Southern Pacific Railroad - Locomotive Paint and Appearance

Locomotive Paint and Appearance

Like most railroads, the SP painted most of its steam locomotives black during the 20th century, but after 1945 SP painted the front of the locomotive's smokebox silver (almost white in appearance), with graphite colored sides, for visibility.

As locomotives are being restored, some Pacific type 4-6-2 locomotive boilers show 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. Some other SP steam passenger locomotives may have been so painted, or at least had dark green boilers. The article indicates that these paint jobs lasted years and were not special paint for a single event.

Some 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 on the tender, was a bright red on the top and bottom thirds, with the center third being a bright orange. The parts were separated with narrow 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 2-8-8-4 locomotives set up to run in reverse, with the tender attached to the smokebox end of the locomotive. Southern Pacific had a number of snow sheds in mountain terrain, and locomotive crews nearly asphyxiated from smoke in 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.

Early diesel locomotives were also painted black. Yard switchers had diagonal orange stripes on the ends for visibility, earning this scheme the nickname of Tiger Stripe. Road freight units were black with a red band at the bottom of the car body and a silver and orange "winged" nose. "SOUTHERN PACIFIC" was in a large serif font in white. Railfans call this paint scheme Black Widow. An experimental scheme, all-over black with orange "winged" nose, was called the Halloween scheme. Few engines were so painted 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 the Golden State (operated with the Chicago, Rock Island and Pacific Railroad) between Chicago and Los Angeles. 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; railfans dubbed this scheme Bloody Nose. Lettering was again in white. Anticipating 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 recognizable.

Southern Pacific road switcher diesels often had elaborate lighting clusters front and rear, with a large red Mars Light for emergency signaling, and often two pairs of sealed-beam headlamps, one on top of the cab and the other below the Mars Light on the nose. Starting in the 1970s SP had cab air conditioning on all new locomotives and the unit is visible on the cab roof. Southern Pacific placed large snowplows on the pilots of their road switchers for the heavy snowfall on Donner Pass. Many Southern Pacific road switchers had a Nathan-AirChime model M3 or M5 air horn with chords distinct to Southern Pacific locomotives in the western states.

The Southern Pacific and Cotton Belt were the only buyers 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 through snow sheds and tunnels in the Cascades and Donner Pass. These "Tunnel Motors" were EMD SD45-2's with radiator air intakes at the locomotive car body's walkway level, rather than EMD's typical setup with fans on the locomotive's long hood roof pulling air through radiators at the top/side of the locomotive's body. Inside tunnels and snow sheds hot exhaust 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.

Southern Pacific was known for 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 nose" 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.

Unlike other railroads whose locomotive number boards bore the locomotive number, SP used them for the train number until 1967. (SP's San Francisco-San Jose commute trains continued displaying train numbers for the convenience of passengers.) The other railroad that used locomotive number boards for train numbers into the 1960s was SP's transcontinental partner, Union Pacific.

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.Today there are still locomotives in SP paint,including Ten AC4400CWS with original SP numbers as of January 2013.
