Mexicana de Aviación Mexicana de Aviación Compañía Mexicana de Aviación, S.A. de C.V. (commonly known as Mexicana) was Mexico's oldest airline and one of the oldest continuously single-branded airlines (after KLM, Avianca and QANTAS), and Mexico's biggest and flagship airline before ceasing operations on August 28, 2010. The group's closure was announced by the company's recently installed management team a short time after the group filed for Concurso Mercantil (Mexican law equivalent to US Chapter 11) and US Chapter 15. On April 4, 2014, a judge declared Mexicana bankrupt and ordered to start selling off the company's assets to repay the airline's obligations.
ALCO S-2 and S-4 often as their EMD SW9 number 2112, the unit is operational. Louisville & Nashville rebuilt many of their Alco switchers with 12-567 EMD prime movers in an effort to standardize their switching fleet. One of these, S4 (or S4m as rebuilt) #2326 survives at Gerdau Ameristeel in Cartersville, GA. Ameristeel recently donated the locomotive to the Southeastern Railway Museum at Duluth, GA. The Oil Creek and Titusville Railroad operates S-2s #75 and #85 on its tourist/freight railroad. The Virginia & Truckee Railroad acquired an S-4 from PPL Montana in 2010. The locomotive is in operable condition & slowly being repainted
