General Notes:

a.	D&RGW Class DE B-B 26.
b.	An additional unit, to be numbered D&RGW 44, was diverted to the U. S. Navy.
c.	D&RGW 43 was wrecked soon after delivery; repaired by GE with later carbody design that included front radiators, replacing the as-built side radiators.
d.	Noted at the Denver Public Library web site, three photos of D&RGW 38 (44T GE) with the triple coupler pockets for coupling to either SG or NG cars. Shots show two couplers in place. Interesting is that the NG cars are coupled onto the far end of the engine demonstrating that this unit had this arrangement on both ends.

General Note:

a.	D&RGW Class DE B-B 60.
b.	D&RGW 540-547 (16 units) were fitted with couplers between the FTA units and their corresponding FTB unit, instead of the standard drawbar. EMD designated this coupler-equipped version as FS, rather than FT.
c.	Delivered as part of A-B-B-A sets, with total 5,400 horsepower, numbered D&RGW 540-551; renumbered to 5402-5513 in January to April 1950, with A-units receiving 1 and 4 as fourth digits, and B-units receiving 2 and 3 as fourth digits.
d.	D&RGW 548-551 (8 booster units) were fitted with steam generators. (The EMD 1950 Product Reference Data book shows 18 FT booster units with steam generators, D&RGW 543-551, as does The Revolutionary Diesel, EMC's FT, page 61. Photo research reveals that just these eight units actually had steam generators.)
f.	D&RGW 540-547 (16 units) had 244,000 pounds operating weight
g.	D&RGW 548 (two units) had 249,000 pounds operating weight
h.	D&RGW 549-551 (six units) had 246,500 pounds operating weight

General Note:

a.	D&RGW Class DE B-B 59.
b.	Part of a 619-unit group of transition units that have been called F5s; these are late F3s built from August 1948 to February 1949 by EMD, and many were equipped with D27B traction motors and Type B power transition control, as later used on F7s. External body features matched both late F3s and early F7s. (See Extra 2200 South, issue 96, July-August-September 1992, page 19)(Transcript of D&RGW portion here.)
c.	Delivered as part of A-B-B-A sets; renumbered to 5551-5574 in January to April 1950, with A-units receiving 1 and 4 as fourth digits, and B-units receiving 2 and 3 as fourth digits.
d.	All six cab units were fitted with built-up horizontal side grilles.
e.	D&RGW 557 was fitted with steam generators; replaced by water tanks after wreck repairs in 1954 (5571) and 1952 (5574); water tanks allowed these A-units to furnish water for the steam generators in adjacent B-units.
f.	Built under EMD order number E-956 (shared with F7Bs 555-557).
