Dear Sirs:
The Massachusetts Bay Transportation Authority is a regional public transportation agency providing a wide variety of services in the Boston Metropolitan Region including rapid transit, streetcar, commuter railroad, trolley coach, and motor bus operations. The Authority contracts with the Boston and Maine Corporation, a Class 1 main line railroad, for the operation of commuter rail services in the area north and west of Boston. A total of 249 schedules are operated each weekday on four main routes from 12.03 to 35.33 miles in length.
Beginning in 1952 the existing rolling stock used for these services was replaced with self-propelled rail diesel cars permitting faster, more frequent services with extreme flexibility in train makeup. At the present time, 84 of these cars provide all services on the Boston and Maine lines.
Since August 30, 1976, a Fiat model 7222 rail diesel car, constructed for the Italian State Railways and modified for operation in the United States, has been operated in offpeak service on these passenger lines. As we have only one car and it cannot multiple with our existing cars, we have not operated it on peak period schedules. However, large numbers of passengers have been carried regularly. The normally assigned engineman on each of the schedules on which the car operates has been trained to operate this vehicle so that considerable experience has been gained with the handling of the car by many different men.
During the months of December, 1976 and January, 1977 the Boston area experienced an unprecedented period of continuous cold temperatures accompanied by three major snowstorms causing many passenger services to be delayed or annulled due to roadway or equipment problems.
The Fiat car has operated most successfully during this adverse period and during the preceding temperate months. On its third day in service, this car struck a large boulder placed on the Gloucester Branch by vandals resulting in disablement of the vehicle. However, repairs were quickly made and the car was back in service two days later.
Since that time, the vehicle has covered all assigned schedules without delay chargeable to equipment problems, and on several occasions has pushed in disabled older cars.
In addition, we have conducted a survey among a number of those passengers who have ridden the car, asking a number of questions concerning the environment of the vehicle, and have received consistently favorable responses indicating an enthusiastic public reception.
Very truly yours,
B. H. Clarke, Jr.
Chief of

The light Diesel railcar built for the Italian State Railways is of the bogie type with hydro-mechanical transmission (fluid coupling plus 5-speed mechanical gearbox).
Each railcar is powered by two FIAT 821732, 280 HP (UIC nominal) rated on-board from 200 to 250 HP horizontal supercharged engines, large-scale produced for road vehicle traction (trucks and buses).
Railcars are suitable for interconnection with other railcar of the same type so that from any one cab a single driver may control four traction engines.
The 1-A arrangement bogies are designed to provide passengers with notably high riding comfort even at elevated train speeds.
They in fact belong to the same class of bogies fitted to the national and international TEEs designed and built by FIAT.
Interior arrangement is as follows:
Driver's cab; Baggage room;
Passenger compartment - 1st Class (12 seats);
Passenger compartment - 2nd Class (32 seats);
Passenger compartment - 2nd Class (24 seats);
Driver's cab.
Acess to cars is gained through four pneumatically controlled entry doors (two to each side).
Passenger compartment heating is provided by radiating convectors through which flows water recirculated from
Diesel and from an automatically-controlled fuel-fired boiler.
The unitized construction bodywork is rated to 150 Tons compressive strength.
Heat insulation is ensured by glass wool panellings.
Electrical system services supply is 24 Volts D.C. by lead storage batteries.
Continuos, automatic compressed air braking system.
