The number of passengers carried by the Interboro Lines during the fiscal year 1921 was 1,013,678,831. This figure represents 2,773,479 passengers per mile of track. In the main 4-track subway 10-car express trains are operated during rush hour periods on minimum headways of 108 seconds.

_Power Supply_

The power generating equipment of the Interborough includes briefly the following:

════════════════════════════════╤═══════════ 59th St. Power Station │ Total Kw. ────────────────────────────────┼─────────── Turbo-Generators 3-30,000 kw.│ 90,000 Compound Units 5-15,000 kw.│ 75,000 Engine-driven Units 4- 7,500 kw.│ 30,000 ├─────────── Total │195,000 Kw. ────────────────────────────────┴───────────

════════════════════════════════╤═══════════ 74th St. Power Station │ Total Kw. ────────────────────────────────┼─────────── Turbo-Generator 1-60,000 kw.│ 60,000 Turbo-Generators 3-30,000 kw.│ 90,000 Turbo-Generator 1- 7,500 kw.│ 7,500 Engine-driven 3- 7,500 kw.│ 22,500 ├─────────── Total │180,000 Kw. ────────────────────────────────┴───────────

Power is generated 11,000 volts three-phase 25 cycles and transmitted principally underground at 11,000 and 19,000 volts. The total energy generated in the two main sections at 59th St. and 74th St. for the year 1921 was 830,000,000 kw-hrs.

_Substations_

For supplying 625-volt direct current to the rapid transit lines, there are a total of 25 substations containing 129 synchronous converters aggregating 283,000 kw.

_Distribution_

Propulsion current is delivered to trains through an unprotected over-running third rail weighing, in the old subway 75 lbs. per yard, on the elevated 100 lbs., and in the new subway 150 lbs. per yard.

_Rolling Stock_

The motor car equipment on the Manhattan Elevated lines includes over 800 cars which have been in operation since 1902-4 with GE-66 motors and Type M control. These cars after 20 years of hard service are referred to as the “back-bone of the system.” Frequent additions have been made to elevated and subway equipment so that the total rolling stock at the end of the fiscal year 1921 was as follows:

INTERBOROUGH RAPID TRANSIT ROLLING STOCK EQUIPMENT

MANHATTAN DIVISION Passenger Motor Cars 1016 Passenger Trailers 721 Service Motor Cars 4 Service Trailers 56 ELEVATED EXTENSIONS Passenger Motor Cars 476 SUBWAY DIVISION CONTRACTS 1 & 2 Passenger Motor Cars 785 Passenger Trailers 352 Service Motor Cars 10 Service Trailers 46 SUBWAY DIVISION CONTRACT 3 Passenger Motor Cars 581 Passenger Trailers 217 Service Motor Cars 1 Total Motor Cars 2873 Total Trailers 1392 Grand Total 4265

The longest ride on the system for a single fare is from the terminus of the White Plains Road line at 241st St. near the Northern boundary of the city, the entire length of Manhattan and the Bronx and through the Eastern Parkway Subway to Linwood Avenue, a distance of about 26 miles. The maximum grades encountered are 4½ per cent.

PHILADELPHIA RAPID TRANSIT CO.

The present rapid transit facilities of the City of Philadelphia include Market St. Subway-Elevated line extending East from the 69th St. Terminal to the Delaware River. The tracks are elevated from 66th St. to 22nd St. and pass in subway under the business section to another elevated section on Delaware Ave. This line first began service in 1905 and during the year 1920 handled approximately 80,000,000 passengers.

As far back as 1912 an exhaustive study of the city’s transportation facilities was made and a comprehensive program of extensions was proposed for the rapid transit system. Owing to legislative delays, and conditions due to the war, progress has been delayed on this program so that so far only the Frankford Elevated line has been built. This is now nearly ready for operation, from the foot of Market Street to Frankford, a distance of 6.4 miles all double tracked. Other extensions planned for construction in the near future include a four-track subway running north and south under Broad Street, and an elevated line extending from the present Market Street line at West Philadelphia to Darby.

The present elevated-subway system is double tracked throughout and multiple unit trains up to seven cars each are operated on headways down to two minutes. No express service is operated, all trains making every stop.

_Power Supply_

The Philadelphia Rapid Transit Company’s principal power station is at Delaware Avenue. Steam turbine generating equipment totalling 58,000 kw. is in service in three stations and is designed for 13,200 volts 3-phase 25 cycles at which it is transmitted to the substations. One or two direct-current stations are still available for supplying 600 volts direct to the trolley. Power is also purchased from the Philadelphia Electric Co. and the Philadelphia Hydro-Electric Co.

_Substations_

The company operates a total of 17 substations used for supplying both surface and rapid transit lines. These stations contain a total of 65 units aggregating 103,500 kw.

Power is distributed to all lines at 600 volts and on the rapid transit lines is collected from an under running third rail similar to that used on the New York Central Electric Zone.

_Rolling Stock_

The rolling stock used on the Elevated-Subway line includes 215 motor cars each equipped with two motors. Trains are made up of all motor cars, no trailers being used. General Electric motors are used throughout including GE-66 and GE-222. The Frankford extension will be operated with 100 motor cars each equipped with two GE-259 motors.

Bulletin Number 49 is a reproduction of a 1922 General Electric Company pamphlet. Since that year many changes have been made in the systems described and new lines have been constructed in Cleveland, Toronto and Montreal. Another is under construction in the San Francisco area. Additional copies are available at $1.50 each from the Electric Railway Historical Society, Box 3305, Chicago, Ill. 60654.
