Southern Pacific freight train symbol PBRVY near Luling, TX

The SP was still experimenting with radio controlled helper sets in late 1977. Extra 9329 West (train symbol PBRVY) is returning power to West Colton on December 14, 1977. Although this train has eight engines, I think only the first, second, third, and sixth units are online. The green BN B unit holds the radio control equipment. Disk 101
