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, numbered D&RGW 555-557; renumbered 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 5571 and 5574 were 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.	Previous D&RGW rosters have shown that D&RGW 5561 was wrecked on 19 December 1963 at Mill Fork, Utah, then repaired and returned to service. Three photos of the wreck scene recently uncovered by Steve Seguine of Orem, Utah, shows that two ABBA sets of units were involved, with 5661 and 5701 being the wrecked units after colliding head-on. D&RGW 5561 was not involved.
g.	D&RGW 5571 (along with F3A 5531) was wrecked on 20 November 1953 at Dos, Colo.; the unit received a complete F9A carbody as a result of wreck repairs by EMD in February 1954 under EMD order number 8032; both units were completed with the new gold, silver, and four-black-stripe paint scheme, although 5571 had already been repainted to the new scheme following wreck repairs to 5574 in 1953; later, D&RGW 5571 was one of the last F units in service with the four-stripe paint scheme, repainted to the single stripe scheme in October 1968.
h.	Built under EMD order number E-956 (shared with F7Bs 5552-5573).
