One of the public "trams" which make continuous circuits of the individual "Satellite" terminals of the various airlines for the convenience of connecting passengers at very nominal cost. 

A rather unusual-looking electric car, No. 9310 is a rail grinder, which used to grind down rough spots on streetcar rails in Los Angeles. The barrels held water used in the grinding process. Built in 1925 by the Los Angeles Railway in their own shops, 9310 is shown here at the Orange Empire Trolley Museum, where it is on display with many other streetcars and other railway vehicles.
