The railroad operates over  of track between Point Comfort, Texas (at the Port of Port Lavaca - Point Comfort) and Lolita, Texas, where the railroad transfers cars with the Union Pacific Railroad. PCN was purchased by the holding company RailAmerica in 2005; RailAmerica in turn was purchased by Genesee & Wyoming. The railroad's traffic largely comes from aluminum products from Alcoa World Alumina and Chemicals as well as plastics. PCN hauled around 12,500 carloads in 2008. Gallien-Krueger  Gallien-Krueger, also referred to as 'GK' (as in their logo), is a bass amplifier and speaker cabinet manufacturer. The company is based in Stockton, California, and was founded in 1968. Robert Gallien started his company, then named GMT, from his garage in 1968 in San Jose, California, while working as an engineer for Hewlett-Packard. His first amps were the GMT 226A and 226B (named after their power output) and were unconventional in their design because they were built around transistors instead of tubes. Carlos Santana was one of the first to buy a GMT 226A (serial #6) and it can be clearly seen in the Woodstock movie. In the early 1970s Bob Gallien teamed up with fellow HP engineer Rich Krueger and the company was renamed from GMT (Gallien-Martin-Taylor) to Gallien-Krueger. Although Rich Krueger is no longer involved in the company it has retained his name. In 1983 Gallien-Krueger launched the bass amplifier that would define the future of the company, the 800RB. The GK sound is defined by a dry "growl" and a quick reaction from the class H power amplifier. GK engineered the MB200, which was the smallest and lightest 200W bass amp available when it launched, and the 250BL, the first channel-switching bass amp. The company stopped producing electric guitar amplifiers in the early 1990s but continues to make bass amplifiers and bass cabinets. In November, 2013, the company paid a fine to the FCC for producing non-compliant digital radio products. Artists using GK equipment include Flea of the Red Hot Chili Peppers, Velvet Revolver's Duff McKagan, Tom Hamilton of Aerosmith, Ted Dwane from the Mumford and Sons, and others.
