ALCO - AGEIR-built prototype locomotive #1550 (ALCO Order # S1533, ALCO Builders #66704, GE Builders #10088 {below}, and employing the Ingersoll-Rand 750 horsepower Diesel plant which was marketed but not utilized in the AGEIR Oil-electric locomotives.  Ordered December 28, 1925 and completed June 12, 1928).  This perfection of the control system continued to be used in the production of Diesel locomotives for many decades...
