Greater Los Angeles is the second-largest metropolitan area in the United States (after New York), with a population of 18.5 million in 2021, encompassing five counties in Southern California extending from Ventura County in the west to San Bernardino County and Riverside County in the east, with Los Angeles County in the center and Orange County to the southeast. According to the U.S. Census Bureau, the Los Angeles–Anaheim–Riverside combined statistical area covers 33,954 square miles (87,940 km2), making it the largest metropolitan region in the United States by land area. Of this, the contiguous urban area is 2,281 square miles (5,910 km2), the remainder mostly consisting of mountain and desert areas. In addition to being the nexus of the global entertainment industry (films, television, and recorded music), Greater Los Angeles is also an important center of international trade, education, media, business, tourism, technology, and sports. It is the 3rd largest metropolitan area by nominal GDP in the world with an economy exceeding $1 trillion in output (behind Tokyo and New York City). There are three contiguous component metropolitan areas in Greater Los Angeles: the Inland Empire, which can be broadly defined as Riverside and San Bernardino counties; the Ventura/Oxnard metropolitan area (or Ventura County); and the Los Angeles metropolitan area (also known as Metropolitan Los Angeles or Metro LA) consisting of Los Angeles and Orange counties only. The Census Bureau designates the latter as the Los Angeles–Long Beach–Anaheim metropolitan statistical area, the fifth largest metropolitan area in the western hemisphere and the second-largest metropolitan area in the United States, by population. It has a total area of 4,850 square miles (12,561 km2). San Diego–Tijuana, though contiguous with Greater Los Angeles at San Clemente and Temecula, is not part of it, but together both form part of the Southern California Megalopolis. Throughout the 20th century, Greater Los Angeles was one of the fastest-growing regions in the United States, but growth has slowed since 2000. At the 2010 U.S. census, the smaller Los Angeles metro area had a population of nearly 13 million residents. In 2015, the Greater Los Angeles population was estimated to be about 18.7 million, making it the second largest metropolitan region in the country, behind New York, as well as one of the largest megacities in the world. Over time, droughts and wildfires have increased in frequency and become less seasonal and more year-round, further straining the region's water security.

Exide is one of the world's largest producers, distributors and recyclers of lead-acid batteries. Lead-acid batteries are used in automobiles, golf carts, fork-lifts, electric cars and motorcycles. They are recycled by grinding them open, neutralizing the sulfuric acid, and separating the polymers from the lead and copper. In the US, 97 percent of the lead from car batteries is recycled - which is the highest recycling rate for any commodity. Most states require stores to take back old batteries.Since 2010, operations at seven Exide lead-acid battery plants have been linked to ambient heavy metal levels that posed a health risk to the environment and thousands of residents in neighborhoods surrounding the Exide plants. Exide has been found to be a significant source of lead emissions and/or contamination in Crescentville, Philadelphia (1920 - 1978); Los Angeles County; Frisco, Texas; Muncie, Indiana; Salina, Kansas; Bristol, Tennessee; Reading, Pennsylvania; and Forest City, Missouri.

No. 3751 served in passenger duties until being retired in 1953. The locomotive was then placed on display in San Bernardino until it was restored to operating condition in 1991. It is currently located in the Central City East neighborhood of Los Angeles and has been listed on the National Register of Historic Places since 2000.

The locomotive is currently owned and operated by the San Bernardino Railroad Historical Society, which uses the locomotive to haul occasional mainline excursion trains. However, a federally-mandated 15-year inspection put it out of service for three to four years. 3751's current overhaul is estimated to be completed in 2022.
