General Notes:

a.	UP 410 was equipped with Dynavane primary and Roto-namic engine air filters, replacing the original carbody and secondary oil bath engine air filters.
b.	UP 414 was modified with an upgraded electrical cabinet, AR10 alternator, and 645 power assemblies in May 1974, as a prototype for a rebuild program for UP's large fleet of SD24s, to improve reliability and bring them up to current SD40-2 standards. Some internal UP documents refer to the unit as an SD24-4. SD24M 3100 (ex UP 423) in 1968 was also part of this search for rebuilding technologies for the 79-unit SD24 fleet.
c.	UP 423 was rebuilt to SD24M 3100 in August 1968. The rebuild included a constant speed EMD 16-645 3000 horsepower engine (with speed control taking place by changing the level of excitation of the main generator) and traction motors permanently connected in parallel. UP tried many other features, including a variable dynamic braking feature, first used on the small 51-75 single unit turbines. UP 3100 was also the first unit on UP to have the capability of a self-load test, rather than being connected to an external load box. This self load feature was first delivered on UP's DDA40Xs, and on almost all production units from EMD after 1971.
d.	Beginning in the early and mid 1970s, UP SD24s worked as heavy yard switchers. UP 414 and 419 were long-time residents of Ogden, Utah, yard. In early 1979, UP's remaining 21 SD24 A-units were all reassigned from secondary road service to yard service, with most being assigned to the huge twin hump yards at North Platte, Neb., replacing the ailing 2800-class GE U28Cs.
e.	UP 407, 416, 418, 421, and 427 were sold to Precision National Corp. and rebuilt to 1800 horsepower, non-turbocharged. Used in Precision's national lease fleet until sale to C&NW in March 1982. Renumbered to C&NW 6600 class. Returned to UP in the UP/C&NW merger, assigned new UP numbers 2896-2899 (none renumbered prior to retirement by UP).
f.	Built on EMD order number 5602.
