A train of the Boston & and Maine's Budd Rail Diesel Cars slows to a stop at Wakefield, Massachusetts in May 1965 to take on Boston-bound commuters. The B&M was the largest operator of these self-propelled diesel-hydraulic cars, owning 109 units divided between four different models. The number of the lead unit is unknown, but it is likely of the RDC-1 type with seating for 90 passengers. Those following in mid-train are either of that type or the RDC-9 type, which lacked cab controls.
