WPacific Electric's final order for interurban cars was placed with The Standard Steel Car Company of Hammond, Indiana, in 1924; it called for a total of fifty all-steel cars of the same general design as its 1200 Class but somewhat lighter and slower. Numbered 100-1149, the new cars cost $1,850,000 and were a dramatic reaffirmation of PE's faith in the interurban.

WIn design, the 1100s were a modified 1200; they used double doors to permit quicker loading-unloading, particularly aimed at Northern District service conditions which 1100s were earmarked to serve. PE officials at the time desired a super-600 Class car; they felt a larger, faster center-entrance car would be ideal for the North. They were overruled by Southern Pacific officials who preferred a car based on SP's O-A-B cars (See 400 Class).

W1100s were equipped with PE's usual Westinghouse automatic coupler; they could couple with 1200s, but could not MU together.

WThe Elevens were shipped from Hammond on their own wheels; the first fifteen arrived at Torrance in June, 1924, and were equipped with motors, controls, trolleys and other electrical apparatus immediately. They entered service on the Pasadena lines in August, amid much favorable publicity. The entire class was in service by the end of October, 1924.

WAll fifty cars were upgraded in 1942-43 but remained essentially suburban cars in performance; with but 34" wheels and modest motors, the Elevens were slow; 47 mph was tops for them.

W1942 REHABILITATION PROGRAM

WIn 1942-43 the 1100s were put through Torrance Shops for long overdue rehabilitation. All received a mechanical overhaul and painting, inside and out; electric markers were also added. Many received better seats and interior lighting.

WAbout 23 Elevens received Heywood-Wakefield Type 327-M divided seats, which were removed from 19 scrapped 950s and 10 modernized 750s. Records are not clear as to which Elevens goth these seats, but among them were: 1100, 1101, 1103, 1106, 1107, 1108, 1109, 1112, 11113, 1115, 1116, 1119, 1120, 1121, 1122, 1123, 1124, and 1125.

WIn July, 1949, five Elevens were equipped with farebox holders for service on the Watts local line: these were 1105, 1122, 1123, 1127 and 1147.

WThe last days of the Elevens on PE were notable for the following:

W1119 suffered fire damage at Shamrock Avenue, Monrovia, in June 1950; when conductor placed trolley on wire, getting car ready for service, the worn overhead fell on the car. Car was repaired by PE in 1952 for sale to Buenos Aires.

W1120 was out of service and stored at Torrance on account of collision damage when it hit a Union Pacific bus at Huntington Drive & Garfield Ave. on May 11, 1950; repaired 1952.

W1110 and 1130 were involved in a sideswipe collision at Colorado & Fair Oaks, Pasadena, in July, 1950; both repaired at Torrance.

W1144 was noted stored at Torrance in August 1950, with drawhead torn off; repaired for Argentina sale, 1952.

WPrematurely withdrawn from Santa Anita service in 1950 on account of bad wheels and sent to West Hollywood for storage in February, 1951, were: 1102, 1114, 1118, 1125, 1136, and 1148.
