Southern Pacific Transportation Company - Locomotive Paint and Appearance

Locomotive Paint and Appearance

Like most railroads, the SP painted the majority of its steam locomotive fleet black during the 20th century, but after the 1930s the SP had a policy of painting the front of the locomotive's smokebox light silver (almost white in appearance), with graphite colored sides, for visibility.

As locomotives are being restored, some Pacific type 4-6-2 locomotive boilers are showing signs of having been painted dark green. The soft cover book "Steam Glory 2" by Kalmbach Publications (2007) has an article "Southern Pacific's Painted Ladies" which shows color photos from the 1940s and 1950s revealing that a number of SP 0-6-0 yard engines, usually assigned to passenger terminals were painted in various combinations with red cab roof and cab doors, pale silver smokeboxes and smokebox fronts, dark green boilers, multi colored SP heralds on black cab, green cylinder covers and other details pointed out in color. It is possible that some of the other SP steam passenger locomotives were also painted in these colors or at least had dark green boilers. The article indicates that these paint jobs lasted quite a while and were not special paint for a single event.

Some express passenger steam locomotives bore the Daylight scheme, named after the trains they hauled, most of which had the word Daylight in the train name. This scheme, carried in full on the tender, consisted of a bright, almost vermilion red on the top and bottom thirds, with the center third being a bright orange. The parts were separated with thin white bands. Some of the color continued along the locomotive. The most famous "Daylight" locomotives were the GS-4 steam locomotives. The most famous Daylight-hauled trains were the Coast Daylight and the Sunset Limited.

Well known were the Southern Pacific's unique "cab-forward" steam locomotives. These were essentially 2-8-8-4 locomotives set up to run in reverse, with the tender attached to the smokebox end of the locomotive. Southern Pacific used a number of snow sheds in mountain terrain, and locomotive crews nearly asphyxiated from smoke blowing back to the cab. After a number of engineers began running their engines in reverse (pushing the tender), Southern Pacific asked Baldwin Locomotive Works to produce cab-forward designs. No other North American railroad ordered cab-forward locomotives, which became a distinctive symbol of the Southern Pacific.

During the early days of diesel locomotive use, they were also painted black. Yard switchers had diagonal orange stripes painted on the ends for visibility, earning this scheme the nickname of Tiger Stripe. Road freight units were generally painted in a black scheme with a red band at the bottom of the car body and a silver and orange "winged" nose. The words "SOUTHERN PACIFIC" were borne in a large serif font in white. This paint scheme is called the Black Widow scheme by railfans. A transitory scheme, of all-over black with orange "winged" nose, was called the Halloween scheme. Few locomotives were painted in this scheme and few photos of it exist.

Most passenger units were painted originally in the Daylight scheme as described above, though some were painted red on top, silver below for use on the Golden State (operated in cooperation with the Chicago, Rock Island and Pacific Railroad) between Chicago and Los Angeles. Also, silver cars with a narrow red band at the top were used for the Sunset Limited and other trains into Texas. In 1959 SP standardized on a paint scheme of dark grey ("Lark Gray") with a red "winged" nose; this scheme was dubbed Bloody Nose by railfans. Lettering was again in white. During the failed Southern Pacific Santa Fe Railroad merger in the mid 1980s, the "Kodachrome" paint scheme (named for the colors of the Kodak boxes that the film came in) was applied to many Southern Pacific locomotives. When the Southern Pacific Santa Fe merger was denied by the Interstate Commerce Commission, the Kodachrome units were not immediately repainted, some even lasting up to the Southern Pacific's end as an independent company. The Interstate Commerce Commission's decision left Southern Pacific in a decrepit state, the locomotives were not repainted immediately, although some were repainted into the Bloody Nose scheme as they were overhauled after months to years of deferred maintenance. After the 1988 purchase of Southern Pacific by Denver and Rio Grande Western Railroad owner Philip Anschutz, the side lettering on repainted locomotives was changed from SP's serif font to the Rio Grande's "speed lettering" style. The Rio Grande did not retain its identity, as Anschutz felt the Southern Pacific name was the more dominant and recognizable.

Southern Pacific road switcher diesels were well known by railfans for several distinct features beyond their paint schemes. The units often featured elaborate lighting clusters, both front and rear, which featured a large red Mars Light for emergency signaling, and often two sets of twin sealed-beam headlamps, one on top of the cab between the number boards, and the other below the Mars Light on the locomotive's nose. The Southern Pacific, starting in the 1970s, employed cab air conditioning on all new locomotives, and the air conditioning unit on top of the locomotive cab is quite visible. Southern Pacific also placed very large snowplows on the pilots of their road switchers, primarily for the heavy winter snowfall encountered on the Donner Pass route. Many Southern Pacific road switchers used a Nathan-AirChime model M3 or M5 air horn, which formed chords which were distinct to Southern Pacific locomotives in the western states.

The Southern Pacific, and its subsidiary Cotton Belt, were the only operators of the EMD SD45T-2 "Tunnel Motor" locomotive. This locomotive was necessary because the standard configuration EMD SD45 could not get a sufficient amount of cool air into the diesel locomotive's radiator while working Southern Pacific's extensive snow shed and tunnel system in the Cascades and Donner Pass. These "Tunnel Motors" were essentially EMD SD45-2's with radiator air intakes located at the locomotive car body's walkway level, rather than EMD's typical radiator setup with fans on the locomotive's long hood roof pulling air through radiators mounted at the top/side of the locomotive's body. Inside tunnels and snow sheds, the hot exhaust gases from lead units would accumulate near the top of the tunnel or snow shed, and be drawn into the radiators of trailing EMD (non-tunnel motor) locomotives, leading these locomotives to shut down as their diesel prime mover overheated. The Southern Pacific also operated EMD SD40T-2s, as did the Denver and Rio Grande Western Railroad.

The Southern Pacific was also notable for ordering L-shaped engineer's windshields. Introduced by EMD on SD45 demonstrator 4353, this design improves visibility by omitting the pillar which in conventional designs splits the engineer's windshield into two panes. Southern Pacific selected this option on new EMD locomotive orders starting in 1967 through the early 1980s, one of the few railroads to do so (Illinois Central was another buyer of this option), and ordered a similar windshield design from General Electric. After the "wide cab" design became popular, most of Southern Pacific's locomotives kept their L-shaped windshields before being rebuilt or sold to different private railroads after its merger. Many railfans consider it odd but at the same time distinctive since Southern Pacific was one of the few railroads to order this option.

Unlike many other railroads, whose locomotive number boards bore the locomotive's number, SP used them for the train number until 1967, when they adopted the other railroads' "standard," except for the SP's San Francisco-San Jose commute trains, which maintained the display of train numbers for the convenience of passengers awaiting their trains. The other major railroad which used locomotive number boards for train numbers into the late 1960s was SP's transcontinental partner, Union Pacific.

Toward the end of the railroad's corporate life, Southern Pacific locomotives were known for being very dirty. Some railfans jokingly observed that the railroad's heavily used locomotives were only washed when it rained.

Union Pacific recently unveiled UP 1996, the sixth and final of its Heritage Series EMD SD70ACe locomotives. Its paint scheme appears to be based on the Daylight and Black Widow schemes.
