Caption: LRC-2 No. 6904, constructed by BBD in 1980, is shown at the head end of rather bizarre consist; F9B No. 6634/EGU/Tempo coaches. Reason for the Electrical Generating Unit is the lack of pass through HEP cables on the F9B. To enhance motive power flexibility CN modified three former NSC built smooth side baggage cars with diesel generator HEP equipment such that any suitably geared locomotive could be deployed into Tempo service.
