L CAL0031 Pasadena Sub Local passes the classic ATSF cantilever signal at Glendora behind two warbonnet GP60Ms. The lead unit (still in ATSF paint), 146, was specially painted in a Maersk livery in 1990 for a publicity shoot. The Pasadena Sub is owned and controlled by Metrolink, but generally only sees this weekday local. It is controlled by track warrant, but still maintains its ABS signalling, making for great scenes such as this.
